Cover story: The future of Revit
The future of
Autodesk’s recent admission that there’s been a multi-year lack of development of Revit because of the concentration on cloud and construction has left many frustrated architectural practices wondering what the future of this 20 year-old BIM tool will be. Martyn Day examines the tea leaves
Autodesk acquired Revit Technology Corporation (RTC) with its Revit application in 2002 for $133 million cash. While RTC made a lot of noise, and its core parametric technology was innovative, it did not generate much revenue and, in fact, had few customers. Up to that point Autodesk had been trying to morph AutoCAD into a full-on architectural modelling tool with the unfeasibly complicated ‘Architectural Desktop’ variant.
One of the underlying key driving factors to the acquisition was that five years previously Autodesk dropped out of buying mechanical CAD (MCAD) tool Solidworks (Dassault Systèmes paid $310 million) which then went on to dominate desktop MCAD as users moved from UNIX to Windows.
Autodesk’s CEO at the time, Carl Bass, didn’t want to make the same mistake again. Had Autodesk bought Solidworks, it would not have spent millions on developing Inventor and then Fusion and would have been the number one player in desktop MCAD. The Revit acquisition protected Autodesk dominance in AEC and eventually proved to be a savvy investment.
The excitement of innovative code and doing things much better than previous generations of software is typically reserved for the early phases of development. Updates can be frequent and big; the potential can be seen. However, this furious initial phase typically slows down as a product ages and competition subsides. There is a lifecycle of software and to understand this better it helps if you can think a bit more like a software developer.
To generalise, the CAD software industry, on the micro scale, appears to have evolved to deliver the yearly evolution of authoring tools, executed on rolling 3 - 5 year development plans, along with equally evolving business models. For instance, we had perpetual licensing, where customers bought the perpetual right to access a version of software. Now the trend is for subscription licensing, where customers lease the right to use the software over a set time. The future looks to be heading towards a pay-peruse or subscription hybrid.
However, eventually software applications age; years of new layers of features compound to make products cluttered. The internal ‘wiring’ gets messy and fundamental changes can cause ‘regressions’ bugs in features that used to work but now don’t. At this point software companies need to make important decisions on how to maintain their success.
In the software world, a ten-year-old software program is deemed old. If a software package is extremely successful, the common-sense thing to do is to stretch it out and to do enough to retain the loyal base and keep the competition at bay. If

you do a good enough job, there are few, if any, competitors and software is ‘sticky’. But even here, at some point, software developers usually take the risk of writing something new from scratch, or they acquire a start-up that has done that work for them as it’s better for them to kill their most successful products, rather than have a competitor do it.
In this case, Autodesk decided to buy the next generation to kill Architectural Desktop, and switched BIM horses.
Development velocity If you want to understand where your chosen CAD product is in its lifespan, look at the development velocity. The less that is added each year, the more likely it is very mature. If new features appear to be ‘onion skins’ to the application, as opposed to fundamental core rewrites or big new dollops of functionality, it’s most likely that the team don’t want to dig into
the product’s guts for fear of playing Buckaroo with all the dependant code.
Another option is to redevelop applications on the fly, rewriting core features sequentially and doing a lot of under the bonnet work while keeping the same interface and file format – a case in point is ArchiCAD which had good multi-core support added at a platform level and AI added to rewritten features like the stair tool. While this may keep the code refreshed, fundamental principles remain the same and this can come unstuck if industry workflows change or a new upstart comes out without decades of baggage.
Moving to the macro level, every ten or twenty years the fundamental underlying technologies are renewed, and that could be hardware (like processors), operating system (DOS to Windows NT) or the change we see today, to cloud. At each of these technology boundaries, firms and market leading products can lose market share, even go extinct, if the software firms fail to manage the transition by having planned for change and being the best to leverage the new technology platform. This is why we are seeing so much concentration on, and development around, cloud-based apps, despite the majority of users being fairly happy on their desktop PCs.
Historic examples that spring to mind are PTC, which was the leading desktop MCAD player with UNIX-based Pro/ Engineer. It was severely mauled by the new Windows upstart Solidworks because PTC failed to get to Windows quickly enough and kept its prices high. Autodesk had a serious wobble when it went from AutoCAD R12 to AutoCAD R13, from DOS to Windows NT, completely rewriting the code in C++, adding in solids and then trying to build vertical applications on constantly-moving, buggy base code.

BricsCAD BIM
BIM that respects Design
If you want to construct something, you need to design it fi rst. You know this, and we know this – but it seems that other software vendors have completely forgotten about design and architecture. Bricsys has not forgotten – in fact, we live for this. BricsCAD® BIM is the modern, fl exible Building Information Modeling system that starts with BIM-ready modelling from the concept stage.
Start in solids with full freedom
Begin your design by sculpting freely, using our intuitive direct modelling engine. It keeps your BIM light and responsive and allows you to express your design without concern for families and classifi cations.
When you are ready, your study model becomes the BIM with the help of our A.I.-based workflows.
You can add detail continuously across the entire model with the help of these intelligent tools.
IFC
Interoperability
BricsCAD BIM is based on industry-standard DWG, to increase inter-operability and reduce overall training costs. It leverages the IFC open standards and is certifi ed by buildingSMART, so that interoperability is built into the core of BricsCAD BIM.
Fast and Stable
We take advantage of modern multi-core computer architectures, to ensure that you don’t need a wall of servers to enjoy our workfl ow.
“For engineers used to working in 2D, it is easier to start working in 3D with BricsCAD than with any other tool because you just follow the same intuitive pattern.”

Construction documentation
Unlike other BIM tools that seem to exist solely to create construction documentation, BricsCAD BIM makes the creation of annotative construction drawings a by-product of your design process.
We enable you to start with your art, and keep design “up-front”, from concept to deliverable.

Years away Reading this, Revit customers could be excused for wondering what on Earth is going on? Unless there has been a dramatic change of heart at Autodesk in the last week, there is no next version of Revit, no new generation, no fundamental rewrite. The Letters Group, while their input to the development has been welcomed, have had their expectations tempered to not to expect to see any radical rewrite of Revit.
Autodesk’s historic lack of Revit development seems to have many reasons, a switch to construction, a switch to developing cloud services, while maximising the amount of money it can get (and value for shareholders) for doing as little development work on Revit’s old code.
Thanks to the industry collectively calling Autodesk out, there will be some redress to the development and roadmap situation, a near-term win. This does not answer the long-term question of how can skilled architecture practices move beyond what’s possible today, when they feel limited by their 20-year old tool?
The lack of development and focus gave the distinct impression that Revit was in, at best, maintenance mode and raised the question of its imminent demise. Conversations with users tended towards reciting the Monty Python ‘Dead Parrot Sketch’. The reality according to Autodesk, is that it was ‘only resting’.
While ‘Plasma’ architecture might have a data back bone and new name now, it will be shown in some capacity at AU this year. However, this seems to be very early days and may well take a significant period of time to reach the market and then mainly for construction firms, not architects or design. The speed with which it can be brought to market will be a test for Autodesk’s Forge development system, which should enable accelerated delivery of tools and workflows, but as I said, this is a massive undertaking.
The Autodesk plan seems to be to try and keep Revit customers happier, in the meantime build the Construction Cloud, under the hood integrate Revit desktop subsystems to better work with its cloud services. Then over time, replace Revit with thick client applications for architecture, MEP and structural. My estimate is this could take a timeframe of six to eight years to complete. I do have serious concerns how the current Revit desktop, even with more development, can be stretched out to keep the attention of demanding architectural users.
Conclusion There is no Revit 2.0 and the future appears to be some kind of slow absorption into a cloud-based construction system with new thick client applications eventually replacing the single monolithic Revit application. Autodesk is technically ‘gapping’ between generations but is now desperate to try and reassure the Revit base that all is well. I’m not sure whether promising them that the same tool will be on Windows 2030 is an incentive to stay or go?
Autodesk’s development focus is clearly on construction; the plan for architectural seems amorphous and not fully fleshed out. Without the intervention of the Letters Group, I doubt we would have seen the Revit product owners so visibly engaging with their users.
With regards to licensing and costs, Autodesk has picked up that customers want pay per use (PPU). Looking at their current Token system, after 8 mins you get charged a whole day’s worth of tokens. 8 mins is the same as 23 hours, 59 mins 59 seconds. Most firms have Revit models that take upwards of 20 minutes to just load. So it costs a day’s worth of tokens to see your own model in Revit, let alone do any modelling.
In PPU I’m hoping that Autodesk is looking at better granularity on this, but I have concerns about cloud and PPU in general. Software companies will charge you to create your design, to store your design and then will make money from your supply chain accessing your design and using their tools on your data. Your data becomes a commodity in a pay to play system. This has all sorts of data protection and monetisation issues which need to be addressed.
This moment is clearly a time for architectural firms to reassess BIM strategy, its usage, the workflows, the workarounds, partnerships, deployment, product mix. I am seeing clear trends where architects are reclaiming the design portion of the process and pushing BIM tools to the documentation phase, almost to the extent that it becomes a discrete process.
BIM is too constraining for early stage design and seems to have not really delivered in automating the drawing process which was its main objective. From talking with the Letters Group it’s been really thought provoking discussing what comes next for design.
This is something that the Letters Group will cover in detail in an unmissable panel discussion that will take place during AEC Magazine‘s NXT BLD Virtual conference next month (8-14 October 2020 – register free at nxtbld.com).
In talking to Autodesk’s competitors over the last few weeks, many asked me, if Revit customers were so upset, why did they decided to write a letter and not just move to another system? It’s a good question. One of the firms involved in the open letter, described it as ‘having dug a hole so deep, that when you have serious concerns as to the direction you have travelled, and the costs now involved, you look up and see how far it is to get out, and the question is, whether you should climb out of the hole and start again, or keep on digging, in case it gets better.’ In many respects, the multitude of issues that the Open Letters group addresses take this beyond wanting a better Revit, it wants a better Autodesk.
