Hey folks, Completely new to Chief Architect products but was talking into buying Interiors by a couple people who have used these products. My goal right now is just to design a finished basement. Currently the basement is just poured concrete walls, and i'm not finishing all of it. I have the dimensions of the areas I want to finish, so I'm curious how to go forward in the software, specifically in terms of the walls. I don't care about exterior walls or any exterior dimensions because of the scope of the project. All I have are interior dimensions. So should I start with exterior walls anyway and then plug in interior walls to get the best results for usable interior space and measurements?
