Guys I thank you for the help. I and wanting to design a venue like a concert hall that would have a sloped floor for the audience. I have played around with p.solids and created ramp with a wider width at the top and a narrower width at the bottom, was not too easy for me. I already designed the facility without the sloped floor and now I need to figure out how to put one in without starting over. I should get it right in about a year, lol
