Before, when clicking the side arrow next to the "Import" button in Part Design, a drop down menu would appear, with an option to "Import CATIA File", but after the recent hotfix that button no longer appears for me. In fact, the whole drop down menu doesn't. The "Import" button itself does not give the option to import CATPART files. Is there any way to fix this?
