I was going through an interference check for th first time since we upgraded to 2009, and I got a TON of interferences between light fixtures and ceilings.
Through a little investigation, it seems that Revit is including the light source definition (the yellow piece in the family) as a solid when checking for interference. Obviously this is not a real object and shouldn't be checked for interference, so is this a known issue? Is there a way around it?
Thanks,
Steve
