Using the same part in SOLIDWORKS 2016 & 2017, someone here noticed that the shortcuts in the flyout menu have changed.
2016 on the left, 2017 on the right
It is a sheet metal part with references within an assembly.
Open the part and right-click a face.
Hitting the letter "X" used to get "Export to DXF / DWG" in 2016, it now gets "List External Refs..."
Yeah, my co-workers find ALL of the odd little changes . . . I don't suppose there is a way to change it back without hacking the registry?
