I've looked through the archives and I don't find anything current on this topic. I would think that there have been some significant developments here in the last few years. Ideally, I'd like something where you can scan/download photos of the four elevations and the program would figure the dimensions based on standard sizes such as an entry door. Alternatively it may ask you to put in a few known reference points such as the distance between two windows and figure the dimensions from there.
It may also use that information to figure common placement of bearing walls and use that to help locate interior partitions, plumbing and ventilation runs, etc.. These would probably be on some sort of "verify" basis and could really shorten the time to establish the existing structure prior to creating the additions.
For the remodeling or additions it should keep the bearing walls aligned and suggest most efficient plumbing and ventilation setups. It would be nice if it would take an upstairs addition floorplan and suggest various roof/gable/dormer choices.
I'm not at all interested in landscaping choices which seem to be a lot of the "fluff" in the things I've checked out so far, and while the interior and exterior finishes may add a little value, I'm really more interested in the meat and potatoes of the structure and general appearance.
Thanks for any help.
