Having used TurboCAD over the years for mostly 2D residential permitting/construction drawings, I take an intersest in threads such as these you have started. Having been a framing-contractor and general-contractor for the past many years (as well as a residential designer/draftsman)- and not at all being a "computer-graphics" guy, I have yet to find much (paying $$) utility for much 3D work in my geographic area (though I do utilize 3D beneficially to illustrate or "figure things out" sometimes).
I've done a lot of the types of 2D residential drawings similar to what you are trying to do/learn.
I can still readily remember learning (via usually late-night or early-morning back-and-forths with the more knowledgeable in this Forum). I would say that- at this point of what you are trying to accomplish, and in your point in the learning-curve- I would suggest going with: a) definitely using the Walls Tool as opposed to double-lines, or the like; and b) using a 0" wall-height (in the 3D properties tab, in my ver. 11) There will be a lot less complications later (like maybe on your future thread with your Openings Blocks not behaving correctly).
(If you want to for the fun of it- after you somewhat finished your basic walls layout- you can select all your walls [Edit|Select By|Entity Type|"Wall"] and assign a height to them [like 10'-1", for example]. Then go to a Standard Isometric View and see what can easily be done- see what they look like (that's really cool the first time). Just "Undo" afterwards.)
Anyway... for now, at the point you are, I would definitely suggest that you stay in 2D drawing, and assign nothing more than a 0" height to anything (the default height- meaning that if you do nothing, everything will be in 2D, with 0 height)
like I said- What you are trying to do and learn is exactly up my alley, so I'm going to be keeping an eye on your posts for a while.
