It seems that the old trick with objects above the cut plane (in my case ceiling mounted light and electrical fixtures), i.e., drawing a model line of the type "invisible" from ceiling to floor no longer triggers Revit to think it is cutting through the family.
This is the case with any family I create in 7.0. My 6.1 and earlier files don't appear to exhibit the same behavior unless I upgrade them.
Anyone else experience this? Fixes?
Thanks
