Very old projects

Going forward this should be less of an issue, but if you have a really old project, all the old libraries have been downloaded for your use:
S:\05 Project Resources\05.100 Archicad Support\05.101 Archicad Libraries

AC17 - SU will be integrated (...one less add-on) and what is the future of GDL?

Sketchup will be integrated

But a not so promising future for GDL after all the years of promises?
