python 3d apps

came across some interesting 3d applications in python free-cad is a multi-platform 3d cad program with extensive use of python. not only does it have an embedded interpreter, all the pieces are python modules that can be imported to an external python. even the qt interface can be modified/controlled from python. these guys really did it right. uses opencascade (with pythonocc), coin/inventor, pivy. it claims some nastran support, but the mesh module seems to be entirely geared toward visualizing exterior triangle surface meshes and not for analysis. more fem support is on the dev roadmap. mgltools looks like a very powerful viz tool similar to the old dx. seems to be geared toward molecular stuff, though.
