Why can't I union these parts, despite them overlapping significantly?

There are no artifacts visible or anything, like, visually this looks super clean, the parts clearly stick into each other with most of their bodies.

It looks like you're trying to work with mesh parts. While it is possible to perform operations on them, they are very very picky. Is there a good reason you're using imported meshes instead of modeling the features?

I tried doing this before with a complicated imported doodad I wanted to attach to my object to save sketch time (If I could even do it) I couldn't get it to work in OnShape so I fired up 3D Builder and stuck the two parts together like Play-Doh and Voila! had it 3D printing 5 minutes later.

There has to be a way for imported objects to be sketch copied with OnShape without having to manually do it..?

I took a modell of a skull somewhere, which I couldn't produce on my own. I wanted to fill in some gaps, and hollow out nose and eyes, to make it look more real. I finally got it to work, but yes, meshes seem tricky. Always have to have that bit of extra overlap.
