This ranks among the worst software that I have ever used. I have Professional Home Design Suite Platinum version 10. You set the elevation for each floor, the program changes it to something else. Walls appear in the 3-D renderings and can't be erased. The keyboard shortcuts don't work. You apply shingles to the 3-d elevations, and the program renders the windows with shingles. You try to get tech support answers to the above issues and you can't even get past the first tech support screen. Hello...Is anybody home?
