This would be great, we would just need a simple way to disassociate the elements when as needed. My other concern is what happens to performance as we start adding more inter-element relationships to maintain. As I recall this was a serious problem with early versions of Revit and may still be an issue with the later versions.
Also why do we have to differentiate between the 3 type of elements.
Let archicad automatically select the element
I assume this is because they can be laying over one another in plan when using a model oriented layer combination. I for one like being able to be explicit about which type of element I want to drop something on.
and why while we are at it how about a ballon effect of attaching to the underside of an element.
This is an excellent idea! I'm surprised it never occurred to me. It would be a great way to install lights, fans, crown mouldings and all sorts of things.
