This program allows you to design or redesign your existing home or design a new home. Try different wall colors, surface materials, furniture, etc before purchase. Know what your landscape will look like (even 40 years from now). So very many built in materials - and you can import your own if you want. This program is so very adaptable to design or redesign - you can even put your own family heirlooms in the rooms. It's easy to learn. We sat down and learned it in an evening without any previous CAD training.
