I watched Creo presentation on October 28 and I should say that I was a little bit disappointed with the PTC strategy for the next decade (as they announced it). They are promising to revolutionize CAD market with Creo but what they demonstrated is looked more like evolutionary changes to the existing applications. In any case, it can’t be compared with the real 3D modeling revolution initiated by Parametrics 25 years ago.
What I expected from 3D modeling revolution is, first of all, the long waiting integration of 3D parametric modeling and 3D direct modeling approaches in one powerful and easy-to-use application. What PTC is promising us in Creo is the common data model for Pro/E and CoCreate, but not the common workspace for both parametric and direct modeling. Pro/E and CoCreate remains to be separate applications (only names are to be changed) that can only exchange data with each other. Not too much for New CAD Revolution.
As for 3D parametric modeling itself, it remains more or less the same as it was proposed 25 years ago. All “parametrics” is concentrated mainly in 2D sections (as for me, I would like to see a full freedom of parametric constraints in 3D space) and the capabilities of this 2D solver is rather restricted – it can resolve sections with about 2000 entities and fall down for more complicated sections.
To my mind, the poor solver of Pro/E is the main reason why PTC is not able to implement a real integration of Pro/E with CoCreate (instead of this they explain us that it is much more convenient for users to work with Pro/E and CoCreate as separate applications). Actually, this integration should be the main direction for the New CAD Revolution. In order to provide such an integration one should develop a solver that could work with hundreds of thousands of entities and resolve corresponding systems of equations in real time.
Can we expect to have such a solver in Creo? As far as I understand, Creo doesn’t promise any progress in this direction.
Can we expect any other progress in computational aspects of the parametric approach (for instance, using advantages of multi-core processors)? It seems to me that the answer is “no” again…
I’m rather skeptic about the New CAD Revolution if inside Creo will be the ancient parametric engine that was developed for Pro/Engineer 25 years ago.
