It would be great to build the system with more dependencies between construction elements. Currently there is only few dependencies - windows and doors depend on the wall, roof light on the roof, curtain wall elements - on the overall geometry of curtain wall and labels linked to the elements. By another hand windows and doors became too complicated by amount of details and parameters: now window contains geometry of window itself, plus sill, plus board, plus masonry arch... When for example masonry arch or lintel isn't window - it depends on window position and size, but it is separate element, that built separately on different stage of construction. I imagine with the new dependencies engine can be solved problem with accessories from Goodies, timber roof structure from RoofMaker can be connected to roof geometry, floor joists to slabs, studs to walls, balustrades to stairs and similar.
