Archicad 29 and Rhino 8 grasshopper connection issue

Sol4rpunk — Sat, 14 Mar 2026 12:57:47 GMT

Hello hello,

Do you guys know how to make Archicad 29 work with Rhino 8? I can see it on the grasshopper plugins bar but not in the title bar (and so I can’t activate the connection) .. If someone has a clue and managed to make it work… Thank you !

Have a nice day.

It works fine for me with Archicad 29 and Rhino 8.

I usually start Archicad, open the file I want to connect with Grasshopper. Then, I start Rhino, start Grasshopper, and open the Grasshopper file I want to connect with Archicad.

Then, in Archicad, I bring up the Grasshopper palette (File > Interoperability > Grasshopper Connection menu commands), and click the Start button under "Sync Changes to GH".

Then, in Grasshopper, I bring up the Archicad Connection Palette (Archicad > Archicad Connection Palette menu command), and click the Start Connection button.

This normally establishes the connection between the two apps.
