Thank you all for your help so far. I have learned quite a bit and have completed my mass model for option A of the remodel. I am going to attempt to use building options for my B scheme. I would like to copy some items (for example the front porch flat roof) for building option 2 to building option 3, then edit it to a sloped roof. The best I can figure is to copy the items I want to a new drawing, reset the building option for the items, then copy it back to the original drawing. Is there a better way eliminating the new drawing step?
Thanks again,
Dave
