Trying to manage door, frame and hardware tracking with assets to a single opening. Doors are generally modelled as door and frame. I can group assets by system, but I can not assign a system to an object. I can reference a frame asset to an object, but I can not reference a door asset to that same object. Each component have their own properties, and trade to be assigned to with different status sets. Additional capability would allow for the degree of management our site would need.
