I understand that you can do inside and outside dimensions manually. What I'm really after is chief architect automatically showing the inside dimension when I click on the number to edit the wall length. For example, I draw a 9' wall horizontally then a 9' wall vertically. CA defaults these as outside dimensions so I would need to set it at 9' 4.5" to get what I want (9'). If I want to change the wall length to 6'...I need to type in 6' 4.5".
Is there a way to set CA to work exclusively with inside dimensions where my 9' is 9'? Also, drawing a wall 6' 4 3/8" and adding 4 1/2" for the wall leaves room for error/confusion.
