Steps for updating add-on to work with Archicad 21

Anonymous
Not applicable
Hello,

I have a working add-on, developed and working on Archicad 20. When I try to add it in Archicad 21 I get the "outdated" error in the add-on manager. What are the steps to migrate to the newer API?

Thanks in advance,
Julian

You need to rebuild the add-on against the AC21 API rather than AC20. This will probably entail some code changes – just like ARCHICAD, the API grows and develops over time. How many changes depends on which parts you're using.
