have used it on occasion when there is an enquiry about a property we have for sale coming in from inter-state (what is it with mexicans wanting floor plans)
attached is a recent one i did...works well enough for what it is - main problem is it doesn't allow guesstimates...it will put a size value (m2) on every room - which is good unless you don't know the dimensions and like the attachement it was all a guess
cheers
