I have been using this product for more than ten years and am very satisfied. Lost my original copy so bought another at a great price. I have used this for professional remodel designs and preliminary drawings for a new home. This application is very easy to learn, fast, and has some basic 3d capability. My biggest gripe is that it won't print bigger than 8 1/2 x ll inches. But, it is possible to export files to other CAD applications for larger printer format, if you don't mind some fiddling with the imported file. Highly recommended for preliminary design and remodel projects where drawings won't be submitted to your building dept.
