Oh no, that geometry is terrible. Imports never work well, though one day AI might just import things with perfect topology, but it seems we’re long was off still. You can select meshes by hovering your mouse on top of a piece and then L on your keyboard to select linked. Then P and separate by selection. I guess what we’re all trying to do is to get you to stick with Blender for the process since it would be much more efficient.
