When I start to draw a room, first I create the shape of It and then change the measure of the wall (click on the dimension and type the number that I want).
So far the first dimension that appears at first It's the outside dimension wall (not the inside of the room). I don't know If is there any way to work with the interior directly instead of click on "auto dimensions" and then start to modify their value.
I'm working as Interior designer, so what I want is the inside of the room, not create the architecture of the building (were the outside dimension is Important).

Thank you for your help
