This is was a plugin that worked as a 3D object editor within ArchiCAD 9 but was never updated for v.10 – or so we thought. In fact, the original link referred to in an older post – [[gdl toolbox - freeware]] doesn’t work any more. Just when I’ve started to learn GDL, one of the finest tools made for it is no longer usable. Unless you know Hungarian.
