I was making some shallow slots for some holes to fit into, and I extruded rather that cut. I found out after I had sketched the holes on the extruded face. I deleted the face, and turned the slots sketch into a cut instead. Next, I had to put my holes sketch on the new cut face, instead of the extruded face that no longer exists. The problem now is SW saw there's dangly bits, but I can't find any more bits that are dangling. I fixed several already, but can't find any more to fix. Last resort CNTRL + Q didn't help either. I'd like to be able to fix these little things, rather than rip up and redo. The holes cut nicely too with the error.
