When will the Archicad 28 sync version come? You are very late.
The last plugin for Archicad was released in January 2024. So we would only have something in two months. Or in the worst case scenario only in version 3.0 of D5. 
Hello @danielpaes @Daniele89
It is complete and currently undergoing internal testing. Thank you for your patience. Any updates will be provided.
