During evaluating different design options the highest point of the roof ended up higher than the initial roof level line. If I try to move the level line to the top of the roof, the whole roof moves with it. Is it possible to disassociate (temporarily) a roof level line from the roof itself in order to move it to the top of the roof and then associate it with the roof again.
I would like to avoid creating a new level line (at the correct elevation) and delete the old, in which case the roof is no longer associated with the new level line.
