You are not wrong Eric! I am embarrassed to admit the whole situation, which had me held up for days, was simply a matter of views. You see I had grown accustom to using "doll house view" to look at my interior space, which at least in my case, was truncating my view of interior walls. The same perspective, viewed in "Full Camera" reveals that my walls were, in fact, complete all along. See attached image.
Sorry to have bothered you with such a dumb mistake. Then again, had you not showed me walls worked for you, who knows how long I would have been stuck.
Don't be surprised if you hear from me again, next time I am stumped. Until then, thanks for getting me back on track.
