I am looking for software which would allow me to design a home and present it to potential architects. I need something which a novice could use just to decide the exterior, landscape, and floor plans. Maybe quite possibly also do a layout of the rooms. I would like something fairly simple, but if simple isn't the way to go then that is fine. Whatever software you feel is best, if you could direct me to a place to get a very good tutorial that would be great! Thanks for all help.
