Does anyone know why I'm getting "Syntax error: Fractions must be entered in 1/32 increments" when I try to specify a depth for the mortise/tenon in face frame construction parameters.
This looks like a glitch. You can go into Face Frame Construction Parameters. Make no changes at all click ok and still get the error.
If you change over to inches and decimal in settings/preferences it will work like it should. After you made your changes you can switch back to inches and fractions.
