Both. Essentially I'm looking to partition an 1,100 square ft area - design the room layout and the interior. Potentially including electrical circuits and AV systems, although not essential.
Ideally I would like to be able to export floorpans, possibly annotated, that would save me having to redo them in another program.
I'm going to have a look at Sketchup but wondering if there are any better programs for this.
