Sorry if the title is an incorrect description for what i am trying to do.
But i am trying to remove these holes in the model, however this is a very complex model and has waaaay to many polygons. I think this is because it was modeled in solid works. I did not generate this model but i would like to modify it. Any tips would be greatly appreciated!!
I would think reducing the polygons would be step 1 but the mesh is triangulated. I did not have much luck with using alt+j on this, i am newer to blender and do not know all of the tools yet.
Here are the pictures:
