Hi Matthias Have you had a look at MeshLab http://meshlab.sourceforge.net/ which might enable you to do what you want if you export in stl format first? Regards mark

If I get it to work, I will be happy to share it, but I am still struggling at the moment... My problem is that gmsh will not mesh my 'cleaned' geometry. What I try to do is to determine the surfaces and lines which are identical, delete the unnecessary ones and redefine the volumes using the remaining surfaces. I use an external tool (scilab script), so I did not modify gmsh. Please find in the attachment my test geometry in STEP format and the geo file I want to use for the 3D mesh. gmsh does the 2D and 2D meshing without problems, but crashes during the 3D mesh (either I get a net crash, or gmsh does not respond any more after some time, and I have to kill it). Did I do something wrong when generating the geo file? I would be very happy if someone could have a look on my case. I am using gmsh 2.5.1svn under Windoze XP.
