Hi ... I'm trying to build a bonus room above a garage. I don't want to have to use a roof pitch above a 6/12 so I tried to make the garage have 12' ceilings, build the roof, and then build the second story. When i built the second story I lowered the ceiling in the garage to give more height in the bonus room. However when I do this I get an error message when trying to create a roof truss. It tells me it can't be done because "A flat ceiling must be present for the middle of the truss, and floor platforms present for the ends of the truss." How do I convince the program that there is a ceiling and floor platforms?
Thanks!
