I use in intermittently, works OK. Better I think than when it was first introduced. I have not had the rotated problem. In honesty I use it mostly for organic shapes so I don’t often use the generated wall geometry feature, and my use is often “close enough”. Here is a real world scan with the model.
I only use it to take a quick note of the space. I have yet to have any success with getting it to be more useful than “oh… there’s an outlet there…”
Sometimes the mesh is rotated, sometimes the actual building geometry is, I usually just take my own measurements and model from those and double check the mesh when I need to know why there weren’t cabinets on one wall (electrical panel) or some such similar
Here’s a floor plan with two versions superimposed: One generated by Scan to Design for the entire floor, and one done the manual way by measuring and modeling. Doing a single room at a time is a little better.
