Greetings-
I have a sheet metal assembly with threaded inserts and some slots, when I create the detail drawing of this assembly, it will not allow me to place centermaks on PEM inserts or slot, just centerlines on the side view . However if I create a detail drawing on the part file I have no issue. Any clues?
Make sure the part is oriented straight on in the assembly.
If there is even a hint of an angle the holes and slots will be elliptical and SW hates that for centermarks.
