Here are a few images to illustrate the issue:
The intention is to be able to stop the top of gyp board below the top of wall framing, as is common in commercial interiors. I have approached this by placing an offset modifier to control the height of the gyp board independent of the overall wall height.
The problem is that when the wall height is made taller or shorter than the height as drawn in the profile manager then the gyp board moves away from the bottom of the wall. Truly bizarre behavior. Eliminating the value of the parameter altogether...
If I try to fix the bottom of the gyp to the point of origin by using an additional offset modifier I run into 2 problems. First, because the profile manager does not allow more than one offset modifier attached to an edge I can only create one on one of the 2 finish sides of the wall. Second, I still get very strange behavior when I zero out this 'base reveal' modifier to try and get the gyp to extend to the floor. Archicad actually lifts the bottom of the wall core above the point of origin to achieve the offset of zero, rather than pulling the gyp board down to the point of origin. WTF?!?!?!
There really NEEDS to be a way to anchor multiple points or edges to the stretch extents (or other guidelines) AND allow edges to be locked to each other, AND place more than one offset modifier on an edge.
Otherwise offset modifiers are of very limited use.
