Oh well, it seems like both of the free ANSYS and the free NX software are removing the ability to export much of anything useful outside of their platforms.
If you want to put the NX .prt file inside a .rar file format and attach it to your reply, maybe someone has a full version of NX and can export a Parasolid for you.
Also put the .STL file in a .rar file and attach that too, because SpaceClaim can definitely import that, but there is a tremendous loss if quality in the process.
