I am new to Archicad API, but from what I have understood, an element category (door, window, lamp, ...) has parameters (coming from its GDL library object), attributes and properties.
I would like to show all these different things in a tree view (for user selection), the same as the one we can see in the Override rule creation (please see enclosure).
Are there any simple way to do it ? Can someone put me in the right direction ?
Thanks a lot for your help.
