Release History

Note, that because of the interface changes significantly release by release, we do not ensure neither interface nor binary compatibility with previous versions.
So add-ons compiled with older DevKits cannot be loaded in the ARCHICAD 25.

The following documents contain detailed information on different aspects of API development.
Please consider these rules and recommendations in order to develop solutions conforming to ARCHICAD.
