Hi Michael,
thank you for your fast answer. The "generate high quality n-gon meshes isntead of only triangle meshes.." sounds good,
because often triangle polygons bring problems. In moi3d you can edit how much polyons / quality of the mesh you need?

I tried the v3 version before for a short time, but the trial version is ended before i could test it much.

If i buy the v3 now, get i the v4 in the next months?

best regards

Orhan
