One of the better commentaries on this topic. Thanks Jeffery
Siemens has claimed to introduce the next breakthrough in 3D CAD with what they are calling “Synchronous Technology”. While I have yet to get my hands on it, all the demos that are out there look reasonable good, as any demo should. The use model looks nice and the graphical interaction and feedback appears to be very nice.
On the contrary though, what Siemens has introduced, was in reality introduced 10 years ago when Hewlett Packard first imbedded the synchronous parametric solver from D-Cube into their product – SolidDesigner. Since then the product was moved out of HP into CoCreate, and is now a PTC product line. The product is now called PTC CoCreate Modeling. The D-Cube solver delivers synchronous solutions to geometrical relationships like dimensional parameters, coplanar faces, concentric faces, tangent faces, parallel faces, perpendicular faces, symmetry and coincidence. This capability allows an explicit – or “history-free” modeling system to apply needed relationships/parameters to 3D points, edges, faces, features, parts and assemblies on a b-rep solid model. The relationships are solved synchronously and simultaneously. It is a mature and robust technology. Certainly not a new breakthrough as described by Siemens.
HP/CoCreate was the first to introduce history-free modeling in 1994 and the first to deploy a synchronous parametric solver in a production history-free 3D CAD system. It is nice to see followers like SpaceClaim and Siemens ST validate what CoCreate has been doing for years. There are many companies out there that have already been taking advantage of the power and flexibility of so called “synchronous technology”, for many years, with their use of CoCreate Modeling.
