Does anybody know how to get the constraint solver? Please refer to the demostrations "http://www.opencascade.org/showroom/demos/".

Currently, what kinds of constraint solvers could be used usually, free or for sale???

I don't know of any that are integrated with OCC, but I think that is the direction the developer of psketcher wishes to go in eventually.

Hi, Mark, Rob, Stephane, thank you so much for your answer.

Is there any open source code for that? Thanks a lot.

Probably the most prevalant commercial geometric constraint solver is produced by D-Cubed, currently owned by Siemens. Check out the fact sheet at:

FYI, a long time ago (around 1996 when I was working at MDTV) I implemented a bridge/connector between D-Cubed 2D and OCC ( Cas.Cade 1.4 at this time ) , and it was working quite good.
