I see what you mean. Yes, dumb 2D objects such as fills and lines do not have many properties. In Revit some types of these objects can have some useful properties associated with them. But even more powerful is Revit's "detail family" system where you can simply draw any 2D thing and classify it. You can then use these detail families anywhere where you can place/draw 2D elements. The advantages are numerous:
- these are no longer dumb objects
- you can draw them yourself and even make them parametric
- you can build up a library of commonly used 2D elements, which have been fully classified/annotated and simply place them where you need them
It would be great if ArchiCAD had a similar feature. Like you say, not everything has to be 3D all the time.
By the way, you might want to consider changing the title of this post/wish to something like "Add ability to classify 2D objects" or something more descriptive.
