Versprille: That is something outside of CAD, just as there is a lot of math software that can be used with CAD. Grabowski: Functional geometry has been around a long time, such as with Grasshopper. This is why generative design is popular again after having been invented 30 years ago. Q: IoT and AM have been trending on CAD for some time.Įvery example of additive manufacturing (AM) is coming out of generative design, which creates designs that cannot be made by subtractive manufacturing. I see a lot of possibilities for convergent modeling, more so than for generative design. Q: Does the definition of generative design include convergent modeling? Versprille: Autodesk and PTC are leaders in it, and actually are doing very well with SaaS. Q: SaaS for CAD is probably early days, with limited numbers of users. They have to pay attention to multi-threading and so on. Programmers of regular cloud software would have problems switching to programming cloudCAD, but programmers steeped in CAD would not. Versprille: I don’t think so, although CAD has some unique challenges that are different from regular software. Ralph Grabowski: CloudCAD is more difficult to implement than other kinds of software. Versprille: Definitely, although it may become cost-prohibitive, such as paying for going from ten CPUs to 20,000 CPUs. It is a technology-shift, not a CAD-shift. Ken Versprille: To me, mobile and cloud CAD are technologies which are the same at their foundation, whether on desktop, cloud, or mobile. Q: I don’t think we should lump mobileCAD with cloudCAD, because mobileCAD works offline. There is no change in the way CAD works when part of an IDP system. Artificial intelligence is logic added to CAD, such as improved feature recognition, prediction of next steps, and predictive selection. Yes: while MBD can be seen as simply applying GT&D to 3D models (so as to annotate 3D models instead of 2D drawings), it does change how designers interact with CAD models, and it causes the internal CAD data structures to change. Internet of things is more of a PLM trend than a CAD trend, but this may change in the future if IoT were to be integrated into CAD. No, for the same reason as SaaS: it is a software trend. Software as a service is just like desktop CAD but with subscription fees it is a software trend. ![]() No, not a trend: it is more of a software trend than a CAD-specific one. On the other hand, it is a trend, because of the way it allows mesh and solid geometry to work together, which is a CAD trend being worked on by Spatial in ACIS and Siemens in ParaSolids. ![]() ![]() On the one hand, it is not a trend because it simply automates the loop of how CAD has always operated: design -> analyze -> design -> analyze. The white box lists the trends that he discussed in the seminar.ĬAD trends of the current time Generative DesignĪ maybe-trend. Ken Versprille distinguishes between trends in CAD by asking, “Is it a CAD trend, or a software trend in general?” To be a legitimate trend, it should last more than a year, and it should change the internals of CAD, such as its file format or technology, or how the operator interacts with the software.Ī search of the Internet showed Mr Versprille a half-dozen topics considered by other commentators to be CAD trends as shown in the figure below. Understanding CAD trends is important today, because they will affect most CAD systems into the future. The subtitle has been "Real Change or Marketing Hype?"īy the day the seminar began, however, the title had changed to “A Totally Subjective View of CAD Technology Trends.” That was okay, because we still got to hear Ken Versprille’s opinions on CAD trends, and whether they really are trends in CAD. Issue #1,086 | The Business of CAD | 8 March 2021ĬIMdata held an online seminar to talk about CAD trends in 2021.
