At the beginning of my relation with ArchiCAD after listening to the sales pitch of the GS salesman I have asked this question:
Jus for long this library parts will remain compatible with the program.
The answer was : As long as there will be ArchiCAD. I called GS and was reassured of this as a fact,
And this is the way it was version after version. Since many of us modified library parts and the new version just whipped them out we had a common wish; Name the folder with the version number.
Using this as a subterfuge GS started to name each object with the version number and through “agents” let us understand that there area compatibility/speed problems with the old ones. This is inadmissible and counterproductive to the dream of GDL being embraced by the industry,
