Constraints between objects & elements.

[Cosminn]

Hello everyone, it's there any chance to have constraints between archicad elements (beam, column, roof, wall, etc.) & gsm. objects? For example, if there is a beam, and i want that one parameter from my 3D gsm object, to be always constrained by the beam height. Thanks

Not via GDL other than zones. GDL objects have no awareness of any other model elements (including other objects) other than the zone(s) in which they exist.

Add-ons (plug-ins) created with the ArchiCAD API (programmed in C/C++) can associate objects with another element. That is what is done, for example, by the Accessories 'goodie' which associates wall or roof claddings with walls or roofs: the cladding is adjusted as the associated wall or roof is adjusted, and accomodates any doors, windows or skylights.
