CAD-Modell ist loaded in a wrong way

Post by ozi »

Hello,
when I try to load a CAD-Modell I always get a problem with round objects, they are all hexagonal. I tried several different format like STL, DXF, DWG, etc. The only format which is running well ist OBJ

does anyone know this problem?

This is due to tesselation (all the mesh formats are triangular ones and the CAD software needs to convert the parametric surfaces to a set of triangles.

Generally you have some options regarding the tesselation density / precision in your CAD software.

Thanks for your quick response

If I understand you correct, I have to check the parameters of the software which is creating the CAD-Model. The smaller the triangles are, the rounder the objects will be, correct?

Thx

Yes. Generally it's more a parameter related to the number of triangles, but I guess a smaller size will work as well.
