Thanks a lot.

I tried both in combination and it worked.

Yeah, it worked. Thanks.

But there are still these ugly deformations on the surface. Do you've got an idea how to correct this simply ? Or is it to complex?

Hey,

I've got Maya 8.5 and I've imported a 3D-geometries from ArchiCAD/AutoCAD as DXF/DWG. The whole mesh consists of triangles. Thats not the prob at all. It looks like it is a bit deformed....
