Dear Sirs, I really thank you for your help. The suggestion of saving in STEP from FreeCAD fixed my problem. So far my geometries are simple and I am only interested in mesh the resulting surface. Thanks to your hints I have gotten what I need. Btw, thanks for the remark about non-conformal meshes.
