I've been attempting to import a .stp file provided by a vendor. Typically, after import there are 1 or 2 problematic faces that can usually be healed. However, I then end up with 80+ gaps and I've not found anyway to resolve them. These gaps seem to be associated with tapped holes. I'm not experienced w/ the surface tools and don't fully understand what the problem is. I have blindly tried multiple import options, however the processing time is substantial making iterations painful.
I'd appreciate any guidance the community can offer.
