I might as well tack my inquiries to this thread as I am about to try to do what mgianzero is/was doing a few months ago. I'm about to remodel a kitchen and adjoining utility (laundry) room/garage access. Some months ago I tape-measured and created a SU model of the utility room, but only of it's inside-facing surfaces (walls without thickness) and the project went no further. Now I've found our house plans and I'm thinking (as mgian--Marc did) that raising the house from those would be easier than measuring it out manually.
So Gaieus has suggested to import a raster file (.tif? .jpg? .gif?) and to scale it. Is there a video or tutorial for that? Does it come in as a lot of pieces of a group that you stretch together to a hand-entered length? My experience with SU is limited--I have one previous thread here, where I was creating an underground geological "landscape". You folks were great help to me finishing that project. Sadly, I have not had the time or need to do anything else with SU until now.
