The origin of some of my groups is on the wrong level. For example, I have a few balconies in a group because the pattern of balconies is the same on each level. The group on Level 18 says Reference Level = Level 18, but the Origin Level Offset = -5600mm (2 floors less the railing height). I don't know why it is this way.
Is there a way to raise the origin up within the group and keep all the groups where they are placed?
