Hi all,
I had some problems to generate 2D data from a cross section of a 3D
geometry in SolidWorks. Thanks to a note from Rich Bayless, I have
solved this problem: If you know how to do it, it is possible to export
the cross section as a 2D STEP (or IGS) file which gmsh can read. Since
I may not be the only one for whom this is useful, I want to share the
information with the list. You can find it below.

Hello Matthias,
your question about extracting a cross section from
solidworks was interesting. Seems that once you create a 2D drawing
from a solidworks section view, that DWGeditor only allows saving the 2D
entities as DXF, which is not currently supported in gmsh.
I experimented a bit and was able to do what you want,
from within solidworks. Open the 2D drawing with your desired section
view using solidworks. Solidworks will show it as a drawing, not a
part. Open a second window with a new, blank, part. Select all desired
entities, and copy/paste the entities to the new part. The new part
will show a sketch with your entities. Select the sketch and Insert,
Surface, Planar, and it will make a surface. You can then save the
surface as either igs or step, and it will open in gmsh.
I suspect that the above tactics will be useful for
anyone using a commercial 3D cad program.
Hope this helps, Rich.
