Create mesh in NX3

[matteorivelli]

In the CAD environment of NX3 i have created a cube and after with the operation of subtract i have created a sfere in the center of cube, after i have went in the FEM environment then i have created a scenario and a 3D mesh but i have noted that the mesh recognize only the cube and not the cube with a sfere hole in the center, how i can resolve this problem?
thanks.

I'm not familiar with your particular problem, but from a manufacturing side in UG I know it doesn't handle spheres well at all. The fight is on when trying to get the software not to violate the geometry.

I can't figure out where the edit post box is...

But the problem seems to be realated to how parasolids recognize shapes without clean tangents relative to the work. I've had solid bodies like you refer to become hollow bodies in the past. It won't do well on triangular type shapes either like with .stl either. Back in my Unix days it would produce a core explosion (little fire cracker eating all your system resources until deleted.)
