Archicad 29.0.1 API Developer Kit Released - but you might not need it

Daniel Kassai — Fri, 31 Oct 2025 12:33:01 GMT

Dear Add-On Developers,

Archicad 29.0.1 has been released, so we took the opportunity to release some minor API changes in a related Devkit.

Check out the New API features in Archicad 29 to see what has changed.

If you are not using the mentioned class in your add-on, then you have nothing to do. Your add-on built with the AC29.3000 DevKit will still work fine with AC29.0.1.

I recommend subscribing to our Releases page so you get instantly notified when a new Devkit is released.

Happy coding!

Daniel

Hi Daniel,

Thanks for the release! The fix for the ResConv crash is very appreciated 🙂

Do you have any information on when to expect fixes for moving railing vertices and for which AC versions?

Kind regards,
