Hello, i was hoping someone can help me out. I am looking for a program for my computer where i can draw out a floor plan and build interior walls and when im done, i can do a 3D walk though of the interior and exterior, and it shows everything in detail from where the coffee table is to what colour the walls will be. i know, many programs on the net do this, i am just wondering what is the best one. and if someone could recomend one that offers a trail period that would be helpful because i only need it for one project, thankyou.
