I've got a building model that won't show the roof slab when you change the visual style while looking at the plan view. Everything seems fine in an Iso view, its just the plan view that I'm have the problem with. I've tried to redraw the slab as well as copied the info into a new drawing, neither solution worked. I have possibly determined the cause: The display representation of the roof slab is set to "plan" where other models I've looked at show "model". Problem is that it's grayed out so I can not change it. Maybe this is a solution, maybe not.
Any thoughts or ideas?
