Why there is no forward version of GDL Development Kit?

Archein — Wed, 24 Dec 2025 10:28:48 GMT

Hello everyone,

I'm trying to create a GDL authorization function.

However, the newest version of the GDL DevKit is 23.

Does it possible to create a forward version from GDL DevKit 23?

Hi Archein,

Unfortunately it's no longer possible to create GDL extensions for versions newer than AC23.

There was some statement by Graphisoft if I remember correctly.

In case you want to authorize GDL objects to specified Archicad Keys or Archicad users, you can check the requests here under "Configuration_number" and "GSID_INFO".

Or what do you mean with "authorization function"?

Best regards,
Bernd
