I'm wondering how others properly draw a basement remodel plan to accurately show the plan and 3D model view. In my first attempt, I drew the existing foundation walls and left a space, then drew a new interior wall where it would be added. I know this isn't the best method because it creates a "room" between the foundation wall and new interior wall. However, it seemed to work in terms of making the plan view look correct for permit drawings. My struggle with this method is when I tried to accurately show windows (in 3D model), I could not get the window to cut through both walls. So in my next attempt, I created a new wall type with a concrete wall, air space, then interior wall. This worked for the windows, but the new wall type did not properly connect (in plan view) to other interior walls and to the concerete foundation walls that remain in the unfinished areas. See attached picture. Any suggestions?
