Thank you very much for your explanation. I had only a vague comprehension of
this concept, & you helped solidify it. (No pun intended!)
Well, 3DWin is *supposed* to be able to take .DAT files & make .IGS files out of
them. http://www.tb-software.com/products_2.html
I haven't yet been able to make a good .IGS file that SolidWorks 2009 has been
able to import. And, when I take a .SLDPRT file, export it as .IGS, & then
import it back into SW, I've lost the individual construction features in the
feature tree, but all of the geometry on the part (faces, lines, vertecies) is
selectable & usable for mates & further edits & such.
Thus, I concluded that 3DWin should be that conversion software that performs
this task. I've got a help request in to the developer, but I haven't heard
back yet.
Thanks,
-Jason

| Oy, why didn't I think of this before!?!?! There's a SolidWorks-supported website where people upload models for public consumption. I put in a search for "lego" & got 309 hits. This will go a long way towards meeting my needs! (URL) (12 years ago, 22-Nov-11, to lugnet.cad)
