Ok, thank you so much. But if I assign a label to an archiCad element, I can read almost all the information I need from that element, for example If I assign a label to a wall. I can have the width of the wall, height of the wall.
If i create a 2d object, I can't have all of this kind of information.
I can't have link between a column and a 2d object, if that make sense to you.
Sincerely,
Daniel
