Dave, Thanks for pointing me to Salome. I've played a bit around with it and created a simple 3D geometry consisting of the union of a cube and a sphere: http://www.kuleuven-kortrijk.be/~bartv/cube_and_sphere.hdf I exported this to a STEP file: http://www.kuleuven-kortrijk.be/~bartv/cube_and_sphere.step but when I try to open this STEP file in gmsh with $ gmsh cube_and_sphere.step i get errors: Error : Something wrong in edge loop Warning : OCC STL triangulation failed I'm wondering if the problem is somewhere with my gmsh settings or with the generated .step file. I *think* the problem is with the .step file itself, because when I import it in Salome/Geometry the sphere doesn't look complete. I have however no idea how to solve this. Since it looks to me like a problem with the .step file, I assume it is something I should take care of in Salome? What should I pay attention to in Salome so that the .step files that I generate are easily read by gmsh? Regards, Bart -- "Share what you know.
