Thank you all for your help, but I have given up on building options for now. I had my mass model looking good for both my A and B options, and started adjusting for finishes, and I messed up both models with errors I can't correct. I have saved it out as two separate projects and am trying to put it back together, but for future reference (and my next attempt) I have a few questions:
1. I had a option A wall with windows in it. Option A was sided, option B was a stone veneer. When I changed the windows to option B, then deleted the wall on option A, the windows are also deleted. It is like they stayed attached to the wall they were in, even though they were on different options. Is that correct?
2. My roofs got all messed up. It seems as though if any "lollipop" is attached to a different option wall or beam I could not get it to appear on the render. Do all it's supports need to be on the same option?
3. Some other roofs seem to extend to different walls or roof lines when brought from one option to another?
Thanks,
Dave
