Looking Nice.

If that means they have some ideas to improve at least there radius tools... that would be great!!

hum ... looks awfully close to FreeCAD on some aspects, doesn't it ? LGPL ?

looks close because it IS FreeCAD: it uses the Sketcher's PlaneGCS solver. But the license in ~/src/Mod/Sketcher/App/planegcs/Constraints.cpp is GPL (not LGPL !)

How can GPL-ed code end-up in a closed proprietary software ?

You can also note that they themselves use OCC 7.3 and not the latest 7.4 ! Don't they trust their own latest code ? Or do they wait for FreeCAD to solve all the bugs ?

It states

GNU Library General Public License

in the quote you posted, so LGPL. Which it should be, as freecad does not use any GPL sources in its bsae code. And with LGPL you are allowed to use it in closed source.

ah yes, you're right, I read too fast. So that's what this means.

In the overview of CAD Builder it states:

Have a look at a free sample of CAD Builder for evaluation. Download an installation Wizard for a standalone Windows application.

So, is this just a version that expires after some time?

[Quaoar]

Just to avoid some misunderstanding in this regard (though, I am not a developer of CAD Builder). The very essence of this tool is to substitute the old Geom module in Salome. It's not going to compete with FreeCAD, and OCC devs are very grateful for this opportunity to grab a piece of FreeCAD's code for a sketcher. Initially, there was also an idea to develop some in-house constraint solver, but this was not justified because of the significant efforts required for its implementation. Another option was SolveSpace but its license was not that permissive.

CAD Builder is a simplified version of Salome.
Salome is opersource software, download page below.
