Adding information to a BIM is hard ...we make it easy Consistent level of development in Building Information Modeling (BIM) is difficult to achieve. At Bricsys, we’ve applied machine learning to BIM workflows to simplify and facilitate the creation of high-fidelity building models. Adding information consistently is hard

Using Propagate to speed steel detailing

Adding information to a BIM in a consistent manner is a daunting task. Being able to continuously add level of development (LOD) is critical to the creation of a digital twin. Traditional BIM workflows do little to assist a BIM technician in managing LOD. It’s just too easy to add rich detail in one area, extract drawing sections from those areas, and leave the rest of the model at a reduced LOD. And variable LOD is generally acceptable until it’s time to extract schedules. Then, the weakness of an inconsistent level of development becomes glaringly apparent.

Let’s talk about connecting steel members and raising LOD across a model simultaneously. Consider a column-beam connection using an end plate and several bolts. We want to detail this connection once, inserting the end plate and the fasteners, and creating the holes in the beam web for the bolted connections. Once this process is complete for a single instance of the connection, PROPAGATE can do its magic.

A.I. can help At Bricsys, we leverage machine learning technology to assist you in managing a continuous increase in model LOD. The primary toolset for this purpose in BricsCAD® BIM is called PROPAGATE. It’s a tool that helps automate the process of adding data – “the information” – to a building information model. At the simplest level, PROPAGATE is used to copy details throughout your building model. It maps the details of a selected element to similar elements in the model. What does this mean? Anytime a specific detail is required / needed or usable in multiple locations in the model, using Propagate is likely the fastest way to make it happen.

The Propagate Workflow We’ve built five variants of Propagate to guide you through the workflow. Each of the five “flavors” were designed for specific use cases. This helps to keep the Propagate workflow clear and concise - e.g., when connecting steel members, cleaning up wall-slab connections, raising the LOD of a roof edge detail, or placing lighting fixtures, windows, air diffusers or columns on various surfaces in your BIM.

www.bricsys.com

The general workflow of PROPAGATE consists of two major steps: defining the detail to be replicated and choosing where to apply it. The first step is to simply select the base solids – the beam and the column. The next step is to select the detail objects, a.k.a. “sub-entities”. These are the elements that you want to PROPAGATE throughout the BIM. Detail objects can be solids, block references or even faces – e.g., a hole in a base solid can be propagated by selecting its faces.

Detail volume creation After you select the base and detail objects, PROPAGATE defines the detail volume, switches the visual style to X-ray and zooms in to the detail for verification. You can alter the detail volume as needed to accommodate target solids that are further apart, or the need to replace existing details with new details that are smaller than the original. Think about this for a moment – there is no need for perfect alignment of beams and columns throughout the model. Enlarge the detail volume to encompass the largest gap, and the elements will be joined properly throughout the entire BIM.

Let the A.I. do its magic… Once the detail volume includes everything that you want to PROPAGATE, choose where to apply the detail. The view will zoom out to show all possible locations for the operation and will flag each potential location with an icon that shows your options. As the user, you have full control over what

PROPAGATE does. Individual details can be toggled on or off; potential interferences are noted, and situations where multiple valid alternatives are possible are also called out. Make your selections from the A.I.’s recommendations and PROPAGATE does its work.

…and voila! Tens, hundreds or even thousands of detail increases will sweep across the BIM in seconds. In one fell swoop, PROPAGATE can raise the LOD of all similar steel connections from 200 to 450. Yes, it’s real. And it’s a Bricsys innovation that’s available today in BricsCAD® BIM. But innovation doesn’t end with PROPOGATE – it’s just the beginning. BricsCAD®, BricsCAD® Mechanical and BricsCAD® BIM include A.I. features that increase LOD, infer design intent, automate parameterization and reduce model size by detecting & instancing repetitive geometry. All in one multi-threaded, modern and cost-effective CAD system. Do you know BricsCAD®? If not, you simply don’t know what you’re missing.

he Ghent-based BIM and technical drawing ‘upstart’ Bricsys has released version 20 of its core design tools. Part of the Hexagon suite of companies since 2018, Bricsys develops an AutoCADcompatible drawing application, BricsCAD and a relatively new BIM solution called BricsCAD BIM. New features of this release include support for McNeel Grasshopper through a dedicated connection enabling geometry to be driven by the popular visual generative design solution. There is a new stair model which can create parametric staircases with just a few clicks. The real time rendering application Enscape is now supported. IFC support has been upgraded to export and import IFC 4.0,

which supports NURBS and meshes. The BCF format is now included to communicate model based issues with other applications. BricsCAD BIM has a unique approach to modelling. Architects can model with pure geometry and then have machine learning identify objects, such as walls doors and windows, applying the necessary IFC tags. v20 promises and more of that capability. Automatch will automatically match and complete BIM information which is missing. AEC magazine will have a full review, next edition. Meanwhile, HOK has just announced it will be looking at BricsCAD BIM as a Revit alternative and has also become a BIM Alliance Partner of Bricsys. ■ bricsys.com

S startup OpenSpace is using patent-pending, artificial intelligence to automatically create navigable, 360° photo representations of a building site. Construction workers attach a small offthe-shelf 360° camera to their hardhats and walk the site as normal, with OpenSpace passively capturing imagery in the background. Imagery data is then

uploaded to the cloud, where OpenSpace’s algorithms map the photos to project plans and stitch them together, creating a visual representation of the site similar in style to Google Street View. This data then accumulates over time, providing builders with a “time machine” that allows them to review site conditions as they were a day ago, a week ago, or years ago. ■ openspace.ai

NBS offers one click into leading CDEs sers of the NBS Chorus specification platform can now ‘instantly’ export a list of submittals from a specification in one click and import them directly into leading Common Data Environments (CDEs), including Autodesk BIM 360.

Tridify makes BIM models ‘instantly’ viewable online ridify has extended its BIM to XR Processing Service so BIM models can now be made ‘instantly’ available online and sharable via a web link. The new Web VR option automatically generates an interactive 3D model from an IFC file and makes it accessible via a URL, ready to be embedded on a web page, sent via email or text and viewable on a mobile phone. By sending a link to a 3D model instead of a file, users can publish/unpublish their models and manage their visibility, giving greater control over how the models are used. Tridify points out that models cannot be copied and intellectual property rights are better protected. The service is targeted at AEC professionals, but Tridify explains that the new option also creates opportunities for non-technical audiences. 3D models are easier to share internally, externally, with customers or consumers, on mobiles,

tablets, desktops or VR headsets says the Finnish developer. Tridify will also be providing various web viewers to enable a model to be shown in different ways to different user groups, depending on the end use and skill level. To make a model ready to view online, users simply need to upload an IFC file and click ‘publish’. No additional applications or programming skills are required, says Tridify. ■ tridify.com

Cloud platform ‘BIM, AI & big data ready’ apio Cloud is a new digital project management software from Copenhagen-based Optimise-International. The encrypted cloud-based platform is said to give construction companies secure access to analyse the reams of data generated from robotics, drones, BIM and industrial IoT sensors. The system uses Artificial Intelligence (AI) and machine learning to analyse data. According to the company, this helps construction companies make

more accurate decisions – an area which has traditionally been reactive, rather than predictive. Dynamic dashboards and a multilanguage interface are designed to make collaboration and analysis easy. Each project team can view a unique set of dashboards, specific to their KPIs and contract deliverables. Kapio Cloud is a pay-as-you-go, SaaS model, where contractors, construction firms and clients only pay for what they use. ■ kapio.cloud

t may come as a surprise, but in the late 1970s and early 1980s there were many architectural and construction firms in London using 3D computer modelling systems to generate plans, sections, elevations and drawings of their buildings. Software such as BDS, RUCAPS, Sonata and GABLE, running on mainframe and minicomputers, were the first BIM solutions. Compared to the tools of today they may well appear rudimentary, and they were certainly very expensive, but they were actually very advanced for the time. It goes against the stereotype that the industry is not very progressive in adopting new technologies and applying them in practice. Then came the relatively low-cost IBM www.AECmag.com

‘‘

At some point soon there will be a dramatic change in workflow or output, that software developed decades ago can no longer address just by adding some new features

’’

PCs in the 1980s and, together with cheap drafting software, such as AutoCAD, most of these mainframe dinosaurs were relegated to the scrapheap, and the architectural design world went ‘a little flatter’. However, none of the original concepts died, living on in ArchiCAD, AutoCAD AEC, Architectural Desktop and then culminating in the arrival of Revit in 2000. In those early days of Computer Aided Design (CAD), technology changed at a snail’s pace. We would literally have years in between software releases and meeting someone with a graphics card capable of a massive 256 colours was once a truly rare event! Today’s AEC firms are facing a very different landscape: evolution is built in, software www.AECmag.com

p12_13_15_16_19_21_AEC_SEPTOCT19_generation_game.indd 13

upgrades and updates can come every six months or less, hardware can now mean VR headsets and software can be online as a service. Design IT directors of large AEC firms have to stay up to speed with what’s coming, while managing what they have and preparing for what they will have in the future in order to remain competitive. Of course, all this CAD stuff is not just technology for technology’s sake; like in any business today, technology is a weapon. For instance, in 2003, Foster + Partners’ Swiss Re (aka the Gherkin) was a grand display of Sir Norman Foster’s trademark diagrid glass façade, adding to London’s and the world’s architectural vocabulary. The building was designed and modelled in MicroStation, with

Arups modelling the steel. Foster + Partners’ in-house team of geometry experts, the infamous ‘specialist modelling group’, wrote a program to produce take-offs from the model to automate the creation of pannelisation drawings. At the time, I knew of several firms which begged Bentley Systems to write a similar script for them, so they too could compete in the new vernacular with automated pannelisation take-offs, which they duly did. It’s now not unusual to find programmers in design practice and, to this day, Foster + Partners has the biggest in-house specialist team (but still less than 1% of total staff), producing tools for their designers, solutions for geometrical problems and developing inhouse applications.

Technology stacks

Having a Fab time

Today’s design IT directors live in a complex world. For most, budgets are tight, but they still have to develop their BIM technology stacks for multi-CAD environments, connecting and managing distributed teams and data, in different countries, with varying skill sets, complying to common standards and conforming to local standards. All this while working on projects and collaborating with other firms who might take a completely different approach to just about everything. Drilling down further, there are decisions to make on which platforms to use for design, document management, document distribution, common data environment (CDE), collaboration hub, security, visualisation, virtual reality (VR), augmented reality (AR), 3D printing and not to forget the workstation, mobile hardware and cloud services. With so many choices and so many moving parts, the day-to-day job involves the spinning of a lot of plates. With the increased update cycles, new software needs to be checked. All too often the technology stack can be undermined by just one or two components updating automatically and breaking essential links. Like painting the Forth Bridge, it takes so long to build a stack, that you need to start again when you have finished. It’s the pain that comes with building these systems which leads to the stickiness of solutions that ‘just work’ and is, in some way the attraction of SaaS services, which run off-site and take some of that trouble away. However, with change being inevitable, today’s generation of design IT directors are constantly scanning the market for technology to solve some of their current problems, improve workflows or prepare for any possible dynamic technology shift, such as 2D to BIM or desktop to cloud. Some of the larger firms might have a hand-picked R&D team, but most do not, and the task might befall to one individual. In times of significant change that responsibility can hang heavily. Process change can come at a productivity loss and an increase in risk in project delivery - the full buy in of the management team is essential. It’s another reason why the industry has tended to change slowly. But there are some changes, which simply cannot be ignored.

From talking to many AEC firms over the last year, it’s clear that a number of changes are coming together, which could have a fundamental impact on the way buildings are designed and fabricated. Whatever you want to call it, Digital fabrication, Design for Manufacture and Assembly (DfMA), Prefab, Modular or Precision Manufactured Housing, there is a general consensus that architectural design systems need to be able to better integrate with automated off-site construction machines. The bad news is that the BIM modellers which we have all standardised on, even though they produce 3D models, were never intended to produce accurate geometry to drive CNC (Computer Numerical Control) machines. They would also likely struggle to handle the size of models required for a level of detail that is needed to generate assem-

blies with detailed bill of materials (BOMs). All BIM modellers currently available were designed to automate the production of co-ordinated 2D drawing sets to be handed to builders to make. This isn’t the future. The UK already has a number of building factories being constructed, or up and working - Urban Splash, Legal & General and Berkeley Homes, to name but a few. Digital Fabrication is coming at a time when market dominating products like Revit are 20 years old and are only receiving minor updates each year. Revit still mainly runs on one CPU core, hardly makes use of GPU acceleration, and gets very unwieldy for large models often requiring them to be cut up. The net result is we are seeing a lot more activity in firms testing out alternative BIM products and even looking to software solutions which are popular in aerospace and automotive, such as Dassault Systèmes’ 3D Experience platform (better known previously as

Catia) and predominantly used by Frank Gehry and Zaha Hadid Architects (ZHA). While Catia is not used on every project at ZHA, it is used to send explicit 3D models to fabricators, bypassing 2D drawings for feedback on manufacturability during the design phase. It’s something that other firms are also buying into, such as SHoP Architects in New York, who has worked on a number of digital fabrication projects. Many other ‘signature’ architectural firms are looking to re-evaluate everything from conceptual design to fabrication. McNeel Rhino and Grasshopper seem to be the weapon of choice for firms that design freeform architecture and Rhino now works in SketchUp, AutoCAD, ArchiCAD, Unity, BricsCAD and Revit. This new development is called Rhino Inside (see page 31). Rhino Inside could potentially be seen as a liberating technology, as conceptual geometry created in Rhino with Grasshopper could be pulled out or injected into pretty much any of the main design and documentation tools. It would mean that Rhino becomes a common data e nv i r o n m e nt of sorts, but the geometry is essentially ‘dumb’, maintaining little of the ’I’ in BIM data. However, when it comes to ‘dumb geometry’, machine learning advances from companies like Bricsys have tools that could bring order out of the chaos. Its AEC modeller, BricsCAD BIM, offers a unique post-rationalisation capability, called ‘BIMify’, which can parse a dumb mesh model and intelligently work out what the BIM objects are, applying the correct IFC tags to elements it recognises, such as doors, walls floors, slabs etc. Dumb geometry need not stay dumb for very long. This could be game changing as you could pull models of cities out of Unity and set BIMify loose in BricsCAD! I’m calling this ‘Réchauffé BIM’ as it’s possible to heat up any geometry, back to BIM. Computational design or generative design has become a core design tool for many large firms, so if the base geometry stayed in Rhino, G-code could be easily generated from and it could also feed the model and drawing creation, a role for which BIM is slowly becoming relegated to. Products like ArchiCAD have built-in links to Grasshopper to drive BIM objects from scripts. This workflow is being evaluated by many architects wishing to automate the building of BIM models from September / October 2019

Financial drivers and locks With increasing costs for enterprise licences from Autodesk which, let’s face it, has the lion’s share of UK and US markets, the cost of software is also becoming a major driver. Firms are unable to leave subscription without losing access to all licences, but are very aware of how much they are paying and how little development their core BIM tool, Revit, has received. When one software vendor can dictate tough contract terms, AEC firms are made painfully aware every three years, of how little leverage they have. This is another reason for the current interest in evaluating what else is on the market. Autodesk is busy moving to the cloud and has decided the next generation of BIM modeller will reside there. Project Plasma (tinyurl.com/plasma-AEC) is the start of this core technology but has suffered delays and is probably years away. This is happening at the same time that digital fabrication is becoming a near-future consideration. This is probably not a good time to have your development ‘gap’. September / October 2019

Feature The industry is looking to liberate itself from proprietary file formats, which came with BIM modellers. In a federated working environment, poor interoperability leads to data wrangling, a potential to lose valuable information, and it impedes collaboration. Architectural practices have consciously expanded their toolsets to use best in class, so the search for industry standard CDEs goes on.

rises as processes are refined. Changes in materials, fabrication and automation will mean fundamental changes to design workflows and ultimately key deliverables. While in automation and aerospace 2D is still commonly used, the model definition is the key driver throughout its lifecycle. AEC has much to learn from lean manufacturing methodologies. We should all also be aware that there are giants of the tech world looking to disrupt this space. Ikea, Google and Amazon have their eyes focussed on designing, fabricating and delivering manufactured buildings. Even Elon Musk is trying to redefine construction, and looking to automate the creation of his Giga factories. Firms like Katerra have already started the process in the States (nxtbld.com/ videos/richard-harpham). It is time to re-evaluate our tools, our processes and deliverables to encompass a different future, where many buildings are designed for automated manufacture and assembly and an integrated approach to disciplines becomes essential. However, the barriers are not just techni-

This will extend to Mixed Reality headsets, Virtual Reality headsets, Android devices and maybe even games consoles. It’s not like Unity needs to reinvent the wheel here - all of these devices can already be reached through the core Unity platform - it’s just that they won’t be officially supported on Reflect yet. Multi-platform is a huge benefit of Unity and other game engines like Unreal Engine insofar as a model can be quickly pushed out to virtually any device, often at the click of a button. In the context of the AEC sector, it means a single real-time asset could be distributed anywhere and used for design visualisation, design review, project management, QA on site, and so on. “Some problems are more easily solved in Augmented Reality, and lend themselves to that, whereas some problems you don’t need to be on site and overlay anything,” says Adam Chernick, an Associate on SHoP’s Interactive Visualisation team. “It’s even more accessible and informative to put on a VR headset and immerse yourself in that space back in the office.” For a BIM model to be viewed in Reflect, it first needs to be prepped and optimised for real time 3D. This is an automatic, push button process, but it’s not instant. For a large model it can take minutes the first-time round, but after that the software only sends deltas, so any subsequent changes update in seconds. The Reflect Viewer can work online and offline, which is useful for those working on site. Reflect can be used out of the box and www.AECmag.com

Feature users do not need any knowledge of Unity itself. In this guise it’s really just a viewer albeit one that’s collaborative. It allows BIM models and filtered metadata to be viewed simultaneously by multiple participants on a variety of different devices, in different locations. This could be for design review, client presentations or simply to push BIM-rich data out on site. Having a live link can dramatically accelerate workflows. Firms can get feedback from clients or contractors, make changes in the BIM authoring tool, and then visualise them instantly on a tablet, or in VR. Previously, in order to get an updated BIM model into Unity, this could take hours or even days. Data flows very easily into Unity Reflect, but it is not bi-directional. The application is not currently designed to drive changes to the CAD or BIM model.

For this rail signal project, Unsigned Studio developed a Unity app that allows non-CAD users to drive detailed design. Signal designers and rail operators determine the optimal signal placement and the app then feeds the data directly into AutoCAD

Driving new workflows for AEC Unity has a long history with AEC firms who use it to help with specific workflow challenges not necessarily supported by off the shelf applications. At Unity Unite in Copenhagen last month, there were many great examples of firms exploiting the power of the real-time engine. Here are some of the highlights. SHoP Architects (shoparc.com) is no stranger to Unity – its R&D team has been developing for the game engine for some years. It is now one of the leading beta testers for Unity Reflect. Less time spent on data prep means the firm is now able to explore many more applications. AR Status Tracking is an iOS app which uses BIM data and Augmented Reality to visualise the construction status of projects. The app is being tested on the tallest skyscraper in Brooklyn to help non CAD users track construction progress of its exterior glazing panels. It works by pulling custom metadata from Revit and visualising it in Unity using different colours to indicate the status of each panel. SHoP first used the app in an office environment with a simple model of the building, visualised in AR using an iPad, but it is now looking to take it out on site as well to better connect design and

construction. It’s using object recognition to overlay BIM models on top of the construction site for QA and for giving site workers quick access to information, although there are still many challenges surrounding the accuracy of the overlay. SHoP is also exploring acoustics in buildings using VR. Typically, acoustic simulation occurs late on in the design process and the results are often presented in a spreadsheet which is hard to interpret. The practice has now brought this process more up front by making it visual and interactive. Taking material properties from the Revit model it can visualise how sound waves and wave fronts reflect off walls in an architectural space. And because it has a live link to Revit, teams can change the geometry and see the immediate impact on the acoustics. In this way, acoustic simulation isn’t just for verification, it can help drive design. We encourage you to check out SHoP Architects’ presentation at tinyurl.com/shop-unity Foster + Partners showed SandBOX I/O, a conceptual design tool built with Unity that can be used by pretty much anyone, including senior designers with little or no CAD experience. Users can build up models in 3D, comprising blocks, slabs and free-

form surfaces, and classify them by use, for retail, hotel, residential and so on. But SandBOX is more than just a mass modelling tool. The app can give real time feedback using built-in analysis functionality. In other words, it is performance-driven design. There are tools for analysing daylighting, financials and views. The results are presented by colour coding the blocks. So, for example, the parts of a building that will get a sea view (and hence could attract a premium) will be made blue and those that won’t will be made black. There are other types of analysis that can run on a floorplan, including pedestrian simulation or the walking distance between points. Traditionally, this conceptual phase required a multistage workflow, involving physical modelling blocks, and specialists in different areas of simulation. “A lot of these analyses typically took minutes, hours, days to run and we’ve spent a huge amount of effort, speeding up these analyses so they can run in real time or near real time,” says Francis Aish, head of Applied Research, Foster + Partners. “The speed of feedback to the users is absolutely critical, particularly if you’re with a senior designer with a client.” The software appears to be very easy to use and can be

Cockpit view from Laing O’Rourke’s VR crane simulator run on desktop, tablet or in VR, to suit different types of users. Lord Foster has even been seen trying it out with an HTC Vive! “Our goal is to enable senior designers to really engage and spend more time designing, and less time managing,” says Aish. Crucially, SandBOX I/O is not a closed application. It can share data seamlessly with other CAD / BIM tools, including Revit, Rhino (Grasshopper). This could be to feed-in site data to provide context for a new design, or to push out designs, complete with metadata, using the company’s in-house real time data exchange toolkit, Hermes. Laing O’Rourke is well known as a pioneer of Design for Manufacture and Assembly (DfMA) and has

state-of-the-art off-site manufacturing capabilities. When product sets including precast concrete building components are brought to site, the assembly process needs to as efficient as possible. Part of this is ensuring that the crane operations are derisked and optimised, especially the really tricky ones that need to be made blind. This can now be planned in advance, by sitting in a virtual cockpit in a VR crane simulator that was developed inhouse inside Unity. When working on the Google headquarters site in King’s Cross, for example, the VR crane simulator was also used to demonstrate to Network Rail that its modular systems could be moved safely next to the busy adjacent railway. Safety is a huge concern on construction sites, but tradi-

It would seem that Skanska wants to use VR to scare its workers into remembering what and what not to do on construction sites. Creative agency OutHere (outhere.se) developed a VR experience for Skanska using Unity. By all accounts the experience is quite full on, although Skanska drew the line at someone dying in VR. There is ‘maiming’, fire and falling concrete blocks. Some people have pulled out of the experience due to distress. The idea is that the stronger the emotion, the stronger the risk awareness when on an actual site. We didn’t get to see much of the actual experience – as Skanska doesn’t want its staff to know what to expect

- but the render quality was excellent, complete with driving rain and an angry, impatient foreman to disorient workers on the virtual site. Aurecon (aurecongroup.com) is a global multi-disciplinary, engineering consultancy that now has its own independent 3D visualisation and creative technology studio. Unsigned Studio (unsignedstudio.com) is doing some incredible stuff with Unity, making custom applications to visualise the entire engineering project lifecycle, from the proposal stage, through concept and detailed design, and into construction and asset management. To aid development it has created siteLab, a framework on which it can build a variety of different apps without

having to reinvent the wheel for every project. It includes editor tools and workflow, integrated desktop and VR and is mobile ready. In his presentation, Michael Gardiner, Studio Leader (Brisbane), gave so many excellent project examples that we’ll cover them in more detail in the next edition. There’s some great use of point clouds and applications for end user testing in VR to ensure the design is actually fit for purpose. Sitowise Design (sitowise. com), a Finnish-owned, construction focused planning and consulting agency, has also built a platform on top of Unity, but Aura is a virtual environment that can be utilised for the creation of digital twins. It can combine people, traffic, buildings, weather and lighting with

precise IoT sensor data. The agency is involved in many different projects including one for a Finnish university that is helping to ensure that a plant room runs optimally. Using IoT technology, it monitors things like air flow and pressure and uses mathematical algorithms to identify potential problems across 40 individual HVAC machine units. Sitowise Design is also using Aura for a port project, where the harbour has been modelled and IoT technology is used to track crane and ship movements with a view to optimising loading / unloading operations. PREspective (prespective.eu) is a Unity-based tool from Unit040 dedicated to the creation of Digital Twins. The firm has a strategic partnership with Unity. In fact, Unity

actually sells the software. PREspective is mainly used to simulate complex systems, ranging from machines to entire production facilities. However, the software has also been deployed on some infrastructure projects. The thing that stands out with PREspective is that it can run the actual control software which will drive the asset during operation. It means everything can be properly tested prior to deployment. For real-time simulation of infrastructure projects, firms can virtually test toll bridges and tunnels before they are built, complete with intelligent cars, boats, pedestrians and cyclists. The simulation can also be used to collect IoT data for predictive maintenance or for training.

Feature Grasshopper. Unsigned Studio has developed siteLab, a framework on which the 3D visualisation and creative technology studio has built a variety of impressive AEC-focused applications for desktop, mobile and VR. There are many more examples in the box out on page 22. Impressively, much of the development work for these projects has been accomplished without any real help from Unity, at least from an AEC industry perspective. More importantly, any AEC firm working with BIM models has had to solve the huge workflow challenge of bringing geometry and (sometimes) metadata into the Unity engine. And then doing it again and again for every new design iteration. Speaking at Unite, Graham Brierley, digital engineering lead for the European Hub at Laing O’Rourke, said the Unity developers in his team spend 60% of their time optimising models for Unity, meaning less time spent on app development. SHoP Architects is one of the leading beta testers for Unity Reflect. In the past,

Unity Reflect puts BIM data at the fingertips of many different stakeholders. Currently there is a Reflect Viewer app for Windows and iOS. More apps will come

p22_23_24_25_26_28_AEC_SEPTOCT19_Unity3.indd 26

time spent on data prep was a major barrier to the wider use of the Unity engine throughout the practice. Before Unity Reflect, the traditional workflow from Revit required the team to decouple the geometry from the metadata, via FBX and Excel, and then recouple it in Unity. Adam Chernick explains the difficulty of this process, “It actually took teams days or weeks in order to optimise and convert these models into real time ready assets and this really didn’t align with the speed of iteration that we needed in our office. And, of course, the consequence was that not a lot of our projects made it into real time engines.” “It took so long to get stuff in that, by the time the tool was used, it’s like ‘that was fun, but… the design has already moved ahead,’” adds SHoP Architect’s Christopher Morse. By addressing interoperability with Unity Reflect, this should open up huge opportunities for AEC firms - less time spent optimising data and more time developing practical applications, as well

as making the UI and UX more effective. Unity’s helping hand won’t just be limited to data optimisation. The company also plans to develop toolkits and templates on which users can build apps, such as the Immersive Collaboration Toolkit, which provides the foundation for developing collaborative design review experiences in VR. There are also plans for new apps.

Unity and viz The Unity engine offers very high-quality real-time rendering. You only have to see what companies like Lexus are doing with digital studios to appreciate how good the results can be. Render quality will get even better next year when physically-based real time ray tracing is added to the engine, powered by Nvidia RTX technology. Despite these capabilities, high fidelity design visualisation is not currently a focus for Unity Reflect. That’s not to say it won’t be in the future. For example, Unity is already working on bringing entourage (RPC content) in from Revit,

including trees and vegetation. It would also make perfect sense for a third-party developer to build an architect friendly viz tool on top of Reflect. Only having to manage a single real-time asset that can serve many different workflows in architecture, engineering, construction and viz is an exciting proposition. From a design viz perspective, Unity is some way behind Epic Games, the developer of Unreal Engine. Epic Games owns TwinMotion, an easy-to-use, real-time viz tool built on top of Unreal Engine. Chaos Group also offers an optimised workflow into Unreal Engine from V-Ray, the number one render engine for arch viz. Of course, there plenty of other ways to bring viz assets into Unity, not least via FBX. Cinema4D also has a new Unity plug-in, which will have a live link capability soon.

Conclusion When game engines first came on to the AEC scene, the emphasis was on their ability to deliver high-fidelity, real-time experiences at high frame rates. With Unity, the rendering quality and performance can be great, but the company’s focus appears to be on building practical workflows around information-rich BIM models. Unity may have been used in the AEC sector for years, but it’s still relatively unknown among the wider community. Now with Unity Reflect, which does not require specialist programming skills to use out of the box, along with the company’s close relationship with Autodesk, this will almost certainly change. From what we have heard from the beta testers, Unity Reflect does an excellent job of solving the interoperability challenges that exist between Revit and the Unity engine. In a single click, it can 28

p22_23_24_25_26_28_AEC_SEPTOCT19_Unity3.indd 28

do all the complex work of preparing, federating, and transferring BIM data. With planned support for Rhino, SketchUp and Navisworks, Unity has many bases covered, particularly as Navisworks can already read in data from multiple sources. Extending this support to other BIM tools would really help turn Reflect into powerful hub for AEC data - a hub that can push out optimised geometry and metadata easily to VR, MR and mobile devices. But it needs to be done in a managed way, so plumbing Unity Reflect into Autodesk BIM 360 would make perfect sense. Of course, the real power of Unity is that it is open and firms can build applications on top to help support specific workflows in the AEC sector - from conceptual design and construction simulation to quality assurance and digital twins. There’s a huge opportunity here for third party developers in particular and wouldn’t it be interesting if Autodesk became one of them?

For in-house developments we expect more AEC firms to experiment with the engine now the interoperability barriers have been broken down. Unity is not the preserve of the mega practices with large R&D teams. SHoP Architects, for example, has less than 200 employees but is already doing some incredible projects with Unity Reflect. Even though your average architect or engineer won’t possess the necessary C# programming skills, there’s a huge community of game developers out there that can bring fresh ideas to AEC firms of all sizes. Some of the more progressive AEC firms are already tapping into this talent. But the biggest prize for Unity in the AEC industry is with off the shelf software. Unity Reflect will almost certainly grow in capability (after all it hasn’t even been released yet). Unity also has plans to produce more apps of its own. And with the company now investing heavily in AEC, we’re excited to see where things go. ■ unity.com/aec/reflect

Global Cities Innovate with 3D Modeling Leaders use realistic cityscapes to make decisions, collaborate, and improve quality of life

hen smart cities need to make planning, infrastructure, and services decisions, they increasingly turn to virtual cityscapes to model scenarios and understand impacts. London, Helsinki, Boston, and Singapore are among those leading the way. 3D city models provide realistic renderings of existing buildings (inside and out), transportation infrastructure, and green space as well as proposed projects. With 3D models, it’s easier to see how a new building, solar panel installation, or bridge would impact an area. Once a plan is proposed and integrated into the model, it becomes an effective tool for communication with partners and the public. Beyond planning, these models are invaluable for situational awareness and emergency response. Geographic information system (GIS) technology has been the primary means for developing these realistic models. Unlike physical models or twodimensional drawings, governments can easily modify 3D cityscapes to reflect new buildings, new materials, and even changing landscapes. In Boston, the Boston Planning & Development Agency uses its 3D model for flood modeling, lineof sight evaluations, and shadow studies that guide development near the historic Boston Common. With a law in Massachusetts restricting the amount of time any building can cast shadows on Boston Common, the city needs detailed analytics on how proposed development would affect the nation’s oldest park. Replacing its wooden physical model with a 3D digital model, gave planners access to details they could not visualize before. They can clearly see how new zoning and development could lead to increased shadows on the park at various times of the year when sun angle and daylight hours vary. City leaders quickly realized how having upto-date, detailed images of Boston’s buildings and assets significantly benefited collaboration among stakeholders including city staff and developers. It also put data at the center of critical decision-making and negotiations. Now they want to extend the benefits to others. “We want to make the smart 3D model user friendly and widely available to whomever for whatever,” said Corey Zehngebot, senior architect and urban designer at BPDA. “The sky’s the limit in terms of what we might be able to use it for in the future.”

improve the lives of our citizens,” said London’s Chief Digital Officer, Theo Blackwell. Helsinki’s Chief Digital Officer, Mikko Rusama, added, “Helsinki’s vision is to be the most functional city in the world that makes the best use of digitalization.” As the leaders of these two tech-savvy cities are keenly aware, the visual nature of maps simplifies communication about challenges, existing situations, and possibilities. 3D models give smart cities an effective way to collaborate internally, with the public, and with other governments. CREATING A DIGITAL TWIN Moving farther east, the global powerhouse city of Singapore is also making significant investments in 3D city models for broad use inhouse and with citizens. Singapore has invested millions of dollars in its 3D model that will be used by government agencies and the greater public. The Prime Minister’s Office, National Research Foundation, Singapore Land Authority, and Government Technology Agency of Singapore are all backing the project. The 3D model will provide an effective way to test ideas, plan, and address local challenges associated with growth

and other pressing issues. The information in Singapore’s model goes well beyond structural data. Singapore will include vast amounts of terrain, demographic, and climate data combined with real-time sensor data. Visualizing building, the natural environment, and the movement of people will help the government determine where to invest in new infrastructure and effectively deliver services. It will benefit everything from planning to disaster response. Though these cities are investing millions in their efforts, creating 3D models is within reach for many cities now that the cost of capturing imagery is shrinking with the widespread availability of drones and other forms of rapid imagery capture inside and outside of buildings. The 3D city models combined with comprehensive strategies on how to use them—as we see with London, Helsinki, Boston, and Singapore—will help leaders move smart growth plans forward and enhance quality of life for citizens.

COLLABORATION BETWEEN CITIES The trend toward 3D modeling is gaining traction across the globe. In February, the cities of London and Helsinki announced they are working together in a ‘City to City Digital Declaration,’ sharing best practices on 3D city modeling among other tech-related initiatives. “This Digital Declaration sets out a formal framework for co-operation between Helsinki and London to develop our respective in-house expertise and links with the tech sector to use city data to

Rhino Inside Rhino 3D with Grasshopper occupies a special place in the AEC industry. Now, to complete global domination, McNeel will soon make the software able to work in pretty much any Windows application, such as Unity, AutoCAD or even Revit by Martyn Day

hile most firms make a big song and dance about their releases, McNeel chooses its own path. Over the years it has developed a large and loyal community, covering many vertical markets, from jewellery design to ship building, together with an ever-expanding ecosystem of add-on applications. The company originally released the Rhinoceros 3D modeller in 1994. And, together with the Grasshopper 3D scripting visual tools, has become endemic in the AEC industry for conceptual and geometric definition.

Xinaps Verifi3D

BIM offers many benefits, not least its ability to check a design’s overall quality, to identify spatial, functional and data errors. Xinaps has a new customisable, cloudbased checker for Virtual Design and Construction professionals

by Martyn Day

IM models get big, fast. When it comes to checking co-ordinated models, it’s best not to do them in the authoring tool, but outside in something faster. In fact, the loading and manipulating of large or co-ordinated BIM models is so troublesome that there is a whole industry based around developing tools for the optimisation, display and interrogation of big AEC datasets. Verifi3D is a completely fresh and unique take on this growing Common Data Environment (CDE) sector of the market, enabling cloud-based model visualisation, geometry and data validation, clash checking, analysis, reporting and more to aid ISO19650 compliance. The main competitors in the space are Navisworks, which is old and end of life, and Solibri which, while being the de facto standard and a powerful pro level tool, is expensive and complex to learn. There’s also Autodesk’s BIM 360 Glue, which requires data to be centrally located and currently lacks a lot of the capabilities found in desktop Navisworks. Xinaps’ Verifi3D is a fast, cloud-based, feature rich, very easy to use, alternative validation tool for all BIM workflows. First off Verifi3D is a service, and sub32

scriptions are based monthly or annually. As it’s cloud-based, the feature set is expanding weekly and in fact I have had to look at the software three times while reviewing it, as additional functionality has been appearing within the last month. The Verifi3D viewer runs in a browser, where files can be dragged and dropped, or located via a project browser. Alternatively, Verifi3D accounts can be connected to BIM 360, allowing seamless access to the latest project models stored on Autodesk’s backbone. Other integrations will come soon.

unich-based Nemetschek is a very unusual software company. All of the other software developers in the industry have one BIM product. Nemetschek owns three: AllPlan, ArchiCAD and Vectorworks. With sales in over 85 countries and a very strong presence in Europe, the company seems comfortable with selling what, on the face of it, appear to be competing platforms. Allplan and ArchiCAD have their origins in Europe. Vectorworks was born in the mid 1980s and started off life as MiniCad for the Apple Macintosh. Around the year 2000, it transitioned to the Vectorworks brand when it was acquired by Nemetschek. Each of Nemetschek’s BIM brands are run as separate concerns and have different approaches, methodologies and underlying technologies to deliver www.AECmag.com

on the process of BIM. Despite its apparent age, Vectorworks has been undergoing a radical re-architecting and a fleshing out of its BIM capabilities. Until recently, it was only one of two platforms for construction that used a solid modelling kernel to underpin its geometry. Both Bentley Systems and Vectorworks utilise the Parasolid kernel from Siemens. There’s also a new kid on the block called BricsCAD, which uses the ACIS kernel. It turns out that having a powerful geometry engine, usually found in manufacturing CAD systems, may well be a better match as the industry moves to embrace digital fabrication. In this release, Vectorworks has actively exposed some of the more powerful solid modelling methodologies of Parasolid, to make accurate manufacturable components, but more on that later. One other unique feature in the

Vectorworks offering is the way that the technology comes in a variety of flavours. There are seven options to choose from. Landmark is a very well-regarded and comprehensive landscaping variant and Spotlight has single-handedly developed a leading role in the world of stage and lighting design. The others are Fundamentals, Architect, Braceworks, Vision and Designer. The feature updates range across these variants, some being common, some being unique to the industries that are focused upon.

on the fly, optimising the load on the graphics card. This is used when zooming, panning and using ‘fly over’ in the model. Files open faster and 3D frame rates are improved.

Live data visualisation This new feature enables components within the building to be assigned colour attributes, depending on their object parameters. It could be used to check models visually during the design process. Live data visualisation is like a lightweight Solibri capability, so you could instantly see which doors lacked fire protection or what are supporting structures vs partition walls. It could also be used for massing analyses with various residential units, or in the Landscape variant, to see which plants had the highest solar requirements, pricing or water needs. It’s completely user configurable and it’s possible to have colours automatically associated to groups of components, such as fire door rating times, for instant identification within your model. Multiple visualisation sets can be created through a simple interface and stored/reapplied throughout the design process. These can also be shared between files and projects.

History-based modelling This is a feature I never expected to see in an architectural design tool. Historybased modelling is a common modelling paradigm in manufacturing CAD. Essentially, to achieve the desired geometry, a range of operations are applied to define the shape of the building component, such as rounded edges, fillets, shells and chamfers. The history tree is the recipe of sequential commands used to create the component and they can be edited or removed from the tree, impacting the resultant component when ‘rebuilt’. There are navigation tools to run through the history and locate the function that needs changing, and after all edits made the software re-builds the component to reflect the changes. This approach to modelling allows for an iterative design process and means components don’t necessarily have to be deleted www.AECmag.com

BIM standards. It’s possible to gather, filter and organise select objects based on their class, symbol definitions, and origin (Vectorworks or 3rd party). With each object, you can examine the attached data by its mapping and look at the data fields and sheets, at all the levels of detail (LOD). Here you can also map model object information to IFC standards through custom fields and formulas. Speaking of IFCs, there is the new ability to reference IFC files so they don’t need to be reimported during the design process if they get changed. Data tags have also been enhanced and expanded.

Sections Creating section views has been enhanced in this version. Improvements range from being able to control the level of detail for building elements (e.g. windows, doors), to the ability to adjust cut plane settings on individual objects. There’s also the option to show colour fills and planar objects in hidden line viewports.

Doors and windows 2020 has had many small and large improvements to window components - to improve speed and control of placement, LOD detail, as well as to enable rapid modelling and editing. Hipsters everywhere will be glad to know that this release features ‘barn door’ style doors, and there are lots of different types to choose from! And if none meet your requirements, of course they are completely editable. Windows have similar control and LOD updates.

Case study

Backing the future Digital technologies were key to communicating the design and overturning planning objections for a contemporary extension to a mid-nineteenth century Dublin house.

rish architect practice Cummins + Voortman has revitalised a mid-nineteenth century Dublin house with the addition of a distinctive extension. Following a complex design, planning and construction process, the listed property now boasts a contemporary copper and glass kitchen and living space, which replaces a twentieth century glass conservatory. The new structure is formed of two intersecting cubes. One replaces the previous kitchen to make use of the existing services and the other accommodates a new dining and living area. The existing stone steps have been retained with a landing area at the top, providing access to and from the garden. The extension is a striking addition to the historic building. However, its sensitively designed, transparent form – created using modern materials and construction techniques – allows it to sit lightly next to the original brick structure.

Planning challenges The original design was completed by architect Caitriona Noonan, who modelled the proposed extension in ArchiCAD following a number of workshops with the client. But the unconventional design meant gaining planning permission proved a challenge. Concerned that the extension would obstruct the view to the garden from the reception room, the planners eventually granted permission, but on the condition that the extension be halved in size, so it did not span the full width of the house. Undeterred and convinced that the project should continue as designed, the client asked Cummins + Voortman to assist with an appeal. Cummins + Voortman carried out a visual impact analysis, requiring more detailed texture mapping and comprehensive modelling in ArchiCAD, in conjunction to the written report compiled by Catriona Noonan. 40

September / October 2019

p40_41_AEC_SEPTOCT19_ArchiCAD.indd 40

Clarity though the cloud Cummins + Voortman began with an analysis of the existing ArchiCAD model. The historic house is a listed property with uneven original walls. The existing survey information didn’t provide enough detail, so Cummins + Voortman commissioned a detailed point cloud survey. With the survey complete, the architects could model the existing property and the extension with total accuracy. The survey data was so large (13GB), it had to be divided into 10 parts to be imported into the ArchiCAD model at full quality scan resolution. Cummins + Voortman then completely remodelled the design in ArchiCAD with the point cloud data included. Bernard Voortman, director of Cummins + Voortman, explained: “Once the point cloud survey was complete we were confident we had all the information we needed. It was so useful to be able to accurately model the position of walls, architraves, skirtings and ceilings for example – to assist with the decision making for a complex listed building. “It was also very helpful in getting the levels right, to make sure the new extension was properly aligned with the old building. In this instance, using the point cloud was the only realistic way to model the old non-linear walls; if we’d used a conventional point laser handheld distance meter it would have taken far too long.” The point cloud survey also helped minimise the disruption to the client. “There is less measuring and doublechecking on-site,” said Voortman. “There’s no need to go back to the property multiple times to take photographs. Once you have a point cloud survey with adequate colour values you can work from the model with 100% confidence that it’s right.”

Winning the appeal With the new ArchiCAD model complete, Cummins + Voortman produced a walk-

through video, a sun study and a full suite of photographs and images showing the existing property with the conservatory and the proposed extension. As a result, at the appeal, the condition for the half-size extension was overturned and the client was able to continue with the original designs. “With the help of ArchiCAD’s realistic rendering the planners were able to visualise the design, which was incredibly useful in the planning process,” said Voortman. “It’s all about achieving optimal communication of the design.”

Precision build The contemporary extension required a high level of precision during the construction phase. The extension needed to sit tightly between the existing building and the original deformed stone boundary wall and under a stone window sill at roof level. It was therefore essential that the design was fully detailed beforehand, with all critical junctions solved in terms of water proofing, airtightness and thermal performance. “We appointed a master builder as the main contractor for this project,” said Voortman. “We needed someone who was highly competent to manage the project and who was also used to working with digital technologies.” The extension was constructed using a steel and timber frame with large areas of structural glazing. The steel and glass were pre-fabricated offsite and then assembled onsite. This required verified model consistency to ensure all elements fitted together. There was no room for error.

Careful collaboration Throughout the build process the architect, main contractor, structural engineer, steel subcontractor and glazing manufacturer worked closely together. “By using the point cloud survey, we were able to manufacture the steels directwww.AECmag.com

03/10/2019 17:06

ly from the data taken from the ArchiCAD model,” said Voortman. “Although the structural engineer was also using ArchiCAD, they preferred to exchange information using IFC. Information was then sent to the steel subcontractor via IFC and conventional drawings.” The specialist glazier required minimum tolerances which demanded a high level of certainty at steel installation, glazing design and assembly. Once the steel was in place, the glazier carried out its own point cloud survey and found there was only five millimetres difference between the installed steel and the model. The overall construction process was flawless and all elements fitted perfectly once they arrived onsite. www.AECmag.com

p40_41_AEC_SEPTOCT19_ArchiCAD.indd 41

Enhanced communication Throughout the project, Cummins + Voortman used the virtual reality presentation app BIMx extensively with the client, contractor and subcontractors. The contractor also used BIMx to improve collaboration and to share information with the whole team. “BIMx gives us a tremendous amount of confidence in our design and it really helps to coordinate and communicate with clients,” said Voortman. “During the construction phase, we used BIMx and the Google cardboard viewer with our client onsite, which allowed him to stand in the building and see exactly what the extension would look like when it was completed. He

absolutely loved that.” Cummins + Voortman also used the completed ArchiCAD model to help the client assess kitchen designs and choose materials. “The high-quality renders and the BIMx hypermodel helped with the decisionmaking process and gave our client full confidence in the proposed design,” said Voortman. “BIM is better experienced than explained. Its true value becomes clear when you deliver a project. For this project, the overall satisfaction from the client was 100% and we are confident in the knowledge that we have delivered a beautiful, high quality extension.” ■ graphisoft.com

Build:London 2019 Epic Games’ Build:London event has become an essential diary date for the AEC fraternity. There’s a great balance between showing real-world applications and giving insight into what’s coming next in Unreal Engine by Martyn Day

here was a time when Virtual Reality was all hype; now it’s a reality in most of the major AEC firms. While VR is still used mainly as a customer-facing technology, there are a number of companies that are deploying it as a design tool, from concept through to validation. Unreal Engine by Epic Games has been one of the driving forces behind the rise of VR in the AEC sector. This is mainly because the 3D engine can be used to create visually impressive, custom VR experiences, but it is also down to AEC-focused applications that are built on the 3D engine, such as TwinMotion, which Epic Games acquired earlier this year. To support its growing community,

Epic Games now hosts an annual London event focused specifically on the AEC market. Build:London showcases the breadth and depth of real-world applications from users of Unreal Engine as well as giving the community an opportunity to see new developments in the software.

The conference The first presentation was an onstage interview with CG artist Alex Roman, creator of “The Third and Seventh”. Roman manages to create amazing, gobsmacking realism and cinematic beauty in his architectural CG visualisations and films, using V-Ray and Unreal. This was an impossibly high bar to match for rendering quality. Gabriele Sorrento, the CEO of Mindesk then gave a presentation of

Mindesk Bridge, a VR design tool for McNeel Rhino and Solidworks. While the software can be used to model geometry in VR, at the moment the most common way to use it is as a design review tool. Assemblies are imported and the application allows control over transparency of objects, ‘explosion’ of assemblies and even kinematic movement, all in VR. Sorrento was joined by Helmut Kinzler and Aleksandra Mnich from Zaha Hadid Architects to show how they used Mindesk with Rhino to explore a project they had recently worked on, the L-Acoustics ‘Loop Sound lounge’ chair. Mnich gave a live demonstration of geometry creation, creating surfaces to complete an enclosure.

extremely heavy on data. This will be coming soon, as Unreal continues to focus on being able to integrate common AEC formats. We were also treated to a sneak-peek at early development work on a core geometry modelling engine that’s being created inside Unreal Engine. It looked to be powerful and intuitive (push/pull driven) and capable of making complex forms. This should be an interesting direction for the company. The next release will also have a real physical sky and while Unreal is all about real-time, the release will be able to render super high resolution 20k in a non-real-time mode.

Conclusion The running themes and messages from the talks were that Unreal Engine can handle huge models of detailed landscape. It eats complex geometry without any impact on the frame rate and speed of experience. Frankly it seems like CG alchemy! It’s clear that there is a trend to deploy VR in conceptual design, model checking, data analysis, training and experimentation. By moving VR from a backend to a front-end tool, early adopters are finding useful insight into their designs. Virtual Reality is in itself a design application not just an experience. However, we have yet to be convinced that accurate surface modelling in VR with current input and manipulation wands can compete with a mouse or pen-based desktop system, but it’s not stopping people from trying. What seems to work the best is if the models are blocks, like Minecraft, so perhaps massing will become increasingly popular. ■ unrealengine.com

Software

Enscape 2.6 Real-time rendering software developer Enscape has just completed a major overhaul of its flagship product and laid some groundwork for soon-to-be-enabled, ray tracing enhancements with Nvidia RTX by Martyn Day

ut of all the various software technologies that are deployed in the AEC market, visualisation undoubtedly moves at the quickest pace. It is driven by advances in the games industry, graphics hardware, and a plethora of VR and AR developments. Today with increased competition, the net result is regular big improvements to provide amazing ondemand high-fidelity images at incredible speeds, together with VR on demand for both making design decisions and

selling projects to customers. When it first launched Enscape redefined ease of use with a simple ‘one click’ approach to generating photorealistic real time environments. It is one of the most popular viz-focused add-ons for Revit and SketchUp. More recently, it has added support for Rhinoceros and ArchiCAD. Typically, architects work on designs with their BIM tool of choice and, with one click, Enscape delivers high-quality realtime environments to explore for instant design feedback. The software can also cre-

ate video walkthroughs and VR experiences in a single click. These can also be sent to clients as a self-extracting executable, without the need for an Enscape licence, or turned into a WebGL-based website. With an aggressive upgrade cycle, this is the second release of the year. Its capabilities have continuously improved and expanded. The latest release does not disappoint.

Enhanced lighting and reflections Enscape is different to most other real time renderers in that is uses elements of ray tracing. The results approach photorealism but are not as accurate as those from a dedicated ray trace renderer like V-Ray. For the new release it has overhauled and enhanced the lighting and reflection algorithms. This delivers speed improvements and also improves the product’s reflection fidelity, meaning geometry which is offscreen or obscured by other objects can reflect in high detail, within the scene. Texture maps are now more accurately displayed, as well as cutout materials, which now appear reflected in mirrors and other reflective surfaces, together with any corresponding shadow. Light sources are also better represented in reflections. Interior lighting has been www.AECmag.com

tweaked to produce more natural results, with less light leakage and more pronounced indirect shadows.

New ArchiCAD Material Editor Enscape added support for ArchiCAD in June 2018 (2.3). This release brings a major improvement for users of the BIM tool, now supporting the Enscape Material editor, enabling access to, and editing of, the full spectrum of material parameters. New controls for bump maps, which were previously not supported in the native ArchiCAD Surface Editor and a roughness editing tools can help finish off a scene by making it looked lived in.

Asset Library Expansion Scenes need more than just high-quality materials and lighting to give a feeling of reality. It’s important to be able to add assets quickly and easily to dress the scene. With Epic Games acquiring TwinMotion earlier this year, competition is heating up and Enscape has responded by dramatically adding to its asset library. With this release come over 300 new models, including people, tropical plants, home accessories, bathroom assets, street signs, vehicles, food, vegetation, furniture and more. Additionally, Revit users now have www.AECmag.com

p46_47_AEC_SEPTOCT19_Enscape.indd 47

expanded placement options: on a surface, on an active work plane or linked to an existing Revit family. There are standalone files for each of the categories, so users can browse the asset groups before placing them in a project.

Enhanced Settings In previous versions of Enscape, the scene settings were stored separately to the BIM model. This meant that when moving data from machine to machine, the Enscape Settings for the model did not match the original intent. It’s now possible to save the settings within the CAD file, so you can share your model with other Enscape users, who can repeat the same render and get the same results. It’s a small feature but very useful for teams. It’s also worth noting here that in settings there is now support for numerical input in addition to sliders.

Nvidia RTX Nvidia’s new GPU-accelerated physicallybased RTX rendering technology looks set to revolutionise high resolution, real-time photorealism. Those of you that attended NXT BLD this June will have seen a number of talks demonstrating the potential benefits of RTX-assisted rendering on desktop and mobile workstations.

We were fortunate to have Enscape’s cofounder Moritz Luck, showing an early ‘work in progress’ version of 2.6 (nxtbld. com/videos/moritz-luck) on an RTX-enabled laptop, where Enscape smoothly rendered a very large and reflective building model in real-time, while the camera flew about the site. It was interesting to see the quality improvements delivered by RTX, specifically around reflection. However, before you get too excited, at the time of going to press, the RTX acceleration in 2.6 was disabled, due to some stability issues being sorted out by Nvidia. We have been told this will be enabled in an update soon. There are already some enhancements to the existing ray tracing engine in 2.6, but RTX will take ray tracing in Enscape to new levels of quality through physically accurate reflections and diffuse, indirect lighting. There is an array of other smaller features for this 2.6 release. It’s possible to reduce the memory usage by down-sampling some of the larger textures, there have been improvements to all sun shadows. Oculus Rift S controllers are now supported and are visible during VR sessions. Enscape 2.6 is now available for download and comes with support for Revit 2020. ■ enscape3d.com

Total Chaos and beyond Chaos Group’s V-Ray renderer is the architectural visualisation industry’s market leader. Now that it also owns Corona Renderer, the company is a global dominant force. Martyn Day reports fom the company’s huge user event in Bulgaria.

t doesn’t really matter what core modelling tool you use, Chaos Group has a plug-in product product for you. Whatever your poison — Rhino, Revit, Unreal, Blender, Maya, Max, Modo, even Form-Z — there is a flavour of the company’s flagship V-Ray physics-based renderer to plug-in and generate some amazing photorealistic images and films. With a passionate community that laps up every update and every millisecond saved per render, Chaos Group has accidentally morphed its annual local

user event into a huge international conference with lots of workshops. Called, of course, ‘Total Chaos’, the event is held in Bulgaria’s capital city, Sophia just down the road from the company’s offices. This year it featured over 900 attendees, with over 50 sessions, featuring 77 speakers over two days. As many rooms and workshops run simultaneously, sometimes the event can live up to its name, especially if you don’t plan your agenda in advance. After a day of masterclasses, the two day conference kicks off with a keynote from Peter Mitev Co-founder and CEO.

This year the company had refreshed its product line with its next generation renderer, V-Ray Next, delivered for V-Ray and Corona for Cinema 4D users. It also entered the real-time world of VR with V-Ray for Unreal, expanded its materials development with its VR Scans business and launched Chaos Cloud. Paul Debevec from Google Daydream gave a fascinating talk on his development work on HDR 360 panoramas and lightfields which has been used in everything from films such as Gravity to Smithsonian VR installations.

Co-founder and CTO, Vlado Koylazov gave a technology deep dive into where V-Ray is going next and the technology under the hood, from. This year it was about the development of super-fast V-Ray Next which has been delivered throughout this year and is now receiving updates and refreshes.

Sessions Attendees to the event come from all sorts of backgrounds, CG artists, architects, engineers, product designers and software developers. To reflect this, the sessions are broken down into three simultaneous streams - Art, Craft and Code. Here you can listen to CG artists, skilled VR environment designers, cloud computer specialists, FX specialists, architects, scientists and software programmers. It’s possible to go as deep into the technology as you want, or just watch an incredible artist talk about how they created their images. Chaos Group has made 31 of the talks, which could pass copyright clearance, publicly available on YouTube at tinyurl.com/TotalChaos19 With so many speakers, three simultaneous tracks, an exhibition, coffee breaks, lunch breaks, and evening social gatherings, Total Chaos is a completely immersive experience and you are guaranteed to come back with industry friends. Being held in Sophia, the Chaos

Group development teams are all on hand to help and advise and rarely for software company, they love to show software that is still in development. We highly recommend a trip and we guarantee you will love the city and the people.

Latest news At Siggraph this summer, Chaos Group demonstrated some new features to its Project Lavina, which can ray trace massive V-Ray 3D scenes using GPUs without workarounds or any complex setup.

To prove this point, the company showed the fully interactive manipulation and subsequent rendering of a 1-billion polygon KitBash3D city. V-Ray Next for Rhino has just received its update 1, which brings faster CPU renders, updated materials workflow and support for a more advanced computational geometry engine. It also supports Grasshopper animation and has better support for V-Ray materials . Highlights of the update can be seen here youtu.be/mxTv6cUZIww ■ chaosgroup.com/total-chaos

HP ZBook 14u G6 Portability doesn’t have to come at the expense of performance as Greg Corke discovers in this impressive 14” CADfocused mobile workstation from HP It wasn’t that long ago that mobile workstation manufacturers only had two or three machines in their range. But times have changed. And now with eight models in its ZBook G6 family, between them offering power, portability and 2-in-1 capabilities, HP has taken things to extremes. Weighing in at 1.48kg and measuring 326 x 234 x 17.9mm, the HP ZBook 14u G6 is the smallest and lightest in the family. A 14-inch mobile workstation used to mean a big trade-off in performance, but with new power efficient CPUs and GPUs this is becoming less of a concern. You wouldn’t want to rely on the HP ZBook 14u G6 for real-time visualisation or ray trace rendering, but for 3D CAD and BIM it can stand shoulder to shoulder with machines of much higher specs.

core Intel Xeon E-2276M (2.80GHz, 4.70GHz Turbo). Of course, performance falls off dramatically in multi-threaded workflows, such as ray trace rendering. With fewer cores running at a lower frequency, we found render times in our Chaos Group V-Ray and Luxion KeyShot tests to be significantly slower than a mainstream six or eight core mobile CPU. However, rather than dropping all the way down to the base clock speed of 1.8GHz, the HP ZBook 14u G6

Graphics tuned for CAD

Power in small packages The HP ZBook 14u G6 is built around a power efficient quad core version of the 8th Gen Intel Core processor. With a 15W Thermal Design Power (TDP) - the average power a processor dissipates when operating at base frequency with all cores active – these “Whiskey Lake” CPUs draw significantly less power than the 45W six and eight core CPUs used in mainstream mobile workstations like the HP ZBook 15. Low power does mean a performance trade-off, but only really in multithreaded workflows. The Intel Core i5 8265U (1.6GHz, 3.9GHz Turbo), Intel Core i7 8565U (1.8GHz, 4.6GHz Turbo), Intel Core i5 8365U (1.6GHz, 4.1GHz Turbo) and Intel Core i7 8665U (1.8GHz, 4.8GHz Turbo) all have low base frequencies when running all four cores, but the GHz can be boosted significantly when only using a single core. And single threaded performance is where is counts for CAD. When exporting an IGES model from the 3D CAD tool Solidworks 2019, for example, our test machine’s Intel Core i7 8665U went up to 4.2GHz. And the 85 secs it took to complete the test is on par with most other mobile workstations, including the Lenovo ThinkPad P53 we reviewed in June, which had a six www.AECmag.com

maintained a solid 2.4GHz with very little fan noise - even when rendering for well over an hour. HP appears to have done an excellent job on thermal management. The HP ZBook 14u G6 supports up to 32GB of DDR4-2400 non-ECC SDRAM, spread across two SODIMMs. This should be plenty for most mainstream CAD workflows but for those that work with particularly large models (Revit models in particular can be huge) or lots of applications at the same time, this could be a deal breaker. In comparison, a mainstream mobile workstation like the HP ZBook 15 G6 can support up to 128GB. To help deliver its compact form factor, the machine relies on a single M.2 SSD

With 4GB of GDDR5 memory, the AMD Radeon Pro WX 3200 is a step up from the 2GB AMD Radeon Pro WX 3100 that featured in the G5 edition. The additional 2GB should make a significant difference in certain applications when working with large datasets. Despite being an entry-level GPU, the Radeon Pro WX 3200 still performed very well with CAD and BIM software, even on our test machine’s 4K panel. In Autodesk Revit 2020, a BIM application that is notoriously CPU limited (i.e. the CPU can’t keep up with the GPU, so causing a bottleneck), 3D performance was similar to a workstation with a much more powerful GPU. This is simply because the GPU is underutilised. We observed that only 13% of GPU resources were used when moving a 4 million triangle building model on screen. In short, even if the HP ZBook 14u G6 did have a

f a s t e r GPU, you’d be unlikely to get any better 3D performance. Solidworks 2019 is also CPU limited, but nowhere near as much as Revit is. Using our 3.6 million triangle PC test assembly we got a fluid 22 frames per second (FPS) in shaded with edges mode and 13 FPS when we increased render quality by enabling shadows, RealView and Ambient Occlusion. This is on par September / October 2019

Review with more powerful GPUs such as the Radeon Pro WX 7100. When it comes to 3D performance, Solidworks is typical of most 3D CAD tools, but this is set to change in Solidworks 2020. The new release, due to launch soon, will feature a new graphics engine that is much less CPU limited because it offloads more of the graphics calculations to the GPU. As a result, it also uses more GPU memory, with medium to large assemblies typically using somewhere between 2GB and 4GB. The new OpenGL 4.5 graphics engine is currently available as a beta option in Solidworks 2019, which we used for testing. Performance immediately shot up to a silky smooth 43 FPS in shaded with edges mode. However, when RealView, shadows and Ambient Occlusion was enabled, performance dropped down to 12 FPS. With more powerful cards like the Radeon Pro WX 5100 and Radeon Pro WX 7100 you can expect 20-40 FPS, which gives a much better experience. This shows the Radeon Pro WX 3200 doesn’t really have the power to take on more demanding graphics tasks, especially at 4K (3,840 x 2,160) resolution. Rendering more pixels (4K has four times as many as FHD (1,920 x 1,080) generally puts a greater load on the GPU so this could influence your choice of panel. The laptop can be configured with a range of FHD or 4K IPS panels, some of which are touch-enabled. Two of the FHD models feature HP SureView, which is designed to combat what HP describes as ‘visual hacking’ (short for someone else looking at your screen) by significantly reducing the viewing angle at the touch of a button. To protect from prying eyes that might come from further afield, the HP Privacy Camera allows you to physically shut off the 720p / Infrared webcam. Our test machine came with an LEDbacklit 4K, 600 nits, 100% AdobeRGB panel. It’s a good quality bright display that delivers super sharp lines for precise

CAD work. Corner to corner it’s only 14-inches so you need to use Windows scaling in order to see text and icons. By default, this is set to 300%, although we found 200-225% offered a better balance. The machine can support up to two external displays via the HDMi or Thunderbolt 3 (USB 3.1) ports on the righthand side of the machine. Here you’ll also find a USB 3.1 Gen 1, Gb Ethernet, Docking Connector and SIM card slot (which works with the optional WWAN module). On the left-hand side there’s a USB 3.1 Gen 1 charging port and optional Smart card reader. WiFi and Bluetooth are delivered through an Intel Wifi6 AX200 802.11AX 2x2 +BT 5.0 Combo Adapter. The chassis is made from CNC machined aluminium and feels solid and well built. The full-sized backlit chicklet keyboard is pleasant to use. We experienced a little bit of give in the middle section, but only when pressing keys particularly hard. As you’d expect for a machine of this size, there’s no room for a numeric keypad. The touchpad is of a decent size and there’s also a Pointstick in the middle of the keyboard, for those that like their input devices ‘old school’.

Security conscious Like all of HP’s enterprise-class laptops, the ZBook 14u G6 is big on security. There’s a FingerPrint Sensor and Windows Hello technology for face authentication. These are standard fare, but HP also has some special technologies of its own. These include HP SureSense, an AIbased malware defence solution that is said to offer enhanced ransomware protection; HP SureClick, which puts all web browsing in a container so it will not infect the rest of the machine if an insecure website is visited; HP SureStart to protect the BIOS; HP SureRun to protect against an attacker turning off antivirus; and HP SureRecover, to help non-experts reimage a system on the go. Enterprise features also extend to

collaboration and the machine is ‘Skype for Business’ certified thanks to a ‘world facing’ microphone and dedicated buttons on the keyboard for answering calls, hanging up and presenting. The microphone (which is located on the back of the display) can be used in ‘conference mode’ so everyone in the room can be heard or ‘individual mode’ where it cancels out unwanted noise. Or you can simply plug in a headset. Battery life from the HP 3-cell 50 WHr Long Life Polymer battery is pretty decent, not least because the power demands from CPU and GPU are so low. The machine lasted 198 mins in the GPU and CPU hungry PC Mark test. Expect it to last significantly longer in less demanding workflows. HP Fast Charge support means it can charge from 0 to 50% in 30 minutes, which is useful for a quick top up in a coffee shop. As you might expect, the 65W Smart AC Adapter is very small, weighing a mere 300g with a US plug.

Conclusion The 14-inch mobile workstation used to be considered a companion product to a desktop workstation, to be used when away from the office. This is probably one of the reasons why the form factor has never really taken off, contributing to a very small proportion of mobile workstation sales over the years. But the HP ZBook 14u G6 is different to those that have come before. It is powerful enough for most mainstream 3D CAD and BIM workflows but significantly smaller and lighter than your average 15-inch mobile workstation. With tough competition from slimline 15-inch mobile workstations like the Dell Precision 5540, it’s unlikely to sell in huge numbers, but it promises to serve a niche market well. And for designers, engineers or architects who are frequently away from the office and place a huge value on portability, it’s an attractive machine for CAD on the go.

Scan 3XS WA4000 VR [3rd generation AMD Ryzen] It’s been a long time coming, but with AMD’s Zen 2, Intel is finally facing some serious competition. Greg Corke reports on Scan’s new Ryzen 3000 workstation Intel has dominated the workstation landscape for over a decade. Today, almost every new workstation comes with an Intel Core or Intel Xeon processor. You have to go back to 2006 for the last time AMD had a significant market share, when its Opteron CPUs were considerably faster than the Intel CPUs of the time. It didn’t take long for AMD to lose its performance crown and it has played second fiddle to Intel ever since. As a result, there’s been little incentive for any manufacturer to offer a workstation with an AMD CPU, let alone a major OEM. But things look to be changing. Last year, AMD caught Intel on the back foot with the launch of its 2nd generation Threadripper CPU. Based on AMD’s 12nm Zen+ architecture, the 32-core Threadripper 2990WX offered industryleading performance in multi-threaded applications – specifically, those that can take full advantage of multiple CPU cores, such as ray trace rendering. Zen+ also made some impact at the low end with AMD’s 2nd generation Ryzen CPU, which offered more cores than Intel at equivalent price points. But despite pushing Intel hard on multithreaded performance, AMD didn’t

Review completed the test in 80 secs and the Scan 3XS WI4000 Viz with an Intel Core i9 9900K (8 cores) (overclocked to 4.9GHz), which finished it in 75 secs. For another perspective on singlethreaded performance, we used the popular BIM tool, Autodesk Revit 2019. It completed the model creation part of the RFO Benchmark v3.2 in 105.9 secs. The HP Z2 Mini G4 did the same test in 100.6 secs – 5% faster. Unfortunately, we don’t have data for the Scan 3XS WI4000 Viz. This is not a full in-depth analysis by any means but, when comparing an overclocked 4.9GHz Core i7 9900K to an overclocked 4.3GHz AMD Ryzen 9 3900X, we reckon we’re talking about a 10% performance lead for Intel. And if you don’t overclock, and instead rely on the 4.6GHz boost, it could be considerably less. Either way it’s still significant, but it is dwarfed by the benefits the AMD chip can give you in multithreaded workflows. In the popular ray tracing application Luxion KeyShot, for example, it rendered our 4K test scene in 163 secs, 56% faster than the overclocked 4.9GHz Intel Core i9 9900K (8 cores). This puzzled us a bit as, theoretically, the performance benefit should be less than 50% as the AMD Ryzen 9 3900X only has 50% more cores and those cores are slower. In the V-Ray benchmark the Ryzen 9 3900X was 40% faster, which is more in line with what we expected. We imagine you’d have to go up to the 12-core Intel Core-i9 9920X to beat the AMD Ryzen 9 3900X in a rendering test, but as noted earlier such a chip would cost more than twice as much. As has come to be expected from Scan, we experienced relatively little fan noise

when rendering, even when running a KeyShot render for over an hour. This is down to the Corsair Hydro H100x liquid cooler, which packs dual 120mm fans and a 240mm radiator neatly at the top of the Corsair Carbide 275Q chassis.

Graphics tests The Nvidia Quadro RTX 5000 costs nearly five times as much as the Ryzen CPU and is a very serious graphics card. It’s the first time we’ve tested the desktop version and, unsurprisingly, it broke all of our benchmark records previously held by the Quadro RTX 4000. In Autodesk VRED Professional 2019, for example, we got an incredible 12.7 frames per second from our automotive test model at 4K resolution and with antialiasing set to ultra-high. That is 55% faster than the Quadro RTX 4000. At 4K with medium anti-aliasing, we got a silky smooth 33 FPS. The scores from VR Mark were similarly impressive. With the more demanding blue and cyan room tests, it was just over 40% faster than the Quadro RTX 4000. Of course, the Quadro RTX 5000 isn’t just about real-time 3D. It’s also a serious card for GPU rendering. In Solidworks Visualize 2019 with de-noising enabled, it was about 20% faster than an RTX 4000. However, in the V-Ray 1.08 benchmark, it only had a slender lead of 3%. It’s important to note that neither of these applications take advantage of the RTX ray tracing cores. This will come in Solidworks Visualize 2020 and a future version of V-Ray GPU.

Conclusion It’s hard to find fault with the Scan 3XS WA4000 VR. It offers incredible

performance and impressive acoustics. But the Quadro RTX 5000, which takes up the bulk of the £3,083 price tag, somewhat overshadows the real star of the show, which is the AMD Ryzen 9 3900X. For the first time since 2006, Intel looks to be facing some serious competition from AMD. Featuring 12 cores clocked at 4.3GHz, the Ryzen 9 3900X gives you the kind of multi-threaded performance previously only seen in CPUs that cost significantly more. And, most importantly, it does so without sacrificing singlethreaded performance. For around the same price, Scan offers an overclocked 4.9GHz Intel Core i9 9900K workstation. By choosing AMD over Intel, you’ll likely forgo around 10% of singlethreaded performance, but you should cut your render times by around 40-50%. For many, that will definitely be a sacrifice worth making. In addition, you could close the single-threaded performance gap by not overclocking all 12 cores and boosting single core frequency by 0.3GHz. We see the biggest opportunity for AMD and 3rd Gen Ryzen being with CAD users who rely on CPU renderers like Luxion KeyShot or those built into their workhorse CAD tool. So many designers, engineers and architects out there have workstations with four CPU cores. Investing in a new one with 12 cores at a similar price point is a huge step up. And when coupled with a CAD-focused GPU like the Quadro P1000, you can get a decent machine for just over £1,500. Scan is an incredibly agile workstation manufacturer, so we’re not surprised that it’s one of the first to take advantage of the new AMD chip. But on a global stage, its market share is incredibly small. For AMD to truly take the fight to Intel, it needs to land a major workstation OEM, like it did with HP and Siemens back in the mid-2000s. We’ve heard rumours that this could happen with Ryzen and, if it does, the increased competition with Intel can only be good news for the customer.
