Microsoft launches HoloLens 2, enhancing mixed reality for construction ast month at the Mobile World Congress in Barcelona, Microsoft unveiled HoloLens 2, its much anticipated next generation wearable holographic computer. Microsoft was joined by Bentley Systems who showed how with its Synchro XR for HoloLens 2 software, users can interact collaboratively with digital construction models to plan, visualise, and experience construction sequencing. HoloLens 2 features more than double the field of view than the original mixed reality device, which many found to be a significant limitation. There’s also a new visual display system, which Microsoft says makes the holograms even more vibrant and realistic. The updated device includes new eyetracking sensors that are designed to make interacting with holograms even more natural. For example, when someone’s eyes land on a particular part of a machine, it can call up useful digital information about it. Interaction with holograms has also been made easier. With natural hand tracking, users can now grab and rotate them as they would a real-world object, rather than having to learn gestures that mimic mouse movements. HoloLens 2 also includes iris recognition with Windows Hello authentication to make it easier for multiple users to log in and share the device. A new flip-up visor lets users switch easily between physical and holographic worlds. Comfort has also been addressed. Microsoft says the new dial-in fit system makes the HoloLens 2 comfortable to wear for ‘hours on end’. Users can also wear glasses with the mixed reality headset because it now adapts by sliding right over them. In terms of practical applications for construction, Bentley Systems showed how a project digital twin can be visualised with the HoloLens 2 via Bentley’s connected data environment, powered by Microsoft Azure. With the mixed reality solution, construction managers, project schedulers, owner operators, and other project stakeholders can gain insights through immersive visualisation into planned work, construction progress, potential site risks,

From Quantum to Plasma Autodesk seeks to reinvent collaborative BIM In 2016, Autodesk announced Project Quantum, described as a platform technology for “evolving the way BIM works, in the era of the cloud, by providing a common data environment”.

components that needed to be manufactured by better adapted CAD systems. This meant that different professionals in the workflow could all have different versions of the same model, but they were connected by a common platform. What’s more, live geometry could be pumped around the system in real time for teams to see the model in various levels of detail. This was indeed a brave new world and it seemingly was a very slick way of introducing a change in the way BIM would touch every player in a federated AEC project. Unfortunately, company politics intervened, Hanspal left Autodesk after the company’s board chose Andrew Anaganost as new CEO, and news on Quantum went dark. Roll forward to Autodesk University 2018 and in one of those corridor conversations that happen by happenstance, AEC Magazine learned that Quantum had indeed survived but had actually been a victim of its own success. The technology was deemed to be so useful that the company decided to take a broader view of its potential to all products and verticals (e.g. AEC, manufacturing) and so paused to take in more internal stakeholders into its development as a platform technology. The net result is Project Plasma.
Awe inspiring Earlier this year, AEC Magazine had the opportunity to talk with Autodesk’s chief www.AECmag.com

software architect, Jim Awe, about the name change and the company’s vision for Plasma and its capabilities. Awe explained, “What happened was, the idea of quantum, and doing automated workflows in a trusted way gained momentum. As we talked to customers, they definitely supported that idea and that was crucial to moving project collaboration forward. Then when we started to talk to other people around the company, we found that the manufacturing group were facing the exact same problem. “Autodesk has traditionally been a design-based company and the goal of most of the products like Revit were to produce construction documents and then ‘throw them over the wall’ and have someone figure out how to make it. It turns out, manufacturing had the same issue, that they design everything upfront and then had to figure out which tools on the factory floor were going to make different parts of the assembly. They did the same thing and would break up the model, divide it up between multiple people who would figure out how to make their part in the process. “This is a strategic shift. It’s not good enough to just design something, you have to be able to make it and in order to do that, you need a workflow that goes throughout the project life-cycle. This technology [Plasma] should be in the platform and so it became a much bigger, more elaborate, effort. We’re are taking our time
to get it right because it’s so important.” We asked Awe, how the platform worked, “The best analogy which describes what we’re trying to do here, is if you look at what Apple did with iOS. Apple has a platform, where you can build an App and plug into well-known services of the iOS system and then construct a mobile workflow. The App hands off the GPS location to maps, and photos are integrated into other workflows, all on your mobile device. We need to integrate enough of the pieces so that when you try and move data from, say Revit to a fabrication phase, you are moving the appropriate amount of data and the person on the other end knows where to find it and absorb it into their workflow. “Carrying on with the Apple iOS analogy, we will definitely build some of our own applications plugged into this and we fully expect some of our Forge partners to hook up into Plamsa in lots of interesting ways. “All the professional and IP boundaries are maintained with the data that is flowing between collaborators; it’s tracked, it’s scoped, so you’re not just sending the entire model across. In most instances it’s more likely to be a subset of it.” Autodesk is calling this data exchange a form of a ‘data contract’, so users decide what limited data they want to share with each project participant and the system tracks and approves the exchange, as it goes through a series of March / April 2019

‘gates’. This means control is maintained by each of the originators in a project, sharing data which can’t be edited, so while the structural engineer can see the architectural elements, she can’t change components that the architect is responsible for and vice versa.
Blockchain. We are currently exploring how to secure the legal part of the system. “If you look at the progression of how were trying to deliver this, the theory is the legal part. The implementation, so far, has focused on the data interoperability piece, which is what and how do you get the data automated in and out of the application. How do you construct a workflow that will spin up all the right compute nodes and send the proper notifications? The mechanism is now in place, but we have not yet figured out the legal side as to how these transactions don’t get tampered with. We also have to work out what legal exposure Autodesk has in providing this service! “This is more than just technology, it’s Autodesk looking at who is going to be responsible for that Escrow. There are a couple of options; Autodesk could decide to take responsibility, or maybe create a spin-off entity, or we could put the onus on the owner, or concede it to something like blockchain and have a technology solution, where nobody needs to be responsible as a technology is taking care

quently. If a user hits Undo in Revit, it will only Undo the work they have done in their model, but users can roll back to a previous version of the Data Contract. Users can see what receiving versions of the Data Contract had on their model. It’s possible to play through all of the decisions in the lifecycle of a design and even go back to a previous version of the Data Contract and start modelling from there or replay through all the data that came through those gates. According to Awe, Branching and Merging are built into the underlying database technology, “We do use it in the Escrow system and the contract definition,” he says. “However, if users want to have that same technology in a core application like Revit, then that’s a different story. Revit wasn’t built that way. Revit could start making use of that facility in the database and we’ve done some experiments, but we haven’t decided if we are going to go back and re-engineer those applications.”
theory out, ten years down the road, ideally Revit would also be able to decouple every system in the building and say I don’t need to model the entire thing myself, I just need to coordinate with someone else who’s modelling that piece. “You could basically divide Revit up into more specialised modellers for the specific systems but still coordinate between the different disciplines. But right now, Revit is taking on that responsibility and doing all the coordination itself. Plasma enables the single version of the truth. However, it is essentially distributed. Each app, each persona in the ecosystem is able to maintain the model that makes the most sense to them and then communicates the part that needs to have a collective sense of the overall model for collective co-ordination.”
Conclusion
Our initial hopes of Quantum being the next generation of Revit in some ways have drowned in the sea of automated collaboration. However, we now realise that the whole concept of applications, especially desktop ones is somewhat mute in the world of cloud-based workflows. Not unlike the end of The Avengers: Infinity War, we see desktop apps and workflows turning to dust in slow motion. Project Plasma is a total rethink of data flows in a cloud-enabled world. It’s Autodesk recognising that one application cannot be infinitely expanded to solve all upstream and downstream problems in digital design workflows – an outlook that in its previous life, Autodesk tried to drive home every nail with an AutoCAD shaped hammer.

hat does BIM have to do with building maintenance or safety? Often the answer is, not enough! As we are making the migration to the digital BIM workflow, we’re building a mountain of valuable graphics and data; the challenge is, how to squeeze all the value from this new resource? Could it be that BIM might be the solution to some of the ageold problems, like engaging with building users, operators and maintainers?
Constructing a building is no easy feat, there are lots of competing interests to consider and lots of processes to manage. It’s little wonder that sometimes we don’t have enough time to think about maintenance. The case we’d like to set out here, is that using BIM makes it much easier to get people thinking about maintainability. We’d like to run through a very simple example of a difficult to maintain element and make an argument for why a modelbased construction design and manage-
ment (CDM) walkthrough may have given the opportunity to design out this issue. Annoyingly, a light in the atrium, as shown in figure 1, has failed. Is that a big deal? It’s just one light at the University of the West of England (UWE) Bristol where we have 300,000m² of internal space and do around 2,000 lamping replacements a year. As it happens, this particular fitting does cause a fair amount of upheaval. The only way to access it is using a spe-

any asset,” says Jan-Willem Koutstaal, Bentley vice president of local account initiatives, and the former CEO of Plaxis. “Fundamental to any decision you’re going to make on a change in that asset is going to be the geotechnical engineering. “You use software to assess the initial ground conditions, to understand what you are going to be building on top of, but then throughout the lifecycle of the building you are doing regular observation through sensors in the foundations or building, or surveying with drones.” The idea here, is that by embedding sensors into the asset or creating reality models through ContextCapture, data can be continuously fed into the software so it can automatically re-analyse the asset based on its changing conditions over time. Such changes could be dictated by subsidence, seismic activity or weather, but there could also be changes in owner requirements or structural strategies. Importantly, the digital twin could also be used to help predict what might happen in the future. Koutstaal explains that in such a system a green light could denote “you’re OK at the moment,” but if the movement carries on at a certain rate
you’ll get orange, a critical state. This type of predictive analysis could be augmented by deep learning, based on what has happened in the past, either on the same structure or on different structures. The software could then put forward multiple “what if” scenarios, leading to recommendations for pre-emptive action to be taken. In the most extreme cases this could help prevent catastrophic failure.
Conclusion Bentley is long established in the engineering of structures above ground. Now, with its acquisition of Plaxis, it’s looking to do the same below, introducing advanced geotechnical engineering technology to its global customer base. Marrying the two, previously independent worlds of simulation, is an obvious path for Bentley to take, to streamline workflows and to deliver more accurate results, but arguably the biggest
prize will be in applying geotechnical engineering to digital twins. The concept here is that the asset owner will not only have a digital twin of the infrastructure itself, but of the geotechnical conditions that surround it. And over time, the owner will be able to assess the impact of the changing environment and predict well in advance when maintenance or critical action might be required. It’s a bold vision, and one that becomes even more compelling when you consider that it could save lives. ■ bentley.com

Minimising movement Another issue faced by structural engineers when designing a façade retention scheme of this scale is deflection, as too little stiffness could result in the excessive movement of frames, and consequently even structural damage to the façade itself - a serious concern when the building is located in a busy London shopping district and falls within a conservation area. “The design for this project was deflection critical, meaning that the deflection of horizontal trusses, vertical frames and transfer systems had to all be considered,” says Vaughan. “Thankfully Tekla Structural Designer was able to model and analyse all of these conditions, enabling us to consider the 3D frame effects of the retention scheme, rather than relying on a simple 2D analysis. Working in 3D, we were also able to optimise the weight of the retention structure, reducing the amount of steelwork required and saving both time and money.”
porary structure is absolutely imperative,” explains Vaughan. “However, this can prove difficult, as many of the retention scheme connections are unique and will involve the design of non-standard elements and supports. It is therefore critical that they are correctly understood by the modelling software when detailing. “Fortunately, Tekla Structural Designer was able to analyse the steel frame and load paths while also ensuring positional coordination with the existing façade, reducing the risk of clashes or need for re-work on site.” Furthermore, WHP was able to easily update and analyse the model whenever changes were required by the client, both during and after the design process, ensuring that the overall structural system wasn’t compromised by any such changes. Tekla Structures was also used on the project, with information easily coordi-
nated and transferred between the structural BIM tool and Tekla Structural Designer. This compatibility enabled WHP to prepare fabrication drawings in Tekla Structures using data generated by Tekla Structural Designer, ensuring that the steel connections used in the retention scheme would be accurately manufactured in accordance with the design and eliminated the approval cycle that would have occurred had the fabricator prepared the drawings. “Using Tekla Structural Designer and 3D modelling helped us overcome the numerous challenges and constraints that this prestigious project presented,” concludes Vaughan. “It helped us accurately and precisely analyse highly complex and variable frame, ensuring viable load paths in a complex location whilst also minimising weight and ensuring coordination with the existing façade.” ■ tekla.com
Clash detection One of the well-documented benefits of BIM and Tekla Software is its automatic clash detection. Rather than hand-drawn 2D drawings where clashes could pass undetected until construction had begun, resulting in costly re-work and delays, 3D modelling can alert engineers to clashes at the design stage, helping mitigate errors and streamline the design process. As well as considering clashes within the retention structure itself, the retention steelwork on the Knightsbridge Estate project also had to be precisely coordinated with the existing building façade. “For façade retention, ensuring coordination between the existing and the tem28

or centuries, construction has been done in much the same way: brick by brick, girder by girder, slab by slab—first by human hands alone, then with the help of machines. Even as our structures and our design ambitions have soared, the processes used to make those designs real have remained stubbornly stuck in the past. But with Building Information Modelling (BIM) and innovations in digital fabrication, new possibilities and efficiencies emerge. Today, new kinds of materials and methods are changing both what we build and how we build it. Intelligent robots and other kinds of automation can now safely work side-by-side with people, even on construction sites that are constantly changing. And large-scale 3D printing operations positioned on or near the site can deliver custom components for construction on demand (tinyurl.com/AU-3Dprint). Manufacturing has been making huge leaps forward in efficiency for more than a century. While construction has lagged behind, digital fabrication techniques give us new tools to bridge the gap. The secret? Keeping data at the centre of the process. Check out these Autodesk University (AU)

Opinion
ISO 19650: going global part II In the second and final installment of this article on ISO 19650, Rebecca De Cicco explains why the UK is benefiting most from the practical application of the new standard We have seen much momentum since the release of both the international and British versions of ISO 19650. This is an exciting time for our industry as finally a global solution for BIM is now available. Regions with little or no guidance are beginning to utilise new BIM processes and adopt a common language. With the British standards being used as a foundation for the development of the ISO, there is much to look forward to when it comes to its future use in the UK. What excites me the most, is that we have a world of opportunity ahead of us as a global industry, where we’ll see regions with little to no standards trying to adopt new processes they know very little about. The uptake on the use of PAS 1192-2 and 3 in regions such as Australia and China for example, was an excellent start, which can only grow further now we have the ISO. However, even though there is an understanding of the importance of the standards, no official mandate exists in these other countries like it does in the UK therefore gaining mass buy-in will be challenging – but we’re ready to take on that challenge! It will be an interesting journey to see the implementation of ISO 19650 across the world and although we don’t have clear visibility across every region when it comes to BIM implementation, we still understand that consistency in language, process and information delivered intelligently is crucial. Here is my observation of where we are globally and why the disadvantages of other regions are proving to be a massive advantage to the UK, with expertise export opportunities now on our doorstep for UK BIM professionals to support other regions in their BIM adoption journey.

date. Therefore, due to our understanding and regular use of the 1192 suite of standards, the transition to ISO (it is presumed) will be a smooth one. This is also supported by the fact that the UK is the first region to release the British Standards / CEN version of the ISO and to develop the very first regional annex. The same ease of ISO implementation sadly cannot be said for a global roll-out. Much of the regional development in BIM outside of the UK is being haltered by jurisdiction as well as historical context and we’re seeing a very disjointed approach toward the uptake and use, as well as understanding of BIM according to ISO 19650. There are small pockets of BIM enthusiasts driving the BIM agenda in many different regions, however a formalised incentive is needed.

regions. This is why we believe uptake in the US will initially be slow when it comes to the use of the ISO but for Canada things are a little more positive. Canada is already using UK methods and products such as the NBS BIM Library and this is very much true for Australia too. There are also huge opportunities in China, as we see Hong Kong leading the way nationally with the development of local BIM standards and certification for BIM professionals. These projects have been influenced by the local authorities (Construction Industry Council in Hong Kong) which have taken much of the guidance from British Standards. Much work is now being undertaken to internationalise these products with the release of ISO 19650. UK businesses will begin to see the benefits of the ISO being implemented globally as specialised knowledge and skill will be required to support these types of initiatives.
BIM knowledge is extremely varied from region to region with a distinct lack of consistency in process.

Visualisation expert Visual Trick went into extreme detail for a recent project in leafy East Sussex as the project set out to add a new build to this rural lakeside location. The developer of Hook Place was looking to secure ‘Para 79’ status (shorthand for the special circumstance set out in criterion of (e) paragraph 79 of the NPPF 2018) to allow new isolated homes to be built in the countryside, subject to certain requirements. www.AECmag.com

As a result, photorealism in presentation of the structure, showing how it would blend with the surrounding landscape and vegetation was of the highest importance. The plant species to be used, their relationship with the countryside area, the choice of the materials and the appearance of the building in this particular context all had to be on the money. Visual Trick began the project like it www.AECmag.com

does all others — the client was asked to send over all the drawing, surveys, photographs and sketches necessary to understand the projects and the needs, but also to advise the best route to take. A 3D model of the elegantly curving structure was created in SketchUp, allowing for camera framing to take place early and to establish the final composition for each visual.

Hrvoje Cop, CTO of leading Croatian visualisation studio Polymachine, shares details of four recent projects, focusing on composition, visual accuracy and the benefits of keeping everything in 3D
These images are part of a larger project we did for a manufacturer of designer furniture, and the purpose was not only to produce marketing imagery, but also to create a library of high-quality 3D models for the entire product range. Needless to say, accuracy of was of paramount importance, so no effort was spared to get the proportions and materials as close to the real thing as possible. Once that phase was completed, we tried to create an environment which brought out the best from the products themselves while trying not to overpower their presence in the final images. Special attention was given to the background forest which is fully 3D modelled, because we felt compositing a photo would neither do the space justice, nor feel natural in the overall composition

Much like the previous two images, the biggest challenge here was to figure out a way of creating a flattering environment, but still have the product stand out. Once again, after the scene was finished, we decided to model the background building in 3D as well. With shots that rely on camera depth-offield, however subtle it may be, keeping everything in 3D allows for a much more balanced, and visually pleasing result
(Right) Close-ups are always great fun to work on, because you can focus on details which are usually not visible in wider camera angles. With less elements to the image, composition and the relationship between the individual elements play a vital role. Today’s render engines make a spectacular job of capturing the subtle nuances of surface materials, and close up shots like this can use that to great effect

We could not gain access to aerial photography of the plot for the desired views, so we ended up simulating a large stretch of the sea. Since fluid simulation is much more often used in movies than architectural visualisation, it was a great chance to learn and explore aspects of CG which are rarely used in our daily work

Nvidia Quadro RTX 4000 Nvidia’s new Quadro GPU is a phenomenal proposition for real-time 3D graphics and VR and, with the potential it has for GPU rendering, it would be a real waste not to harness its power for ray tracing as well, writes Greg Corke Price £808 Ex VAT pny.eu
which could be used for 3D graphics or other parallel processing tasks such as ray trace rendering or simulation. Quadro RTX still has thousands of CUDA cores, so it can do all the things that Pascal and Maxwell could do (albeit faster), but it also features two additional sets of cores: RT Cores, which are optimised for ray tracing; and Tensor Cores, which are optimised for deep learning. In order to take advantage of these optimised cores, software has to be specifically written to do so. And while there is widespread commitment from the industry, including Chaos Group (V-Ray), Solidworks (Visualize) and Luxion (KeyShot) to name but a few, it will take time for commercial software to be released. So where does this leave us? At the moment, anyone investing in a Quadro RTX GPU can only use it in the same way they have used previous Quadro GPUs – just using its CUDA cores. But the good news is, because the new Quadro RTX GPUs are a significant improvement over previous generations, this will be reason enough for many. Then, when Quadro RTX-enabled software finally starts to ship, design viz folks will be able to generate photorealistic output even faster.
workstation. This is done through NVlink, a proprietary Nvidia technology that is supported on the RTX 5000 and above. Those who can afford two Quadro RTX 8000s, for example, can effectively have a GPU with a colossal 96GB. With this amount of memory, Nvidia really can start to compete with the massively scaleable CPU architecture. As you can imagine, the higher up the range you go, the more cores you get (CUDA, Tensor and RT). All GPUs are rated by FP32 performance, a measure of their single precision compute capabilities (TFLOPs), based on their CUDA cores alone. This figure can be compared directly to previous-generation Quadro products. Nvidia has also introduced two new metrics to help users differentiate between its new GPUs. The first is RTX-OPS, which takes into account general processing power as well as the GPU’s ray tracing and deep learning capabilities. The second is Rays Cast, a specific ray tracing metric measured in Giga Rays/Sec. It’s important to note that the Quadro RTX GPUs are more power-hungry than the Pascal Quadros they replace. The max power consumption for the RTX 4000, for example is 160W, compared to the 105W of the Quadro P4000. The top-end RTX 8000 can go all the way up to 295W. DisplayPort 1.4 is standard across all four Quadro RTX GPUs. Also included is VirtualLink, a new open standard that can deliver power, display and data for nextgeneration VR headsets through a single USB Type-C connector.
Ever since Nvidia unveiled its Quadro RTX ray tracing GPUs last year, the design viz community has hotly anticipated their arrival. And that’s hardly surprising: the Unreal Engine demos, featuring stormtroopers and a Porsche 911 Speedster concept car, were quite breathtaking. Producing a single ray traced quality photoreal image used to take seconds or even minutes, but this was now being done in a fraction of a second on a desktop workstation, albeit one with two very powerful GPUs. Nvidia had shown it could make photorealistic visualisation completely interactive and while there was almost certainly some smoke and mirrors, it marked a massive The Quadro RTX family advancement. Nvidia has launched four Quadro RTX Fast forward six months and design viz GPUs, from the mid-range to the high end. artists can now start to see what all the We imagine Nvidia will launch lower-end fuss was about — well, kind of.

It offers several levels of real time anti-aliasing (AA), which is important for automotive styling, as it smoothes the edges of body panels, but AA calculations use a lot of GPU resources, both in terms of cores and memory. We tested our automotive model with AA set to ‘off’, ‘medium’ and ‘ultra-high’. The Quadro RTX 4000 was significantly faster than all of the other GPUs, but its advantage over the AMD Radeon Pro WX 8200 became even clearer when real-time AA was enabled (see charts 3, 4 & 5). At 4K, with AA set to medium, the RTX 4000 was the only GPU to give what we would describe as a fluent experience, only a touch below the ideal minimum of 24 FPS. However, when AA was set to ultra-high, even the RTX 4000 struggled, and the model was quite choppy in the viewport.

Review ten years now. But 2019 could be the year that it really comes of age. While most of the renderers built into CAD and BIM applications still rely on the CPU, there are a growing number of impressive GPU renderers. These include V-Ray NEXT GPU, Solidworks Visualize, Siemens Lightworks, Lumiscaphe, Catia Live Rendering or any renderer that uses Nvidia Iray. Even Luxion KeyShot, a die-hard CPU renderer and one that is particularly popular with product designers, was recently demonstrated running on Nvidia GPUs.
we used Solidworks Visualize 2019 SP1 instead. This version doesn’t support Nvidia RT cores and can only utilise the GPU’s Nvidia CUDA cores. Even though the Quadro RTX 4000 was not being used to its full potential, it was still incredibly fast at rendering. We started with the stock 1969 Camaro car model at 4K resolution with two different quality settings: first, at fast quality with 100 passes (see chart 11), enough to get a good test render; second, at accurate quality with 500 passes, which delivered significantly better results.
with Solidworks Visualize. However, this could change in the future, as AMD recently demonstrated a technology preview of Solidworks Visualize accelerated on Radeon Pro GPUs. Solidworks Visualize 2019 may not be able to harness the full capabilities of the RTX 4000 GPU quite yet, but it does have some tricks up its sleeve. The GPU can be used for artificial intelligence (AI) denoising to significantly reduce the time it takes to produce rendering output. AI denoising works by rendering a scene with fewer light ray bounces, resulting in a grainy Solidworks Visualize image, then using deep For our tests, we focused learning to filter out the GPU rendering is nothing new; we’ve been predominantly on noise. Having learnt from writing about it in this magazine for ten years Solidworks Visualize. thousands of image pairs now. But thanks to GPUs like the RTX 4000 The name of this GPU(where one of each pair is accelerated physically- 2019 could be the year that it really comes of age noisy and the other is fully based renderer is a bit rendered), it essentially misleading, as it works predicts what the final with many more applications than the The RTX 4000 delivered its 100 image would have looked like if it had been CAD application of the same name.

It completed that job in just over half denoiser, then you may be able to achieve At Solidworks World in February, the time it took the Quadro P4000 and the same rendering quality with 50 passes there was a demo of a tech preview of just under a third of the time it took the with the denoiser enabled.

rendering at 10k resolution. We then imported the MaunaKea Spectroscopic Explorer assembly, hit render, and it immediately fell back to CPU. In fact, this model is so big that we couldn’t even get it to render on the 16GB Quadro P5000. There are no hard and fast rules here as to what the RTX 4000 will be able to handle in Solidworks Visualize or other GPU renderers, but if you’re currently pushing the limits of other 8GB GPUs, such as the Quadro M4000 or P4000, then you’ll probably need to look at the 16GB Quadro RTX 5000 or even higher. Alternatively, you’ll need to get smarter about how you optimise scenes.
Multitasking One of the big challenges of giving the GPU more responsibility, and the ability to perform graphics and compute tasks at the same time, is that different applications will start to fight for finite resources. If you’re running a GPU render in the background, for example, but also need to spin a model in the CAD viewport, something has to give. Compared to AMD, Nvidia hasn’t historically fared so well in multitasking workflows like this, but has this changed with the RTX 4000? To find out, we set a render going in Solidworks Visualize, then loaded up the colossal MaunaKea Spectroscopic Explorer telescope assembly in Solidworks 2019, using the new OpenGL 4.5 beta graphics engine. When panning, zooming and rotating, everything felt really responsive, which wasn’t always the case with the Quadro P4000. Viewport performance did drop — from 41 FPS to 25 FPS, but this didn’t impact our experience in any way. We upped the ante with Autodesk VRED, which demands even more from the GPU, but again everything www.AECmag.com

Scan 3XS WI4000 Viz This desktop workstation packs a big punch for real-time viz, VR and GPU rendering, and it’s no slouch when it comes to CPU-intensive workflows, writes Greg Corke Price £1,463 Ex VAT hp.com/zworkstation
The CAD workstation has had a pretty standard template for some time now — high frequency quad-core or six-core CPU, mid-range pro GPU, 32GB of RAM and an SSD. Of course, this spec is fluid and can be adjusted as required. For workflows that include real-time viz or VR, for example, you’ll need a more powerful GPU; for quicker ray trace rendering, a CPU with more cores. And if you do both, a bigger investment in both areas. With the rise of GPU rendering, however, things are starting to change. Firms can now put the lion’s share of their budget into the GPU to solve most of their computational demands and stick with a relatively cheap CPU. This is all great in theory, providing your ray trace rendering software of choice runs on the GPU. But this still isn’t always the case. Most renderers built into CAD and BIM tools still run on the CPU. Scan’s new 3XS WI4000 Viz workstation finds some middle ground, coupling the relatively low-cost eightcore Intel Core i9 9900K CPU with the phenomenally powerful Quadro RTX 4000 GPU. The result is an incredibly fast desktop workstation that can do most of what your average product designer will need for real-time viz, VR and GPU rendering, and all for under £2,000.
Eight-core power Until recently, eight-core CPUs came at a big premium, but the new Intel Core i9 9900K delivers this spec for a very palatable £417, a mere £84 more than the CAD-standard six-core Intel Core i7 8700K. Out of the box, the Core i9 9900K has a base frequency of 3.60GHz and a Max Turbo of 5.0GHz, but Scan has applied its overclocking expertise to deliver all eight cores at a phenomenal 4.90GHz. For single-threaded CAD and BIM applications, it doesn’t get much faster than this. In Solidworks, the machine felt www.AECmag.com

Review
HP Z2 Mini G4 With a high frequency 6-core Intel Xeon CPU and several GPU options, HP’s updated micro workstation is a great alternative to a standard CAD desktop, writes Greg Corke Price £1,463 Ex VAT hp.com/zworkstation
In late 2016 HP broke the mould with a desktop workstation that was significantly smaller than any other from a major manufacturer. The HP Z2 Mini delivered pretty much everything you’d want from an entry-level workstation for CAD or BIM workflows, but the stylish, angular chassis was only 216mm (w) x 216mm (d) x 58 mm (h) in size. HP’s space saving workstation looked great on any desk. It could also be mounted under a desk, behind a display, or on a wall, housed in a metal sleeve. It was ideal for small spaces and you could also take it home or to meetings. Read our full review at tinyurl.com/z2-AEC. The second-generation HP Z2 (actually called the G4 Edition to get in sync with other HP Z Workstation release cycles) includes some small, but significant tweaks, mostly around the kit that’s inside. The big news is the inclusion of the new “Coffee Lake” Intel Xeon E-2100 CPUs, which feature up to six cores and clock speeds of up to 4.70 GHz. Four CPU cores has been the standard in entry-level workstations for over 10 years, so the move to six cores is a big step up for engineering or architecture firms that rely on CAD or BIM software, as well as multi-threaded ray trace renderers. The flagship CPU on offer is the Intel Xeon E-2176G, which features six cores, a base frequency of 3.70 GHz and a Max Turbo of 4.70 GHz. This is pretty much the fastest Xeon processor you can get for single threaded applications, such as 3D CAD. It’s also a significant step up from the HP Z2 G3’s top-end Xeon E3-1245 v5, which has four cores, a base frequency of 3.50 GHz and Max Turbo of 3.90 GHz. The additional 0.8GHz will make a noticeable difference in CAD / BIM and the six cores should cut render times considerably. The HP Z2 G4 also offers several 8th Generation Intel Core processors and, for those on a really tight budget, an 8th generation Intel Core i3 and Pentium. 50

With 16GB (2 x 8GB) of DDR4 memory, our test machine is only really equipped for moderate 3D datasets, but the Z2 Mini can be configured with up to 32GB. For storage, there’s the classic combination of 256GB M.2 NVMe SSD (HP Z Turbo Drive) for OS and applications and 1TB 2.5-inch HDD for data.
Conclusion In Autodesk Revit and Solidworks, 3D performance was pretty good. In these notoriously CPU bound applications, the HP Z2 Mini benefits from the high frequency CPU, which pushes up frame rates. And you wouldn’t get much better from a more powerful GPU. Switching to the new beta graphics engine in Solidworks 2019 generally gave a very fluid viewport experience, even with fairly large assemblies. However, when pushing the GPU much harder in the viz-focused Enscape, performance was less impressive, but that wasn’t unexpected for such an entry-
The HP Z2 Mini G4 is a worthy successor to the G3 edition. You get the same stylish, space saving design at a similar price point, but with potentially 50% more CPU cores at higher frequencies. This leads to clear benefits in single threaded CAD / BIM software and multi-threaded rendering software. The HP Z2 Mini is not the only micro workstation out there (we’re also big fans of the minuscule Lenovo ThinkStation P330) but it’s certainly the fastest. It offers similar levels of performance one can expect from a Small Form Factor tower but with much less bulk. www.AECmag.com
