Mustafa,
Thanks for another vallant attempt!
Unfortunately, I've hit a bit of a bump in the road implementing your solution.
When it comes to the routine placing connectors on the face that I want. I get a null exception at this line
CachedDoc.ActiveView.SketchPlane = sp;
I can't quite seem to get it to work correctly at all. In the interest of a more direct example of what I'm wanting this to do. I've attached a few things. First, I've attached a code sample of where my code is at on this matter. If you test this code, BE SURE to use the .rfa file I've attached. This particular instance corresponds to this particular Mech. Equip item. I've also attached a screenshot showing exactly which face this particular routine will attempt to place a connector onto.
Thanks!
