OK, David and Solver. That's bad news. I've moved from a similarly priced product that had great function in this area (like all competing software, there are pluses and minuses) so I may have to go back to that older product until I get a final design, then come back to HD.
I may be wrong but users of a product like this will often be doing what I'm doing, trying to put together a new design that works for us and that means discarding many and putting together new ones. At a minimum the width of walls is an important factor (especially for me, as I have a limited footprint to work within) that can affect room layout. I'm not as bothered about the materials. It would be nice if I could at least select multiple walls and update common properties (I can also do that with that other product, by the way, though I can also define new walls) but I haven't found a way to do that, either.
Don't mind me, just getting a bit tired of defining individual wall properties, so I thought I'd try to figure out how to avoid it. I could upgrade to Pro but I'm not sure I'd get $250 worth of extra value there.
Thanks for responding.
