Issues with importing CAD Data (step and iges)

I have been trying to figure out an issue with step and iges files in Unreal Datasmith. When I import the CAD data that I exported out of fusion 360 there are holes or missing parts in the model in Unreal.

Does anyone have any advice on how to fix this?

If it is possible you can edit them in unreal to fix some normal issues, but I don’t know how bad the problems are.

Decently bad, I have tested it with several other iges and step files without issue but it happened with two files back to back. I ended up exporting the files as fbx from their original program to fix the issue. Not a perfect solution but it got around the problem.
