Issues importing CAD

Hello,

I am currently experiencing quite a few issues when it comes to importing our CAD models for a particular part that we are running. The main issue is that when the part is imported, there are a lot of artifacts all over the model, surfaces are inside out, we're unable to select some portions of the part to do our measurements on, and there are planes added on that don't show up in NX.

Is there some settings that we could adjust to fix this possibly? We are importing them in as .stp and we've tried .iges as well. Is it possible to do straight from NX as a .prt?

Thank you,
Kaleb
