Hello,

Take a look at www.opencascade.org. This is a powerfull C++ library
for building CAE
(Computer Aided Engineering) applications. It also has a rather steep
learning curve,
but the resulting geometry could be easily exported to FEA packages.

Another possibility is www.salome-platform.org which is build on top
of OpenCascade. It has
a nice Python interface which makes the learning curve probably a
little more acceptable. A
downside is that, I think there are no Windows binaries yet.

Regards,
