I've been generating IDF and PTC for Solidworks import from Allegro but plates/non-plated holes are not importing. I have tried version 2.0 and 3.0, with/without filters.
If I open the emn or ldf in text editor, I can see them defined:
MEC_HOLE0320CU0800_CL6 MEC_HOLE0320CU0800 PH7
55.0000 194.2000 0.0000 0.000 TOP ECAD
--> Could "ECAD" designation versus "PLACED" be an issue? I don't know how that is determined
