When my friends here at SpaceClaim asked me to take a look at their new system, I was both excited and hesitant. Excited, because I knew this team well (these guys are the real deal IMHO) and I wanted to know what they were up to. But at the same time, even though I had been watching the CAD industry from the sidelines for a few years (after spending the previous 17 in the industry), even I knew that the world didn't need another CAD system. How was I going to tell them?
My first visit to SpaceClaim earlier this summer reminded me of the first time I saw Pro/E (back in 1988 at a trade show) and I asked the A/E giving the demo to change a bolt hole circle from 3 holes to 4 holes, and the bolt hole circle actually changed from 3 holes to 4 and the spacing changed from 120 to 90! This was unheard of in CAD at the time - intelligent changes that caused new features to be created. Next thing I knew I was employee number 72 at PTC.
With SpaceClaim, it turns out my excitement was justified, and my hesitation wasn't. Why? Well, much to my relief, they aren't trying to build the “world's next great CAD system.” Instead, they are trying to solve a very specific problem: import any CAD model from any system, and then easily take it into any new direction, unconstrained by the features and parent / child relationships in the source model, and make it easy for regular people to use.
I am excited that these guys are solving a very real problem. And I'm happy that they aren't trying to convince (me and) the rest of the world that their way of building CAD models is the “right” way to do it.
Universal import and modify might just be the new holy grail. I think this is a pain point that the entire industry feels. We live in a heterogeneous CAD world. There are a ton of use cases both for simplifying and iterating on models for downstream processes like FEA, CAM, collaboration and real time changes at design reviews, etc. It's also a nice tool for the “dedicated CAD users” to have in their toolbox so they can get “unstuck” when they're in the occasional jam.
So what do I think SpaceClaim is doing right?
Import. They've got direct native translators for just about every system and format.
History free. I don't believe that history free modeling is the right approach for all tasks. (In fact, I personally prefer parametric feature based tools for building models from scratch. Throw in a couple of family tables and it becomes a no-brainer call for parametric modeling.) But for modifying existing models? This is very cool and powerful stuff.
UI. SpaceClaim is clearly not trying to be a replacement CAD system. Look at the commands. Things like Pull, Move, and Trim. There is no Feature/Create/Protrusion. This is a tool that was built for modifying models. The UI is very slick. I really can see non-CAD folks using this thing.
Dynamic modifications. Unlike “regen, wait, repeat,” when you pull on the geometry, the full representation of the model in its updated state is dynamically generated in real time so you can pull until you like what you see, then release it.
Pricing. At $1700 / year, they've priced it so that it's reasonable for this to be just another tool in your toolbox. To unstick a model. Or to simplify your models for FEM. Or to run at design reviews. Or for a design manager to keep on his laptop.
So there you have it. I think this is very cool, and very needed.
What do you think? I'd love to know...
About me: I am actually a big proponent of parametric feature based modeling. Throughout the 1990s I was a pretty strong Pro/E user. I knew most of the tribal secrets of modeling, for instance, I knew to build a few features and then flex the model to make sure the features would update with the changes. I'd make sure there were no tiny surfaces and edges. I'd be smart about references, using common datum planes and axes wherever I could. When I was done, the models were usually very stable and would respond well to the changes I'd planned to make. (But of course, if changes came from left field, or I had to make changes to a model built by someone else, well, that was another story.)
Full Disclosure: I am an independent consultant hired by SpaceClaim to help out with a few projects for a few hours per week.
