Open the attached assembly in the cab editor
Select the main cabinet (glass doors and drawers)
take the cabinet into the face frame editor
Highlight one of the drawer openings
Look at the opening size
Not sure why it shows those values. If you just leave the Face Frame editor and then return back in, it will then show correctly. I will pass it over to the programmers and let them examine it. Is this the only cab/assembly you have seen this on?
