Salut Marc, et merci pour ta reponse.
I visited your website and read your tips about using SolidWorks.
I undestand what you mean now for the primitive detection, making
the objects in CAD using polygons instead of circles. That makes
things a bit more complicated than I had hoped.
Also I read that you need to do some manual work in the .DAT file
after creating it with your utility. Is this a lot of work? I
am completely unfamiliar with internal details of .DAT files.
I'm wondering if it would be productive to the CAD community if
I could help by modelling parts in CAD (Pro/ENGINEER) and creating
the .DAT file, but then hand that .DAT file to someone else
who can "finish it", someone who is experienced with .DATs.
Would this be of any help? I don't yet fully understand how
it's decided who works on which parts, and how they are "approved"
into the official libraries.
Merci,
KDJ
