I believe that sub-levels should work similarly to the levels in terms of constraints. Throughout my testing, the sub-level change of elevation does not affect the top of the wall - and the wall-height.
I understand that the constraints rely on the height value of each level, when the sub-levels do not have such value. IMO sub-levels should affect geometry of va objects with constraints - like the walls. Please add those to previous wishes-suggestions about the level manager and the elevations of sub-levels relative to their corresponding levels.
The sub-levels elevation can be displayed relative to the Building Elevation or to the Global elevation, but not relative to the Host level. We can change this behavior and show it relative to the Level when the Toggle level’s elevation is activated.
