I'm trying to make a custom door which I've done many times before in previous versions. I've tried both using lines and shapes and using elevation openings which I've exploded. I'm in System library but SP is not allowing me to draw a box around the custom opening. It keeps defaulting to existing openings and not allowing any changes.
Before I submit a ticket to tech could someone draw a simple opening and see if it is or isn't working in 2018?
Thanks
