I have tried all of your suggestions including selecting those options when creating anew drawing. and the default still always reverts to ft-inch. I am a single seat, stand alone user so I am the administrator but I don't know how to get into the administrator variable standards. Can you help with that?Try changing the Drafting standard to ANSI or ASME. Use File + Page Setup. There might be a setting in Tools + Options also.
At most companies, the CATIA Administrator customizes a Standard accordilng to their drafting practices.
