I am a new user of the ArchiCAD 16 Software. I want to know whether is it possible to customize the new style of Railing in stairs with Parametric Control. If yes, Please let me know the Steps to archive it.
Multiple posting about the same topic in the wrong subforum is not the way to get what you seek.
May I suggest that you put all this together in a single topic in the Libraries/Library Parts/GDL forum. Please be clear about exactly what it is you are looking to do.
