color=#0000ff size=2>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.</FONT></SPAN></DIV>

<DIV>Hello Matthias,</DIV>
<DIV> </DIV>
<DIV>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.</DIV>
<DIV> </DIV>
<DIV>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.</DIV>
<DIV> </DIV>
<DIV>I suspect that the above tactics will be useful for anyone using a
commercial 3D cad program.</DIV>
<DIV> </DIV>
<DIV>Hope this helps,
Rich.</DIV><!-- END WEBMAIL STATIONERY --></BLOCKQUOTE></BLOCKQUOTE><!-- END WEBMAIL STATIONERY --><p><font size="2" face="Arial">
