I recently put together an assembly of the Horus Kestrel, downloaded off of GrabCAD. The parts apparently imported with only minor errors, and the import diagnostic tool successfully solved the issues. However, now I cannot create a new part. Whenever I try, it opens a read-only version of the camera mount from the assembly, with the label "Part.prtdot". Restarting SW or the computer does not help. Does anybody know if there's a solution for this other than a full reinstall of SW?
