after taking my floor plan and making it a 3d model, is there an easy way to get back to the original floor plan? i know about the parallel and the perspective views, but that still leaves the walls. i want to get back to where there is no height to it at all. the original 2d floor plan.
Go to a side view, select all except the floor and delete.
You should have the floor plan left. Some touches up might be required.
It would help if you post your model here so someone can take a look and check that what I describe is feasible or not.
The method I use is to create a horizontal section. You usually want the plan to show window and door openings and if you only shows what happens at ground level, they may not show up.
