Yeah, I did this ... but I guess I wanted to know how one can show "dotted lines" when something is "new" and easily calculate the "new" square footage as well. Thanks for the reply though!
I am just getting started ... but I am trying to create a few options for knocking down a back wall and building an addition ... so I want to be able to flip through a few with my wife to show her our current house and a few options.
Any thoughts?
