Hi,
The Grasshopper Connection Tool with the latest update (build 4027.0) on ARCHICAD 22 now officially supports Rhino 6 on Windows (it should work on macOS as well, but since that is only WIP, it is not officially supported yet).
Unfortunately support for Rhino 6 file type was not implemented in ARCHICAD 22, and can only be done for the next main version (AC23). In the meantime, connecting through GH or saving back to v5 are the only known workarounds.
