Micro workstations get graphics boost with RTX

Revit 2021.1 extends focus on automation utodesk has concentrated on automation and computation for the new Revit 2021.1 release, adding new sample studies for Generative Design for Revit, and introducing a new 2.6 version of Dynamo for Revit along with new Dynamo nodes. The software also offers better interoperability with Autodesk Infraworks and Autodesk FormIt Pro and enhanced data exchange with third party tools including McNeel Rhino and Trimble Sketchup 2020.

P and Dell have beefed up the graphics in their micro workstations, adding custom versions of the Nvidia Quadro RTX 3000 GPU to the HP Z2 Mini G5 and the new Dell Precision 3240 Compact. Ultra-small form factor (USFF) workstations typically feature entry-level CAD-focused GPUs like the Quadro P1000, so this is big news for those who want more graphics performance without having to sacrifice valuable desk space, especially when working from home. The Dell Precision 3240 Compact measures 18.8 x 7.0 x 17.9cm and starts at 1.71kg, while the HP Z2 Mini G5 has a slightly bigger footprint but is 1.2cm thinner. Both machines can be VESA mounted behind a display or under a desk. The Quadro RTX 3000 GPU features

dedicated RT cores for ray tracing and Tensor cores for AI denoising, making it suitable for entry-level GPU rendering, as well as real-time viz and VR. It is not a standard desktop graphics card, rather a custom version of an MXM form factor GPU typically found in mobile workstations. In the HP Z2 Mini G5 and the Dell Precision 3240 Compact we expect it will offer slightly better performance than Quadro RTX 3000 GPUs found in slimline mobile workstations. The HP ZBook Studio G7, for example, uses a ‘Max Q Design’ variant, so is clocked a touch lower. Both workstations feature 10th Generation Intel Core CPUs with up to 10 cores and up to 64GB of memory. ■ zworkstations.com ■ dell.com/precision

P has taken a fresh look at its large format printer range, launching new machines targeted at SoHo (Small office / Home office) AEC businesses. These include the HP DesignJet Studio, which features a sleek white facia and wood or steel finish, and the DesignJet T200 and T600 Series, which HP claims to be the world’s smallest plotters. All three DesignJets work with the HP Smart App for iOS and Android that allows users to print and manage jobs from ‘virtually anywhere, anytime’. Meanwhile, users can send multiple files in one click (PDF, JPEG, TIFF, DWF, and HP-GL/2) from PC or Mac, and with HP Click software, documents of different sizes can be printed automatically (A1/D

and A3/B or A0/E and A3/B). With its natural materials and sleek aesthetic, the HP DesignJet Studio printer is not meant to be tucked away in the corner of an office. The printer comes in two sizes - 24” (A1/D) and 36” (A0/E) – and with an automatic A3/B tray, multi-size projects can be printed automatically without manually switching the media source. The HP DesignJet T200 Printer Series is primarily a desktop 24” (A1/D) printer, built to fit in the smallest of spaces, although there’s an optional stand and optional automatic sheet feeder. The HP DesignJet T600 Printer Series is available in two sizes - 24” (A1/D) and 36” (A0/E) - and comes with a built in stand and output bin and automatic sheet feeder. ■

Performance boost for Vectorworks 2021 ith the new 2021 release of Vectorworks, users with multi-core workstations are said to experience up to five times faster file loading and improved transition time when changing 3D views. According to the developers, the Vectorworks Graphics Module (VGM) also means no delays when navigating in 3D with the flyover tool. Other new features of

Vectorworks 2021 include the Project Sharing server that offers a ‘versatile multi-user environment’; better interoperability capabilities with Excel Import/Export and PDF Drawing Marker Links. Smart Options Display allows users to stay in the modelling space without needing to constantly move their mouse between drawing area and tool palettes. Elsewhere, the quick search command helps

users find and activate any tool or menu command by typing what they need, while Smart Markers make it easier to use drawing markers when generating documentation. To support a ‘better BIM workflow’ for architecture and landscape professionals, Vectorworks 2021 features new materials that define both the graphical attributes and data of building materials all in one location. ■ vectorworks.net/2021

winmotion 2020.2, the latest release of the AEC focused real-time viz tool, includes new tools for animation and phasing, more realistic materials and effects, and new animated and smart assets. For animation, the software features a wide range of new door assets that automatically snap and scale to fit within existing openings and can be set to

automatically open based on the proximity of camera and/or people assets. Custom objects such as doors, windows, and elevators can also be animated. A new multi-track timeline-based phasing tool is designed to make it much faster and easier to create phased video of a project’s construction schedule, or to present different variations sequentially. ■ unrealengine.com/twinmotion

Revit models import directly into Arkio rkio, the VR-centric collaborative spatial design tool, has improved its interoperability with Revit, offering a bi-directional workflow. With the Arkio Revit plug-in users can export a Revit model to Arkio. Once the Revit model is inside Arkio, users can add markups, sketch new design ideas or add

geometry to create different design options. To export the design back to Revit, Arkio shapes convert to Revit mass families or generic shapes. Built-in Arkio assets, sketches, imported buildings and models convert to customisable families. Program data even exports as object parameters that can be used in schedules. ■ arkio.io

Laser scan meshes streamed into Unreal intoo is developing a new cloud-client solution that will allow mesh-based laser scans to be streamed from the cloud directly into Unreal Engine. The idea is to create ‘rich, immersive experiences’ that mix as-built scan data with as-designed CAD and BIM models to address QA/QC workflows for construction. The technology uses Cintoo’s Cloud platform that turns terrestrial laser scans

www.AECmag.com

p06_08_09_10_AEC_JULAUG20_News.indd 9

into high resolution meshes that are 10 to 20 times smaller than the source scans and include multiple levels of detail. The datasets are ‘fully cloud compatible’ and can be streamed to a WebGL browser on desktops, laptops, tablets and VR headsets. The development is being funded in part by Epic Games, who has awarded Cintoo an ‘Epic MegaGrant’ as part of a $100m program designed to help firms accelerate work done with Unreal Engine.

Graphics boost for VRcollab Rcollab LITE v0.10.26, the latest version of the AEC-focused collaborative VR tool, features improved graphics, easier sharing of meeting links and a new organisation dashboard. The graphics enhancements include Screen Space Reflections (SSR), which adds reflections, giving objects a glossier look; HDR Bloom, which adds a “glow” to reproduce an imaging artifact of real-world cameras; and an advanced windows (glass) setting that adds realism to glass windows and how light passes through. The new release also makes it easier to invite others to join a VRcollab coordination, design review or presentation session. Previously, guests had to manually insert the code generated by the meeting host, but now meeting links automatically open the software.

Reality capture app uses LiDAR sensor on iPad Pro obile mapping startup Sitescape has developed a reality capture app for the 2020 iPad Pro that uses the device’s built in LiDAR sensor to create dimensionally accurate point cloud datasets. According to company CEO Andy Putch, the AEC industry is a key market for the software where it can be used for progress monitoring, documentation, and remote site access/ collaboration. Putch told AEC Magazine that the Sitescape solution is not an alternative to SLAM or traditional laser scanners. “It comes at a vastly lower price point, is suitable for novice users, and produces

results in the field that can be immediately shared,” he says. Accuracy is said to be around +/- 1” for linear measurements, while the max range of the LiDAR sensor is 15 feet. “We’ve found that indoors, tracking drift is very low (1” - 2”) for distances below 40’ and increases for larger distances,” says Putch. “A single scan can cover 1,500 sq ft with suitable detail and multiple scans can be captured back to back and then registered into one continuous model.” The software can export PLY point clouds, but there are plans to add more formats in the future. ■ sitescape.ai

NBS Chorus for Small Works launches BS Chorus for Small Works is a new version of the specification platform NBS Chorus, created specifically for architects, engineers and designers who write specifications for smaller works and projects. The software is cloud-based so multiple users across different locations can develop specifications together.

and not overly technically complex, such as teaching blocks, retail/industrial units and so on. The software comes with a speciallyselected set of NBS content. NBS Chorus for Small Works can plug-in to a range of design tools, including Revit, ArchiCAD and Vectorworks and ‘seamlessly’ allows the architectural model to be updated as the specification changes. ‘Specification notes’ record all project decisions directly in the specification. ■ thenbs.com/nbs-chorus/small-works

News analysis

HP launches 1U rack workstation to round off ZCentral remote workstation offering P has filled a big gap in its Z workstation portfolio with the introduction of the HP Z Central 4R, a dedicated 1U rack workstation that allows users of CAD, simulation, rendering and other software to connect remotely over a 1:1 connection. The timing of the launch is extremely relevant, as more and more firms revaluate their work from home strategies due to Covid-19. But this isn’t a knee jerk reaction from HP. The HP Z Central 4R has been in development for some time and is part of a wider remote workstation strategy based around HP ZCentral, a software suite that includes dedicated remoting software and a software broker. Indeed, we first heard that HP was developing a 1U rack workstation back in 2019, but understood there had been some issues with Hewlett Packard Enterprise (HPE) due to concerns about crossover with HPE’s GPU servers. To our mind the HP Z Central 4R is 100% workstation, and the fact that it’s housed in a datacentre is somewhat irrelevant. The machine does not support virtualisation and each user gets access to a dedicated machine – CPU, GPU, memory and storage – over a 1:1 connection. In fact, the HP Z Central 4R is essentially the desktop HP Z4 in a different form factor. The HP Z Central 4R packs a lot of power for a 1U workstation, with Intel Xeon W processors up to 18 cores, a single high-end GPU up to the Quadro RTX 8000, and up to 256GB memory. Compared to the 1U Dell Precision 3930 Rack and the Fujitsu Celsius C780, it has a similar choice of GPUs, but more modern CPUs with more cores. When HP launched its HP ZCentral software in November 2019, it placed a big emphasis on the HP Z2 Mini, a tiny desktop workstation that can be rack mounted, along with HP’s other desktop workstations, the Z2, Z4, Z6 and Z8. HP confirmed that it will continue to promote the HP Z2 Mini as part of its ZCentral offering, highlighting the fact that users can achieve better density (56 units can be squeezed into a standard 42U rack). However, we don’t imagine many firms would now actively invest in the Z2 Mini as a remote solution as it lacks the manageability and serviceability of the HP Z Central 4R which is built specfically for racks.

www.AECmag.com

p13_AEC_SEPTOCT20_HP_News.indd 13

Instead, firms are more likely to redeploy existing Z2, Z4, Z6 and other desktop machines to protect their investment, rather than buy new ones. In saying that, in smaller volumes, using desktop workstations as a remote resource still makes sense, as they make a lot less noise and don’t necessarily need an air conditioned cabinet or server room. In terms of hardware, the HP Z Central 4R has a toolless design for easy access and maintenance. There’s a front security bezel, which prevents access to the front ports, drive bays and PSUs, and a ‘locator LED’, which can be turned on from the ZCentral admin console to help locate specific machines in the event of a failure. The machine can support up to two 675 watt power supplies, which can be set up in aggregate or redundant mode, and up to four 2.5-inch drive bays (or two 2.5-inch and one 3.5-inch), and two M.2 NVMe SSDs. Of course, hardware is only one part of HP’s ZCentral remote workstation solution, which also includes remoting software ZCentral Remote Boost (formerly known as HP RGS) and a software broker, HP ZCentral Connect. Like most remoting software, ZCentral Remote Boost works by sending an encrypted and encoded stream from the remote workstation to the client device, while keyboard and mouse signals are sent back. The ZCentral Remote Boost sender software comes free with all HP Z workstations and anyone can download receivers for Windows, Linux, and MacOS. ZCentral Remote Boost supports 4K and multi-display setups and also works with the 3Dconnexion SpaceMouse. HP is

currently in the process of improving support for Wacom tablets to give a more ‘natural inking experience’. ZCentral Connect provides a management and brokering capability for larger groups of remote workstations. Rather than typing in IP addresses users can simply click on a system name to connect. Through a console, the IT manager has full control over the pool of machines and can remotely power them on and off, as well as monitor all connections. System error alerts will pop up if a machine can’t boot or a PSU has failed. With the launch of the HP Z Central 4R, HP has finally added the missing piece to its remote workstation solution. While the HP Z2 Mini supported the needs of CAD users, and delivered great density, using desktop workstations in racks isn’t the most elegant solution. In addition, workflows that demanded more GPU and CPU resources could only be supported by the significantly larger desktop HP Z4 (4U). Now with the new HP Z Central 4R workstation, complete with Xeon W CPUs and Quadro RTX GPUs, HP can pretty much cover all bases, from CAD, all the way up to simulation, design viz and other compute / graphics intensive workflows. More importantly it can deliver everything in a compact and manageable 1U unit, designed specifically for racks, which, along with the integrated ZCentral software, should present a much more attractive solution for engineering and architecture firms looking to build a remote workstation capability. ■ zworkstations.com

The future of R Autodesk’s recent admission that there’s been a multi-year lack of development of Revit because of the concentration on cloud and construction has left many frustrated architectural practices wondering what the future of this 20 year-old BIM tool will be. Martyn Day examines the tea leaves

utodesk acquired Revit Technology Corporation (RTC) with its Revit application in 2002 for $133 million cash. While RTC made a lot of noise, and its core parametric technology was innovative, it did not generate much revenue and, in fact, had few customers. Up to that point Autodesk had been trying to morph AutoCAD into a full-on architectural modelling tool with the unfeasibly complicated ‘Architectural Desktop’ variant. One of the underlying key driving factors to the acquisition was that five years previously Autodesk dropped out of buying mechanical CAD (MCAD) tool Solidworks (Dassault Systèmes paid $310 million) which then went on to dominate desktop MCAD as users moved from UNIX to Windows. Autodesk’s CEO at the time, Carl Bass, didn’t want to make the same mistake again. Had Autodesk bought Solidworks, it 16

p16_17_19_22_23_AEC_SEPT20_Revit.indd 16

would not have spent millions on developing Inventor and then Fusion and would have been the number one player in desktop MCAD. The Revit acquisition protected Autodesk dominance in AEC and eventually proved to be a savvy investment. The excitement of innovative code and doing things much better than previous generations of software is typically reserved for the early phases of development. Updates can be frequent and big; the potential can be seen. However, this furious initial phase typically slows down as a product ages and competition subsides. There is a lifecycle of software and to understand this better it helps if you can think a bit more like a software developer. To generalise, the CAD software industry, on the micro scale, appears to have evolved to deliver the yearly evolution of authoring tools, executed on rolling 3 - 5 year development plans, along with equally evolving business models. For

instance, we had perpetual licensing, where customers bought the perpetual right to access a version of software. Now the trend is for subscription licensing, where customers lease the right to use the software over a set time. The future looks to be heading towards a pay-peruse or subscription hybrid. However, eventually software applications age; years of new layers of features compound to make products cluttered. The internal ‘wiring’ gets messy and fundamental changes can cause ‘regressions’ bugs in features that used to work but now don’t. At this point software companies need to make important decisions on how to maintain their success. In the software world, a ten-year-old software program is deemed old. If a software package is extremely successful, the common-sense thing to do is to stretch it out and to do enough to retain the loyal base and keep the competition at bay. If www.AECmag.com

There is no Revit 2.0 and the future appears to be some kind of slow absorption into a cloud-based construction system with new thick client applications eventually replacing the single monolithic Revit application

you do a good enough job, there are few, if any, competitors and software is ‘sticky’. But even here, at some point, software developers usually take the risk of writing something new from scratch, or they acquire a start-up that has done that work for them as it’s better for them to kill their most successful products, rather than have a competitor do it. In this case, Autodesk decided to buy the next generation to kill Architectural Desktop, and switched BIM horses.

Development velocity If you want to understand where your chosen CAD product is in its lifespan, look at the development velocity. The less that is added each year, the more likely it is very mature. If new features appear to be ‘onion skins’ to the application, as opposed to fundamental core rewrites or big new dollops of functionality, it’s most likely that the team don’t want to dig into www.AECmag.com

’’

the product’s guts for fear of playing Buckaroo with all the dependant code. Another option is to redevelop applications on the fly, rewriting core features sequentially and doing a lot of under the bonnet work while keeping the same interface and file format – a case in point is ArchiCAD which had good multi-core support added at a platform level and AI added to rewritten features like the stair tool. While this may keep the code refreshed, fundamental principles remain the same and this can come unstuck if industry workflows change or a new upstart comes out without decades of baggage. Moving to the macro level, every ten or twenty years the fundamental underlying technologies are renewed, and that could be hardware (like processors), operating system (DOS to Windows NT) or the change we see today, to cloud. At each of these technology boundaries,

firms and market leading products can lose market share, even go extinct, if the software firms fail to manage the transition by having planned for change and being the best to leverage the new technology platform. This is why we are seeing so much concentration on, and development around, cloud-based apps, despite the majority of users being fairly happy on their desktop PCs. Historic examples that spring to mind are PTC, which was the leading desktop MCAD player with UNIX-based Pro/ Engineer. It was severely mauled by the new Windows upstart Solidworks because PTC failed to get to Windows quickly enough and kept its prices high. Autodesk had a serious wobble when it went from AutoCAD R12 to AutoCAD R13, from DOS to Windows NT, completely rewriting the code in C++, adding in solids and then trying to build vertical applications on constantly-moving, buggy base code.

Autodesk was lucky that nobody was there to really pick up on the company’s self-inflicted errors, but the effects lingered long into AutoCAD R14 and partially led to the decision to develop Inventor, which was Autodesk’s first new in-house developed code-base since AutoCAD to tackle the MCAD market and specifically Solidworks. These generational changes are major hurdles for software firms to negotiate and not everyone gets out alive.

complain at price hikes. Architects in Australia/NZ, Hong Kong and South Africa had all attempted to engage on the same subjects. It seems that in private Autodesk had more than enough warnings that its best and most mature Revit customers were all feeling very frustrated and sought a collective response. The Open Letter movement (letters-toautodesk.com) now stands at 166 global firms directly signed up at the board level and as we were going to press, Brazil’s National Association of Architecture and Consulting Engineers (sinaenco), representing a whopping 30,000 firms, also released a similar open letter after its members took part in a questionnaire which backed the sentiments of the original UK/Aus letters group. It cannot be said that these grievances are just the feelings of a few practices in the UK. This is a pandemic in the mature Revit base. These formal and informal groups are now talking and sharing experiences and opinions. We are essentially seeing the ‘unionisation’ of BIM-

Its other defence, that it needed to allocate resources to BIM 360 and Construction Cloud, was perhaps less persuasive to architects.

The first executive call was described as a listening meeting, where the Group preThe open letters sented their grievances on a wide range of Coming back to where the current AEC topics (pricing, licence changes, interopermarket is within these various developability, Suites/Collections ‘product stuffment cycles, and we find ourselves at one ing’, development, non-compliance audits) of these key inflection points, as the platand the second revolved around wishlists form transitions from desktop to cloud. and features.

BricsCAD BIM

BIM that respects Design If you want to construct something, you need to design it ﬁrst. You know this, and we know this – but it seems that other software vendors have completely forgotten about design and architecture. Bricsys has not forgotten – in fact, we live for this. BricsCAD® BIM is the modern, ﬂexible Building Information Modeling system that starts with BIM-ready modelling from the concept stage.

Start in solids with full freedom Begin your design by sculpting freely, using our intuitive direct modelling engine. It keeps your BIM light and responsive and allows you to express your design without concern for families and classiﬁcations.

When you are ready, your study model becomes the BIM with the help of our A.I.-based workflows. You can add detail continuously across the entire model with the help of these intelligent tools.

The future

development of Project Quantum (tinyurl. com/quantum-aec). The idea was a centralised cloud system, in which all AEC participants would work and be able to see the real time geometry changes of other users. This was a great concept and the dream was that all project participants could work on a single model, a data centric approach. The problem is it seemed to vanish, with the excuse being made that the technology was in some way re-appropriated to a different team. Talking with Anthony Frausto-Robledo, the owner of Architosh (architosh.com) he seems to have an Autodesk insight that Quantum was little more than a ‘PowerPoint deck’ at the time. Roll forward to 2018 and Autodesk has Project Plasma (tinyurl.com/plasma-aec), which built on some of Quantum’s core principles, expanding to embrace digital fabrication. Here the future was a central cloud database, with thick and thin clients accessing the data simultaneously and while catering to the needs of current design and build workflows, it would be designed to drive digital fabrication, off-

called Plasma anymore). The question will be what is the focus of the new system - architecture or construction? From conversations with Autodesk developers the primary focus will be on construction, not design, and this does have good reasoning. To design a workflow, you need to know the output and when defining a software application for AEC for the next 20 years, digital fabrication must be at the core. It’s not something that can be added in as a patch later on. A single design system that can take customers from conceptual (loose geometry) to 1:1 accurate models to generate Gcode, with everything in between, is a big ask. To some extent Autodesk already has the architecture market with Revit, but it wants to concentrate on cracking construction. As there isn’t anything out there to buy, Autodesk is developing itself.

In talking with the group, one of the most interesting aspects of discussion is ‘what is the future of Revit?’ It’s something that we here at AEC Magazine have been trying to prise out of Autodesk for many years now. After years of low level development and Autodesk’s focus being elsewhere, customers have a right to wonder what’s the plan? Will the current Revit be rewritten to make use of modern processors and GPUs? Will Revit be able to handle larger There is no Revit 2.0 models? Will there be a Revit 2.0? We have seen in the MCAD space Autodesk has been clear; the developAutodesk already make another new modment work it will be doing to Revit, based elling tool called Fusion, which will evenon the current roadmap (tinyurl.com/revittually supersede Inventor as its feature set road), does not involve a bottom up grows, utilising the rewrite.

how to decouple some of Revit’s sub services to work better with Autodesk’s Construction Cloud. He then went on to claim that Revit is being ‘modernised’ and ‘broken up into parts’.

Years away Reading this, Revit customers could be excused for wondering what on Earth is going on? Unless there has been a dramatic change of heart at Autodesk in the last week, there is no next version of Revit, no new generation, no fundamental rewrite. The Letters Group, while their input to the development has been welcomed, have had their expectations tempered to not to expect to see any radical rewrite of Revit. Autodesk’s historic lack of Revit development seems to have many reasons, a switch to construction, a switch to developing cloud services, while maximising the amount of money it can get (and value for shareholders) for doing as little development work on Revit’s old code. Thanks to the industry collectively calling Autodesk out, there will be some redress to the development and roadmap situation, a near-term win. This does not answer the long-term question of how can skilled architecture practices move beyond what’s possible today, when they feel limited by their 20-year old tool? The lack of development and focus gave the distinct impression that Revit was in, at best, maintenance mode and raised the question of its imminent demise. Conversations with users tended towards reciting the Monty Python ‘Dead Parrot Sketch’. The reality according to Autodesk, is that it was ‘only resting’. While ‘Plasma’ architecture might have a data back bone and new name now, it will be shown in some capacity at AU this year. However, this seems to be very early days and may well take a significant period of time to reach the market and then mainly for construction firms, not architects or design. The speed with which it can be brought to market will be a test for Autodesk’s Forge development system,

which should enable accelerated delivery of tools and workflows, but as I said, this is a massive undertaking. The Autodesk plan seems to be to try and keep Revit customers happier, in the meantime build the Construction Cloud, under the hood integrate Revit desktop subsystems to better work with its cloud services. Then over time, replace Revit with thick client applications for architecture, MEP and structural. My estimate is this could take a timeframe of six to eight years to complete. I do have serious concerns how the current Revit desktop, even with more development, can be stretched out to keep the attention of demanding architectural users.

Conclusion There is no Revit 2.0 and the future appears to be some kind of slow absorption into a cloud-based construction system with new thick client applications eventually replacing the single monolithic Revit application. Autodesk is technically ‘gapping’ between generations but is now desperate to try and reassure the Revit base that all is well. I’m not sure whether promising them that the same tool will be on Windows 2030 is an incentive to stay or go? Autodesk’s development focus is clearly on construction; the plan for architectural seems amorphous and not fully fleshed out. Without the intervention of the Letters Group, I doubt we would have seen the Revit product owners so visibly engaging with their users. With regards to licensing and costs, Autodesk has picked up that customers want pay per use (PPU). Looking at their current Token system, after 8 mins you get charged a whole day’s worth of tokens. 8 mins is the same as 23 hours, 59 mins 59 seconds. Most firms have Revit models that take upwards of 20 minutes to just load. So it costs a day’s worth of tokens to see your own model in Revit, let alone do any modelling. In PPU I’m hoping that Autodesk is

looking at better granularity on this, but I have concerns about cloud and PPU in general. Software companies will charge you to create your design, to store your design and then will make money from your supply chain accessing your design and using their tools on your data. Your data becomes a commodity in a pay to play system. This has all sorts of data protection and monetisation issues which need to be addressed. This moment is clearly a time for architectural firms to reassess BIM strategy, its usage, the workflows, the workarounds, partnerships, deployment, product mix. I am seeing clear trends where architects are reclaiming the design portion of the process and pushing BIM tools to the documentation phase, almost to the extent that it becomes a discrete process. BIM is too constraining for early stage design and seems to have not really delivered in automating the drawing process which was its main objective. From talking with the Letters Group it’s been really thought provoking discussing what comes next for design. This is something that the Letters Group will cover in detail in an unmissable panel discussion that will take place during AEC Magazine‘s NXT BLD Virtual conference next month (8-14 October 2020 – register free at nxtbld.com). In talking to Autodesk’s competitors over the last few weeks, many asked me, if Revit customers were so upset, why did they decided to write a letter and not just move to another system? It’s a good question. One of the firms involved in the open letter, described it as ‘having dug a hole so deep, that when you have serious concerns as to the direction you have travelled, and the costs now involved, you look up and see how far it is to get out, and the question is, whether you should climb out of the hole and start again, or keep on digging, in case it gets better.’ In many respects, the multitude of issues that the Open Letters group addresses take this beyond wanting a better Revit, it wants a better Autodesk.

sketching in mainstream design systems, is the dimensioning workflow for sketches. Rather than requiring formal dimensions, Shapr3D works on selections and pops up possible dimensions (click line, get a length dimension. Click two lines, get an distance or angular dimension etc.) - if you formalise then and dial in the values, then they persist during any subsequent edits to that sketch. You are able to construct well-built, robust sketches - it just take a little getting used to. While the sketch tools give you drawing capabilities, you’ll really want to be able to build those sketches into 3D forms. The majority of tools to do this are found in the Add and Tools toolbars. Add provides you with construction geometry, such as planes and axes, as well as the ability to import geometry from the iPad file system. It will also enable you to bring in an image as a reference - and considering the usefulness of Shapr3D for working up a concept, this makes huge sense. While those Add tools are useful, the real meat is found in the Tools toolbar. Here, you’ll get access to a number of standard and familiar feature operations. All of the classics are there: extrude, revolve, sweep, loft and shell. There are www.AECmag.com

p26_27_28_AEC_SEPTOCT20_Shapr.indd 27

also a number of Booleans (Union, Subtract, Intersect), as well as geometry projection, offsetting and a face replace. If you’ve used direct modelling operations before, then you’ll be familiar with how these systems work. It’s not so much about creating a linear history of geometric features, as much as creating, hacking, chopping and removing geometry to achieve the form you want. In the most recent release, the team has introduced an element of adaptivity to the user interface. Based on your current selection, the interface adapts to present you with a list of operations that can be applied using that selection. For example, if you select a single face, you can carry out a number of operations such as offsets or move, extrusions or cuts. If you then select an edge, then the selection of operations available filters down to operations that might use those two selections – such as a revolve or a loft etc. If you’ve not used direct modelling tools before, one point that’s worth considering is how the face selection and move tools (found in the Transform toolbar) work, as opposed to the features such as extrude. If you have an existing face that you

want to either cut into or out of your solid model, you can select the face and a small glyph appears giving you a direction. Drag that into the part and it cuts. Drag it away from the part and it will extrude that face. If you want a more complex extrusion with, say, draft added, then use the extrude command – you’ll see the draft angle glyph appears on screen.

Assembly organisation While Sharp3D doesn’t have the formal assembly modelling tools of a fullyfledged mechanical design system, it does have enough to allow you to create and manage a more complex set of parts or blocks within a single file. Obviously, this can be done at the body level, but if you open up the manager dialogue, you’ll see a list of bodies, planes and sketches. These are given default names, but can be easily renamed, by swiping the entry to the left. You can also delete it or zoom it into the window. This window also allows you to group together bodies into folders, which act as informal subassemblies or complex mass models.

Data export So how do you get your data out of September / October 2020

Software

Shapr3D? This is perhaps the most surprising part, considering the nature of the system. With the Pro version, you’re able to export your data as a Parasolid file (either X_t or X_b), STEP, IGES or OBJ. There’s also an STL export option, too the only export option, in fact, in the freemium version. You’re also able to export a basic 2D drawing from the system as a DWG or DXF file that includes all of the dimensions you’ve placed (and locked). There are also some nice screenshotting tools that remove the UI elements and might be useful for sharing with a colleague or throwing into a presentation.

In conclusion Over the years, a number of 3D modelling-adjacent tools have popped up on the Apple App Store, only to quickly disappear again quite quickly. Why? The answer is that unless a user really understands upfront what they’re doing with the platform, and the various interaction

methods that are not only supported but also expected, it’s very likely that the system will make little sense to them. I’m delighted to say that the Shapr3D team has taken a very different approach. Its focus on combining finger-based interactions with the more precise input offered by the Apple Pencil makes complete sense. If you’ve used a direct modelling system such as SketchUp before and are familiar with its modelling techniques, then you’ll be able to jump right in. If not, then you might need some time to get your head around the workflow. There are a few tutorials that show architecturally focused workflows, but the bulk of the tutorials are for mechanical design – they’re equally as useful for learning the ins and outs of the tool. If I had just one tip to help you get up to speed, it’s to consider this as a conceptualisation and 3D thinking tool, rather than a fully featured 3D design system. You just need to forget about being

super-precise and building complex models. Instead, just sketch, hack, slice and experiment and see what you get. It’s also worth considering Sharp3D purely from a workflow perspective. If you already have an iPad as part of your workflow and day-to-day work toolset, then you’ll probably be receiving CAD geometry in your email and/or via file share. Shapr3D allows you to view those files using robust Parasolid-based tools and potentially make very quick edits to them. Just the ability to view is useful. If the Sharp3D team also built in a few mark-up tools, that would make the app even more useful. If you’re curious about what this system can do, download it, get yourself an Apple Pencil and give it a whirl. There’s literally nothing to lose. You’ll find a system that lets you sketch out a quick model, try out an idea, and see what you get and it could quickly become an important step in your conceptualisation and ideation process. ■ shapr3d.com

Architectural design & the iPad: what else is there? To review Sharp3D, I invested in a more up-to-date iPad. To be frank, I’d stopped using these devices after their first generation, for a number of reasons. But it turns out there’s been some wonderful work over the intervening period. The new iPad Pro is a great example of the build quality that Apple offers. The Apple Pencil is really something else. For those who have been using a lagging stylus and become accustomed to working around parallax problems resulting from poor calibration of pen input devices, it’s a refreshing step change. The Pencil 2, in particular, with its magnetic attachment and wireless

charging is practically a miracle. (On the subject of charging, I’ve gone fully USB-C of late, so having the iPad use the same connectors makes life a lot easier, should we ever start travelling again). It’s also worth noting that multitasking on the iPad is vastly improved, particularly using window-in-window or split screen. It may take a few minutes to work out how to do this, but it makes working with multiple applications much easier. The other thing that impressed me about the standard device and software set-up is the Sidecar application. If you’re a desktop/ laptop Mac user, this lets you view your main screen on the iPad as a second screen. In these days where we’re all trying to work efficiently from home, that’s really valuable (not

least in terms of space-saving), especially if you’re missing your office-based multi-monitor set-up. If you’ve seen Astropad for the iPad/Mac, it’s like that - but being native to your hardware, it doesn’t cost you £10 a month to use. However, Astropad has a few benefits in terms of control and there’s a client application coming soon that would let you use your iPad as a companion, pen-enabled device with Microsoft Windows. Exploring the App store Since I had the iPad in hand and the kids hadn’t managed yet to steal it to play AR games, I figured now was a good time to explore what other applications for the designer and engineer it could run. One system I was keen to try out was Procreate for digital sketching. While I could wax lyrical about how smart Procreate is, how the drawing experience, brush development and user experience is wonderful, the simple fact is that it costs just £9.99 no subscriptions, no ongoing license fee. That’s a ridiculous bargain, especially compared to the cost of a license for Adobe’s Photoshop or Illustrator. If you’re exploring Procreate for design purposes, then I also highly recommend the Procreate

brush sets from Spencer Nugent, available at sketch-a-day.com. Morphilo’s Trace application also has to be a front runner. While it’s a sketching app, it has some serious tools for the architectural designer – import and scaling of plans and maps (even direct from google maps), AR tools for perspective and much more. Considering it’s $17.99 for a professional license for a year, that’s another bargain that’s worth exploring (there’s a freemium version too). Another product to consider is the venerable SketchBook from Autodesk - one of the first sketching systems and still one of the best. Beyond sketching The iPad Pro isn’t just for sketching and modelling - the 2020 model features built-in LiDAR scanning capabilities and mobile mapping startup Sitescape is developing a reality capture app to take advantage. The software allows users to to create dimensionally accurate point cloud datasets that can be used for progress monitoring, documentation, and remote site access/collaboration. According to the developers, accuracy is said to be around +/- 1” for linear measurements, while the max range of the LiDAR sensor is 15 feet.

For example, components with identical properties can now be found in a single click 2 Visualisation of selected data has been vastly improved. Objects can now be easily highlighted in the model, either by making the rest of the model transparent or switching it off entirely

type, system classification and so on, you can just type in the classification you want, and Revizto will automatically display which group(s) it comes from. It essentially means you can reclassify the order in which objects are grouped. For example, simply by typing ‘system’ and clicking the relevant fields, you can now quickly pull out all the components in the model, or those on a specific level, whose system classification equals, for example, either domestic cold water or domestic hot water. Of course, in large projects this could still bring up thousands of objects, so if you want to search in a particular room, level or building, you can also narrow things down by creating a 3D section box that focuses on a specific volume inside the model. Search sets can be saved, so common searches don’t have to be redone from scratch. They can also be shared with the team. The results of any search, complete with object data, can also be exported to Microsoft Excel, which could be used to define basic quantities. For example, to quickly tot up the total length of a specific type of steel column. Unfortunately, it’s not yet possible to do this within the software. As you’d expect, when importing BIM models, Revizto automatically brings over all of the object data. But, of course, not all of that information is relevant, so you can now set up a list of favourites. Once an object is selected, all of the most important information appears at the top of the list in the object tree. This focused data can even be seen when hovering the cursor over an object in the model, giving you much quicker access to object data without having to scan the property panel. A construction www.AECmag.com

manager, for example, could set up favourites to show the volumes or grades of concrete, and have different favourites for different workflows.

Custom data It’s now possible to add custom data to objects within Revizto and then, of course, use that data to create custom searches. It means Revizto can be used to track a lot more information than it previously could, opening up many new use cases. On a construction site, for example, it could be used to track whether or not something has been installed or inspected, and on which date. In theory, this could even extend to phasing information, allowing Revizto to be used as a rudimentary 4D tool. In the design phase, custom properties could help confirm that an engineer has checked and approved a section size change. All of this data can be thematically displayed in the model. It could be as simple

as green equals yes, red equals no, or something more nuanced. At the moment, custom data can only be viewed inside Revizto, but longer term, the development team is exploring the possibility of feeding that data back into the original BIM model, which would close the loop.

Performance Revizto is multi-platform and runs on Windows, MacOS, iOS and Android, on laptop, desktop or tablet. The performance and specs of these machines can vary dramatically and when you start working with multiple 3D models, it’s very easy to run out of memory, and for the system to grind to a halt. This is particularly true for those using Revizto on tablets which tend to have limited memory. In Revizto 4, while it was possible to ‘hide’ models, which would reduce the load on the CPU and GPU, the model would still be held in memory. With Revizto 5 individual models can now be September / October 2020

completely unloaded from memory, so, if you’ve got models that you don’t really need to be turned on all the time — MEP, architecture or specific buildings, for example — then simply switch them off. It’s not just through model management that Revizto 5 can free up memory. The new release also uses significantly less memory for tracking issues. According to the developers, version 4 could easily use up 1.5GB for 7,000 issues, which is pretty standard on a project. For the larger projects, where you might have 30,000 issues, this could swell to 6GB. In the new version this memory footprint has been significantly reduced, with 7,000 issues only using 100MB, which of course, will free up space for larger models.

authoring software and correct it. This not only took time but could be particularly challenging if the model came from a third party. With the new version, it’s now possible to change the location of a model within Revizto itself. This also extends to 2D/3D overlays, so if you bring in the 2D drawings from your BIM software, they will automatically be transformed as well.

Raising issues The fundamental part of Revizto is issue tracking and the new release refines how issues are raised. Issues are now directly attached to an object or objects, whereas previously they were just placed in the general vicinity. This could lead to ambiguity when

ticularly groundbreaking in Revizto 5.0 — the team has simply fixed an issue where ghost points might be left behind when creating sections. However, there is some useful new functionality coming soon, which will allow users to measure point clouds. For example, you might want to quickly measure between a pipe and a wall to check there’s enough room for maintenance.

Conclusion

It feels like version 5.0 is a pivotal release for Revizto. It might not come with headline grabbing features but don’t underestimate the importance of giving users more control over the data. Rather than having to rely on the model to drive the issue tracking process, users can let the The new focus on data opens up possibilities data do the work for them.

Interview

A Q&A with Enscape Greg Corke caught up with Enscape’s new CEO, Christian Lang, to talk BIM objects, issue tracking, RTX ray tracing, collaborative VR, point clouds and what the future holds for the popular real time visualisation tool Greg Corke: When we first looked at Enscape in 2016, the quality of the rendering was good, but nothing special. Now it’s gone to quite amazing levels and you also have Nvidia RTX ray trace rendering technology built in. How has that changed the way that your customers are using the software in their workflow?

And where does that leave the traditional arch viz ray trace rendering tools?

CL: Definitely. As you were saying, in many, many cases the visual quality is more than good enough for what the architects need when they present to a customer, when they use it for the design development, for Christian Lang: I personally design reviews, absolutely. believe it’s not really changHowever, I think there is ing the way the customers still a kind of a legitimaare using the software.

GC: Since the 2.7 release, objects can be selected in Enscape and their associated BIM information displayed. This is great, because I know your customers have been asking for that for ages. Now you’ve delivered, what feedback have you had and how has it changed the way your customers use the software? CL: The feedback we are getting is, it’s a good first step. However, customers always want more. They now want to have it in the standalone version, they want to have it in VR. So, it’s the first step into that direction, and more to come. GC: So, you can only access the BIM information if you’re connected to your BIM authoring tool? CL: Correct, you have to have the connection. GC: Now you’re on to version 2.8 and one of the most exciting developments is this new focus on design /review. You now have tools for annotation and issue resolution through the integration with cloud-based BIM collaboration platform BIM Track. This takes Enscape beyond its core remit of real-time rendering. Can you explain how this works? www.AECmag.com

19/09/2020 07:28

CL: The new annotation feature allows you to store issue trackers in the Enscape scene. So you can set states, you leave comments there for other team members, you’re getting an immediate overview of the progress in the project. The Enscape rendering is automatically added to the annotation. The discussion points are saved in the CAD project, then it can be exported in BCF [BIM collaboration format] or it can be synced with BIM Track. And especially this last part. That’s where the information throughout the whole design, you can leverage that full feature set and the interface of BIM Track with your Enscape visualisation without the need to export or import files. What’s interesting about [the integration with] BIM track is that it really provides for the industry (for the first time ever I think) a collaborative workflow in a fully photorealistic rendered model. So, you can see light and materials and textures and get a feel for the design that you just couldn’t have prior to 2.8.

GC: [smiling] That’s not specific to Enscape, of course, but because the GPU requirements of Revit are so small, has that been a barrier to adoption? For you to get Enscape on every single desk of every single Revit user, for example, they’re going have to update their hardware. CL: Not that I’m aware of. I think it’s exactly the opposite. I think that the customers appreciate that with Enscape they can even use not the highest performing hardware. Enscape is already optimised in a really good way that it can be used on a slower machine. And if they really want to have the high, high visual graphics, then maybe it’s just one machine they have, where they render the final kind of image. GC: Enscape was a pioneer of architectural VR. It was amazing how it was so seamless, while all these other tools were going through this long process of exporting and optimising BIM models. How are your customers using VR, and how has that changed over the years?

GC: Enscape loves powerful GPUs... CL: [laughing] Show me any real time visualisation software that does not love powerful GPUs. www.AECmag.com

p34_35_36_AEC_SEPTOCT_Enscape STRIP AD.indd 35

CL: I can just talk about one customer I met, where I had this specific conversation two weeks ago. The customer told me that they are using it in the same way they

would do a design review or a design development session. So, it’s kind of integrated in their design meetings, where they have questions or they want to show something if they have a topic they want to discuss, then they integrate it into that, but it’s not really fundamentally changing the way how they do the design reviews. It’s just another tool that they use. GC: So, at the moment, people are using it as a solo experience? So, if you were doing a design review in VR, you’d have to literally share a headset to get that done? CL: Yeah, exactly. GC: Are there any plans for collaborative VR? CL: The only answer I have is it’s on our radar. But I think the moment when we can offer something to the customers, and if they can use VR in a collaborative way, I think that can be a game changer when it comes to how they use it in a design meeting. Because that’s then when you also have the chance to involve someone outside of your company, right? Again, we have it on our radar, but obviously I can’t talk more with regards to that.

Interview 1

GC: Because of how easy it is to go from BIM to VR with Enscape, are your customers using it day to day - to literally jump in and out of VR? You’ve got a VR headset on your desk, you’re in the design process, you just want to check something, so you hold the headset up to your head to get better understanding of scale, and then you go ‘right OK, that’s great, or maybe I can change this or change that’. Are your customers using it in that way or is it more for design review? CL: It’s both. It’s while they are working at their desk, and it’s as part of the design review process. A really interesting story that came out recently about VR in preconstruction, where an architectural office actually invited the fire marshal and the building inspector and health inspector all in, for pre-construction to do their inspections. That’s another use case, beyond design review.

GC: Point clouds seem to be going crazy in AEC at the moment. Some CAD tools support them to various different degrees of capability. Enscape doesn’t at the moment. Is that something that you’re looking at? CL: Well, the same here, it’s on the radar. [In order to support point clouds] we need to go deep into the core product, so into the programming code and things like that. So, it’s on the radar, absolutely. By the way, we see that as well - point clouds and the explosion of that in AEC is becoming a topic. But we will see how we can support that, if we will support that. Right now, it’s completely open. GC: What’s Enscape’s long-term vision? CL: As you can imagine, this is of course a big question. What I can tell you is that, typically, I’m very much ‘outside in’ driven. And this is something that I’ve already figured out here at Enscape where I think we will become better — and this is really listening to our customers and involving the customers much more in the planning

of the future of Enscape. And this could even go beyond pure real-time rendering. But at the end of the day, what we are doing here, we are supporting the workflows of the customer. This needs to become the number one, or rather, this is the number one key theme for Enscape. I would love to become mission critical to customers. In our industry, there are still cases where we are ‘nice to have’ and this is changing slightly, but I think the future of Enscape is definitely in that direction.

Data ownership in a collaborative construction industry If a digital twin – or in the future, National Digital Twin and smart cities – is all about connected data ecosystems, what happens when data ownership and management are brought into the equation? Who owns the data, and how do we ensure the information can still be accessed in 10-30 years’ time. Stuart Bell makes a case for greater clarity around data and accountability, stressing the need for companies to be clear on whose role it is to maintain it.

he construction industry is highly complex and slow to change. With the industry facing skills shortages and an aging workforce just as the country needs critical infrastructure investment to boost the economy, the ways in which we design, procure and construct are under pressure to evolve. For the industry to confront these challenges there is a general agreement that the way in which it works needs to change. A culture of genuine collaboration and the sharing of information must happen, and digital technology could be the answer. Digitisation is helping project teams and asset owners drive efficiencies through more effective modelling, design, procurement, mobilisation, construction and operation, yet amongst this there is a great deal of confusion as to who owns data. These issues should be addressed at the earliest stage of the project, within the contract along with any interoperability expectations. Generally, as it is the client that is procuring the information, they must ensure they specify responsibilities or have the resources and knowledge to manage their model to maintain it. If we look into the not too distant future, it may will be that autonomous systems and robots will be using it for operations and maintenance. Document www.AECmag.com

Comment

noticed the significant inefficiencies in the industry, and suggested digitalised processes and standardisation around common naming conventions would allow 40% of construction project costs to be saved. Whilst ideal in theory, in reality it was problematic to force the industry to take ownership of a 40% cost saving, especially when the industry is perpetually working off tight margins. To alleviate the burden of this mandate the industry cut corners, which had all sorts of negative implications on building delivery and quality.

Where outsourcing becomes a problem If project and asset data is fragmented and then for some reason compromised e.g. the principal contractor falls into administration, all of the project information which is hosted and managed is locked-in, and clients and other project parties are locked out from accessing it. The onus is then on the asset owner (client) and not the contractor to retrieve and re-procure the thousands of datasets from different parties involved on the project. As an alternative to re-purchasing the data from the design team or supply chain, the built asset may need to be re-surveyed to establish the required data, and this can incur further costs. What is lacking here is client ownership of a clear, accessible audit trail to ensure all transactions throughout a project and asset’s lifecycle are maintained. Rather than outsource the information management service, wouldn’t it be better for the asset owner to insource the data so they have access to the information and audit trail? Can pressures on the supply chain be lightened by providing a clear destination for data drops and information handover?

What are the alternatives? Most organisations procure information differently and have multiple systems with different users managing data, and these are some of the main reasons why data can be so fragmented. Often it is better to have a single version of the data in one place to be accessed by many, as it avoids duplication and ensures each piece of data is in its truest and trusted form. Providing a single version of the truth for all project and asset data, a project and 40

asset information management system or common data environment (CDE) enables information to be accessed and shared by all parties throughout an asset’s lifecycle. A CDE enables all parties to securely communicate and collaborate on a structured workflow basis whilst simultaneously continuing a robust audit trail. It might be worthwhile to mention that on most major projects the Tier 1 organisation is often the prime and information management lead, provisioning the CDE on behalf of the client, ensuring project information is delivered, assured and approved prior to formal handover. With all parties in the chain managing and exchanging information in a CDE, there will never be a missing link. With a clear audit trail of all asset data, the access to and provenance of all records is maintained. This means asset owners can question and query a trusted data store to answer everyday queries about assets in their estate at any stage.

Make it contractual If you use an office analogy, a CDE is essentially an electronic filing cabinet housing copies of audited information. Yet, asset owners have to be explicit in which information the CDE must contain, and must outline their individual requirements in the contracts to maximise the CDE’s performance.

As an asset owner, at the start of the contract you will procure both the asset and a level of detail of the digital information. A well-written contract must be produced as this will act as a reference point for what the contracting teams have to deliver. It will also be a vital archive if and when maintenance upgrades are required. With a contract which clearly outlines requirements, there will be a greater understanding of the purpose of the information and who owns it. When asset owners come to operate their buildings, this record will enable them to make proactive decisions, instead of turning to their supply chain to acquire information which should belong to them. An asset-owned CDE is part of the change towards better data ownership; creating an unbreakable chain where every piece of data regarding a built asset can be retrieved at any time. With data fragmentation and unreliability key concerns for the construction sector, surely the adoption of a system which provides one version of the truth across a building’s lifecycle is a valid solution to ending any disconnection?

Case study

4D: in the driving seat BIM Academy’s Peter Barker explains how 4D modelling helped deliver the complex A19/A1058 Coast Road junction upgrade project and explores future trends we can expect to see in highways design

he A19/A1058 Coast Road junction is one of the busiest road intersections in the North East of England. In 2016, work started on a major upgrade to combat congestion and improve consistency in journey time. The £75m improvement project was a part of the UK Government’s £15 billion roads investment programme, which aimed to foster economic growth in the North East as part of the Northern Powerhouse initiative. The challenging project required the installation of a three-level flyover / underpass and roundabout. To help plan construction and support the critical need to maintain traffic flow throughout, while minimising disruption, it was one of the first major highways infrastructure projects in the UK to utilise 4D BIM.

Construction in a live environment In 2017, BIM Academy was approached by the JV supporting Highways England to work on the project. This was initially as a digital construction expert to assist in achieving compliance with the UK 42

p42_43_AEC_SEPTOCT20_highwayV2.indd 42

Government’s mandate for BIM Level 2, but the role quickly expanded to focus on delivering greater practical value throughout the two-year project and helped to bring the project in 31 weeks ahead of schedule. Design team WSP and construction JV partners Sisk/Lagan worked with BIM Academy on this incredibly complex project. The size and scale of the upgrade were of course a factor, but the real challenge lay in the fact that the junction is a major regional component of the Strategic Roads Network (SRN) – and had to remain active throughout the course of construction. Working in a busy, and potentially hazardous live environment involved heavy restrictions and constraints on the construction process, posing significant challenges to the timescale and budget of the project – and perhaps most importantly, the safety and logistics considerations of improving road user experience with minimal disruption to transport routes. An innovative solution was required to enable the project team to meet the safety requirements of a live environment,

while still delivering a high-quality end result. As well as tackling appropriate standards and protocols, providing guidance to design and construction teams, BIM Academy brought forward a proposal to use 4D technologies on the project.

Introducing 4D The idea was to link programme planning tools to the existing 3D digital design and terrain models, in order to more clearly visualise and communicate the construction sequence and potential barriers. Reviewing and assessing the potential construction sequences in a virtual environment became one of the project’s standard design steps before anything reached the live environment on site. Using programmes such as Revit, AutoCAD Civil 3D and Synchro, the team was able to visualise and analyse how construction sequencing would affect the live environment at any given time, by creating a visual dynamic sequence from the 3D model and planning software. Not only did this approach aid in the planning coordination and buildability, it www.AECmag.com

17/09/2020 16:09

also significantly improved design of temporary works, which reduced the risk and negative impact of the project as well as streamlining and optimising the end solution, which incorporated smart traffic monitoring systems (STMS) and automated signalling, in a nod to future highways technologies. The end result of the approach was that the project team was able to visually communicate and plan activities in the context of time and space, taking account of resources, procurement and spatial constraints. This created the thinking space – and provided the data – to assess alternative approaches to site layout, scheduling and logistics during the construction phase, providing a number of alternative options for contractors to assess all risks and opportunities, and make fully informed decisions around construction costs and sequencing. This innovative approach to ‘optioneering’, as well as access to new and better data, was influential in the logistical improvement of the A19/A1058 Coastal Road project – so much so that 14 months were cut from the original estimated 42 month construction pro-

gramme, saving over a year of road disruption and a huge amount of cost.

The future of highways design This of course raises the question – should this approach be applied to all major highways improvements moving forward? This optioneering process allowed the contractor to assess all risks and opportunities. The future of highway design is certainly focused on leveraging digital tools to assess and optimise alternative solutions whilst factoring in legislative design standards. There are also other future trends we can expect to see in highways design. Systems such as Motorway Incident Detection and Automation Signaling (MIDAS) are being developed and implemented by Highways England right now, as a distributed network of traffic sensors. Radar technology and magneto-resistive wireless sensors are also being trialed and are designed to alert local regional control centres (RCC) of traffic flow and average speed, as well as automating variable message signaling and

advisory speed limits with minimal human intervention. Improving traffic flow with the use of digital technology is something BIM Academy definitely sees being introduced in more and more projects such as this one, introducing the ability to proactively predict and control traffic with all of the consequent benefits on safety, environmental impact and user experience. Highway design based purely on design of the physical infrastructure can be risky. Introducing a combination of sensors and 4D modelling is the way forward in smart infrastructure design, helping to measure the impact before it happens, and allowing for a smoother, less invasive, greener – and cheaper – project. In the future, I believe we will start to see trends including the increased adoption of in-vehicle technology. The consequent reduction of roadside tech will follow, seeing the introduction of so-called ‘Naked Roads.’ We expect to see this concept escalating over the next two years as the government presses ahead with initiatives promoting vehicle-centric intelligent technologies. ■ bimacademy.global

Leica BLK2GO As demand for more portable, rapid scanning solutions increases, Leica has unleashed its first, handheld SLAM device, the BLK2GO, together with a new cloud-based visualisation and collaboration platform, HxDR. Martyn Day reports

he laser scanning market tends to move glacially. It’s an old and mature technology, and revolution is not in its nature. There have been some glimpses of excitement over the years — when Faro brought out a £20k scanner that could fit in an aeroplane carry on, or when the major CAD software developers built point cloud engines into their core BIM tools, but critical mass has never been achieved. Then in 2016 Leica did something atypical - it brought out the ridiculously gorgeous £15k BLK360. The compact laser scanner was ideal for scanning interiors and the device was tied into the equally innovative Autodesk Recap on an iPad, but just as we thought this might be a real catalyst for change, no other firms joined in at that price point. Laser scanning continued to stubbornly stay out of the reach of the masses, compounded by the fact that Leica couldn’t make enough of the BLK360 to satisfy the demand. Now Leica has a new product and its styling looks like it’s from the future. Could this be the product that finally democratises point cloud capture?

The first thing that has to be said is that Leica must be employing an incredibly talented industrial design team. Both the BLK360 and the new BLK2GO are the most beautiful looking scanning devices that have ever been made. Even if you didn’t know what the BLK2GO did, you’d still want one and would want to hold it and show it to your friends like it was a Fabergé egg. The BLK360 is a static laser scanning device for rapid point cloud capture over short distances. In contrast, the new BLK2GO is highly portable and adapts SLAM (Simultaneous Localisation And

Mapping) technology, which was originally developed for robots and autonomous vehicles. There is a price for this liberating scanning technology over a standard tripodmounted laser scanner and that’s accuracy. SLAM point clouds are typically accurate to around 20mm, which is still incredible when you consider a site that would take a day to capture through traditional methods, might be done ten times faster with a SLAM device. However, this limitation means there will be times when the BLK2GO isn’t appropriate compared to traditional surveying. Leica’s BLK2GO has been designed to be as simple to use as possible. Featuring one button operation, it wirelessly links with a Leica iPhone app, so the operator can see in real-time the data it gathers in both 2D and 3D. The device features enough internal storage for 24 hours of scanning (compressed), 6 hours uncompressed and has an exchangeable battery which lasts for approximately 50 minutes. The range, however, is not huge — from 0.5m to 25m — but this is a SLAM device so your feet can do the work. It combines a 420,000 pts per second laser scanner with a 12-megapixel camera, together

with an additional 3 camera panoramic vision system. Leica states that the BLK2GO can go down to 6-15mm accuracy and to achieve the highest accuracy, its case can be turned into a base for static scans. While the iPhone app is a useful tool for onsite feedback, the BLK version of Leica Cyclone is recommended for importation and scan clean up. Everything from the design of the device, to the ease of one button operation and the speed make the BLK2GO a highly desirable surveying and data capture tool. The nature of the scanned data makes SLAM scans look a bit different to traditional point clouds, with more visible banding in the variance of point cloud density, but this does not impact the quality of the data captured. So what’s the downside? Well, while this technology is something that everyone in the industry would absolutely love to have, it does cost around £40k a pop. For a surveying firm, this is a no brainer — it has the potential to deliver a huge productivity benefit. However, as far as liberating and democratising point cloud capture within the industry, I am afraid this beautiful device is not going to be the one to make that happen. The BLK2GO is very much aimed at the traditional surveying firms or, as Leica told us, Hollywood, as a number of films have used the device to capture sets and scenes between takes. It will certainly lead to quicker, less obtrusive, more frequent scans and might bring the cost of data capture services down.

The big picture Teradici, with its PCoIP protocol, has always targeted the most demanding users of remote workstations. Now it’s aiming even higher, delivering ultra-high image quality at 4K and 60 frames per second. Greg Corke caught up with Teradici’s Ian Main to find out more

ith 15 million end points using its PC-over-IP (PCoIP) display protocol, Teradici has established a strong footing in high-performance virtual desktops. The company places a big emphasis on high-fidelity ‘lossless’ image quality that preserves every little detail when remotely accessing graphics-intensive applications like 3D CAD, visualisation and visual effects. The PCoIP protocol is widespread. It is used by VMware for its desktop and app virtualisation software VMware Horizon (although, more recently, VMware has developed its own called Blast Extreme). It helps Nutanix deploy workstations and virtual desktops in on-premise or hybrid cloud environments, and it can be found in the public cloud through Microsoft Azure, Amazon Web Services, and Google Computing Services. “Our software product is available as a marketplace instance and along with reference designs, is in all three public clouds,” confirms Ian Main, Teradici’s technical marketing principal. Teradici’s PCoIP technology is also being used extensively to deliver 1:1 connections to rack workstations from Dell, Fujitsu, Boston and many others. There are plenty more doing similar for desktop workstations. More recently there has been a lot of interest in PCoIP from smaller managed service providers who are looking to provide remote solutions for their graphicshungry customers through GPUaccelerated cloud workstations. Main explains that service providers are becoming an increasingly popular choice for customers that want to outsource everything. While public cloud means firms don’t need to manage physical workstations, they still need to have some 46

According to Main, this

has enabled Teradici to dramatically improve the user experience. It has gone from being able to deliver 30 Frames Per Second (FPS) at HD resolution to 60 FPS at 4K or 30 FPS at 4K with dual displays. “PCoIP Ultra is a single codec that takes you all the way from lossy to lossless, so we can adapt to the network at any quality level. You get a really fluid experience, no matter what your network bandwidth is,” says Main. Main adds that firms that use Teradici technology on premise will be able to operate at a very high image quality, compared to the other remote computing protocols. “Our default quality is significantly higher and then we can go all the way up if the network can take it,” he says. Teradici is not wholly reliant on the CPU though. Working closely with Nvidia, it can now offload the encoding to the GPU using Nvidia’s NVENC encoder. Teradici is also working on optimisations for AMD GPUs. “You can choose between using the AVX2 for that high quality, up to lossless, encoding, which is what our protocol was renowned for, or for the bandwidth efficiency use cases, or when you want to avoid using CPU encoding at all, you can switch to NVENC encoding,” says Main. When this magazine first tested PCoIP technology in 2014, everything was done through hardware and Teradici made a big noise about the benefits of using dedicated silicon for encoding / decoding. However, much has changed since then, as Main explains. “Ten years ago, an encoder would have absolutely saturated the CPU, but I now have machines here with 24 cores. I can dedicate four or six cores to PCoIP encoding for very high performance use cases and the rest are for the [application] workloads. Now, there are a few occasions where you want all the cores for rendering, so then you can use NVENC.” Teradici has not forgotten about its

remote workstation cards which can now support 4K at 30 FPS, but Main admits that PCoIP hardware is really at the end of its lifecycle and the focus is now on software going forward. “As HDR and 10-bit and all these new resolutions and formats come on board, those will all move forward in the software regime,” he says. This shift to software is also happening on the client side. “Historically, our zero client was very high performance because you have a dedicated silicon decoder, and our software client was almost like your secondary axis,” says Main. “But over the last year, and as our overall focus shifts to software, we are needing to get that very high performance on Windows, Linux, and Mac — tablet and mobile clients as well.”

The power of the pen

ed in one of two ways: ‘bridged’ or ‘local termination’. With ‘bridged’, all of the pen data is sent to the driver on the remote workstation, which processes things like pressure, and then sends the response back to the local device. This works fine over LAN (<25ms) but as soon as latency increases, which is typically the case with cloud, the screen can start to lag behind.

Teradici has traditionally worked well with input devices, including the 3Dconnexion SpaceMouse and Wacom tablets and pen displays, which are increasingly being used in architecture. In the early days, Wacom devices were best

Moving to the cloud The availability of public cloud instances is growing fast, but Main believes that hybrid cloud will continue to be the favoured approach for some time. In addition to firms wanting to make the most of existing on premise hardware investments, there’s also plenty that ISVs could do to make their software fully compatible and optimised for cloud. Teradici has been working to make it easier for firms to manage local and cloud workstations together through an integrated service called Cloud Access Manager, part of Teradici Cloud Access Software. “[It] does the connection management and connection brokering for on-premise workstations and workstations on any three, or all, of the public clouds under a single management environment,” says Main. “We’ve been spending a lot of effort on that and, of course, features for brokers take a long time, so the adoption was quite slow because we didn’t have key features like groups and pools and things,” he says. “We always had that connectivity across

supported through Teradici hardware at both ends, but the company has now expanded the capabilities of its software, so users can get a better experience when using Wacom devices on high latency networks. Wacom devices are support-

public clouds, and it includes the security gateway component too, so that allows users to be either on site or off site in all these cases.”

Conclusion Teradici has carved out a niche for itself with its PCoIP remote graphics protocol, focussing on high-quality, lossless image compression. While this has traditionally appealed to those in media and entertainment, it’s also extremely relevant to design, engineering and architecture. Super sharp linework and text is important for CAD, while high-frame rates at 4K resolution are a big benefit for realtime visualisation. Indeed, Teradici has been a key technology partner for Nvidia Omniverse, a new platform technology that brings together architects and other stakeholders in a visually rich, real-time collaborative environment. The challenge for Teradici is how to effectively communicate these benefits to its customers. In the public cloud, PCoIP is generally offered as an option, with most providers having default protocols, so firms would actively need to make the switch. For those using smaller service providers like Avatara and BOXX Cloud Services, education is less important as PCoIP is only one part of a complete managed solution. While Teradici’s main focus is on cloud or on-premise virtual machines, it still gets good business from adding remote capabilities to desktop workstations. Here, it faces increased competition from HP, which is finally making some noise about its RGS software (now rebranded ZCentral Remote Boost), which comes free with HP Z workstations. Meanwhile, there’s also Mechdyne, which recently partnered with Lenovo ThinkStations over its TGX technology. Microsoft RDP is also prevalent, but this is at the other end of the scale in terms of end user experience. ■ teradici.com

‘Local termination’ improves this responsiveness by adding a lightweight version of the driver, client side, which displays a local cursor. It means the user can instantly see lines as they are drawn, with the detail then filled in a split second later once it’s been processed by the full Wacom driver on the

remote workstation. ‘Local termination’ was first supported in the firmware of the Zero client but has now been added to the Cloud Access Software.

Lenovo ThinkPad P1 [Gen 3] For CAD on the go, this sleek ultraportable 15.6-inch laptop impresses, but it struggles a little to stand out from its predecessors, writes Greg Corke The ThinkPad P1 was Lenovo’s response to the ultra-portable 15.6-inch mobile workstations that had been flying out the doors at Dell and HP. This year’s Gen 3 model is more evolution than revolution, featuring the same chassis as the Gen 1/ Gen 2, but there’s still plenty for CAD users in search of a good balance of performance and portability from their mobile workstation. Stand-out features of the Gen 3 model include a new super-bright 600nit UHD (3,840 x 2,160) LCD display, optional LTE WWAN for mobile broadband and enhanced cooling. In terms of core specs, there’s a choice of 10th Gen Intel Core CPUs up to eight cores and 5.3GHz, a small improvement over the 9th Gen Intel Core CPUs in the ThinkPad P1 Gen 2, but the same choice of Turing-based Nvidia Quadro T1000 or T2000 GPUs.

Sleek & minimal The ThinkPad P1 Gen 3 is a stylish machine. It’s thin (18.4mm) and light (starting at 1.7kg) and comes with a new matt black ‘anti smudge’ soft-touch finish that significantly reduces marks from greasy fingerprints, a bugbear of the Gen 1/Gen 2 models. There’s an understated carbon fibre weave on the rear of the panel to show off the premium materials. Like its predecessors, the ThinkPad P1 Gen 3 has been designed to withstand (and is Mil-Spec tested for) cold, heat, vibration, shock, dust and other hazards. Built with a magnesium chassis, the laptop has a really solid feel to it: the hinge is firm, the display is rigid and the keyboard has very little give. All of this is trademark ThinkPad. The keyboard is seamless, so it blends in with the palm rest, but there’s no numeric keypad. There’s just about the right amount of travel on the keys, making typing a pleasure, a reminder of just how unimpressed I am with my 2019 MacBook Pro’s ‘butterfly’ keyboard. Equally, the glass touchpad has the perfect amount of resistance with full multitouch support.

On paper, the Core i9-10885H might have a 5.3GHz Turbo, but this is a theoretical maximum and in our singlethreaded Solidworks CAD benchmark, we mostly saw it hovering around 4.6GHz/4.7GHz, with very occasional bursts of 5.0GHz.

Review Gen 3 does run steady and maintained an all-core frequency of around 3.30GHz, even when rendering for well over an hour. Impressively, fan noise was quite acceptable and the chassis — the palm rest in particular — remained cool to the touch. Importantly, the P1 also performs well when running off battery, completing our render test in 442 secs, only a touch slower than the 397 secs it took when plugged into the mains. In the point cloud processing software Leica Cyclone Register 360, the P1 did well, but as this multithreaded application is heavily dependent on available RAM, it would have done a lot better if the machine was configured with its maximum 64GB. It imported and registered our 100GB test dataset in 3,843 secs, 28% slower than an equivalent 8-core desktop CPU, also supported by 32GB RAM. The Quadro T2000 GPU is a Max-Q Design variant, which means it’s clocked slower than a standard T2000 in a larger mobile workstation like the ThinkPad P15 or HP ZBook 15. However, it’s still perfectly adequate for 3D design work, particularly as most CAD and BIM applications are CPU limited so they can’t even take advantage of a more powerful GPU. 3D performance will likely fall short in real-time viz applications, not just in terms of processing power but also in terms of GPU memory (4GB), though this can be offset to some extent by dialling down the display resolution or increasing scaling. In real-time arch viz tool Enscape, for example, we got an unworkable two frames per second at 4K resolution, but this jumped up to 24 FPS when the display was scaled to 250%. But this means you won’t get the most out of the beautiful 4K display. Or, you could buy a FHD panel instead.

Ultra performance mode? When Lenovo first announced the ThinkPad P1 Gen 3, it made a lot of noise about a new Ultra Performance Mode that would allow users to dial up system performance as and when required, by effectively pumping more power into the CPU and GPU. Unfortunately, Lenovo ran into problems during testing and validation, which meant the system didn’t perform as hoped. As a result, for this Gen 3 release, UPM isn’t the market differentiator that Lenovo was aiming for. The company puts this down to the fans, which wouldn’t spin fast enough to take advantage of the new cooling solution. Lenovo told this magazine that UPM still offers some benefits in this current iteration, mostly during longer duration workflows, which may explain 50

its relatively high clock speeds when rendering. It added that it has already sourced a higher-powered fan for the next generation and the UPM design philosophy will continue going forward.

Conclusion The Lenovo ThinkPad P1 Gen 3 is an impressive professional laptop for CAD

on the go — powerful, thin, light and extremely well-built. It’s a great upgrade from a bulkier mainstream 15-inch mobile workstation, but if you already own a ThinkPad P1, then it’s a harder sell. An improved display and WWAN support will be important to some, but in terms of raw performance, it won’t be a huge step up.

When laptop processing power isn’t enough Mobile workstations, even slimline models like the ThinkPad P1, are perfect for CAD and pretty much offer the same performance as a powerful desktop workstation. But it’s for more demanding workflows like ray trace rendering, real-time viz, or simulation that laptops often fall short. Even models with more powerful GPUs like the ThinkPad P15 can’t truly compete and you’ll always be limited by an 8-core CPU and 128GB of memory. Some users get round this by having a meaty desktop in the office and a laptop for remote work. But, in this day and age, this is a bit of a luxury, and with Covid-19, the definition of office is becoming increasingly fluid. There is another way to do this and that is to give laptop users a boost with a remote resource. This can be done via the cloud, through ondemand access to a GPU-accelerated virtual machine, but this capability can also be brought in-house with an on-premise data centre solution. The Lenovo ThinkStation P920 Rack is a dedicated 2U rack workstation with dual Intel Xeon Gold CPUs, Nvidia Quadro RTX graphics and up to 3TB of DDR4 memory. The idea is that a user can remote into the machine from a laptop, and use its vast resources as and when required. This isn’t just for heavy duty batch processing. With Mechdyne’s TGX Remote Workstation software, it’s possible to remote into the workstation and use it as if it were a local machine, with full 3D acceleration. TGX Software works by compressing and sending the desktop pixels on the rack workstation to a receiver on the laptop where it is decoded and rendered. You get the best performance when using Quadro GPUs at both ends, but decoding can also be done on the CPU, so you could use a standard office laptop. We tested this remote graphics solution with the ThinkPad P1, connecting into a ThinkStation P920 Rack with 2 x Intel Xeon Gold 6246 CPUs (24 cores), 192GB DDR4 memory, an Nvidia Quadro RTX 5000 GPU and Windows 10 Pro. Getting connected is incredible easy — simply download the TGX client, punch in the IP address, user and password and away you go. Despite us being in London and the P920 Rack being in Raleigh, North Carolina in the US, the experience was excellent. In Solidworks, for example, a large assembly responded instantly to our mouse movements, with only a barely discernible lag. This was more

than comparable with other remote graphics testing we’ve done with other protocols in data centres in the UK and Europe where the latency is much lower due to the shorter distance. Impressively, we did this over WiFi 5, connecting to a 100Mbps Virgin home broadband. We had intended to plug straight into the router over Ethernet to minimise latency at our end, but there really was no need. We also connected over 4G, tethering the laptop to an iPhone, and while it felt a tiny bit laggy, it was still perfectly usable. By tapping into the power of the P920, we were able to significantly accelerate some of our more demanding workflows. In KeyShot, for example, it completed our render in 120 secs, significantly faster than the ThinkPad P1 (397 secs). We had a similar experience with the V-Ray NEXT benchmark with CPU rendering 3.28 times faster and GPU rendering 3.12 times faster. With complex simulation, we would expect the potential gains to be much bigger, as the P920 can tap into so much memory. Importantly, it also transformed our real-time 3D experience in Enscape, going from 2 FPS on the ThinkPad P1 up to a silky smooth 25 FPS on the ThinkStation P920, taking full advantage of the 16GB Quadro RTX 5000 GPU. This could be great for client presentations when high frame rates can make a real difference. Optimising workflows between the two machines will require careful consideration, not least how to share data effectively. Copying data from the P1 to the P920 was slow, bottlenecked by the 10Mbps upload speed of our home connection. Dropbox quickly become our preferred solution. Overall, the ThinkStation P920 with TGX software is an interesting way to address workflows with different hardware demands. You could give designers lightweight laptops for everyday CAD work, then on-demand access to vast GPU and multithreaded CPU resources as and when workflows dictate. Resources can also be shared by teams, to make things more costeffective, and software brokers used to manage access to large pools of machines. Finally, multiple users can also connect to a single remote desktop for a collaborative session. You only need to license the TGX software on the sender/host — the Receiver software is free. Lenovo is currently offering a free 120-day trial of Mechdyne TGX Remote Workstation software. ■ lenovoremoteworkstations.com ■ mechdyne.com
