Topic Title

I have modified and resaved some of the door symbols to sizes different from an those in the Datacad Symbol library. When I try to use them the unit height shows as being 2' too tall and the side jambs are 2' too long.
What am I doing wrong. I'm trying to get some 8' interior doors and some 2'4" and 2'0" x 6'8" interior doors.

TIA,
