I am trying to create a nested window family with 6 different combinations. Now where the family seems to be falling down is if i have a window with a bottom transom every thing is fine but if i try to turn off the visibilty of the bottom transom i get a heep of errors - i dont know if it is because i an trying to control the opening size in the wall at the time or the fact that the transom height now equals zero and that value cant be used in a forumula.
I read on one of the other posts to use an empty family but that dosnet help either.
I have attached the family if someone wants to look over it... i think it is a simple problem but cant seem to find a way around it - also the family is far from finished so there is a few parameters not yet used so please disregard.
Thank for any advice.
