Thanks for the comment @storiesoferne!
-I didn't like the fact that during the construction they changed the places of the living room and the dining room. It seemed easier for them because of the installations (cable, etc) and now the dining room is bigger than the living room and has a better view. The customers didn't even notice until I asked the contractor.
-I used SketchUp for this project. @desro/fountain HomeByMe is very simple, but I can't add a dwg file and I draw everything in AutoCAD. Even 3d. I like when the dimensions are accurate to the mm, and there is nothing better than Autocad for that.
