Model "explodes" when imported to Dimension

I'm trying to make renders of a CAD model, so the wireframe isn't super pretty. In Maya, the model looks fine, but when it's imported to Dimension it looks crazy. It's super jagged and I can't seem to figure out what the problem is. I've tried redoing the UVs as well as averaging normals and using "set to face" to see if that helped, but there was no luck. I've attached pictures of the model in Maya and in Dimension. Any thoughts?
