Is it possible to have discontinuous equality constraints? In other words, I want to have two offices of equal size on either side of another office of undetermined size. For sake of discussion, let's say that the middle office is 12' wide and the building is 36'. If I were to stretch the building to 40', I want to keep the middle office at 12' and have the increased dimension equally divided between each office on either side.
Perhaps it can be done by dimensioning the exterior wall of the flanking offices to the center of the 12' middle office, but this solution doesn't really solve the bigger problem. Similar dimensioning is typical for larger office layouts where that method would not work.
