I am planning to purchase a good design software program to help with various projects. I am considering Better Homes & Gardens Home Designer 7.0 or BH&G Interior Designer. I not building a home but designing rooms and may or may not move walls but am most interested in creating the floorplans, 3-D views and also placing furniture and or built-in units in the designs. Does Home Designer 7.0 do all of this or would the Interior Designer program work better for me? Thanks.
