[Gmsh] saving GMSH mesh into a CAD file format like STEP

Hi Louise,

Gmsh operates using .geo files and .msh files. ".geo" are files that contain the definition of geometrical objects and ".msh" are files containing the meshes generated by the program based on a specified geometry. I do not know if any commercial CAD software natively supports .geo or .msh files but I doubt it. There might still by third-party plugins for some CAD software that might do that.

On the other hand, Gmsh can save both geometries and mesh to a variety of output formats. If you are using Gmsh GUI, simply go the menu bar File > Export or hit Ctrl+E. That will open a window in which you can select the output file format (using the "Type" line, under the "File name" line). If you use Gmsh on the command line, use the -format option described in the online documentation here<http://gmsh.info/doc/texinfo/gmsh.html#Command_002dline-options>.

Hope this helped,

Guillaume Dilasser

I know that GMSH can input CAD model files such as STEP format, I want to check if any CAD software can input GMSH meshes? And can GMSH save meshes into a CAD file format such as STEP?

Thanks, Louise
