What it can do
- Models massing, floor plates, cores, facades and vaults, and produces plans, sections and gross and net area schedules.
- Checks what the geometry means as well as whether it is valid, with assertions on bounding boxes, counts, watertightness and support, returning the offending object IDs.
- Offers lean, standard and full tool profiles and three access modes (safe, standard, developer) set through an environment variable.
- Ships a rhino-architect Agent Skill that sets out phase order, millimetre defaults and verification cadence.
Limitations
- Windows only; the installer is a batch file that configures every AI client it finds.
- The Rhino plugin has to be installed once through PlugInManager before the bridge starts with Rhino.
Install
Download or clone the repository, close Rhino and your AI client, run INSTALL.bat, then in Rhino 8 run PlugInManager once and install RhinoAIBridge.rhp from %APPDATA%\McNeel\Rhinoceros\8.0\Plug-ins\RhinoAIBridge\. Restart your AI client and ask it to "ping Rhino".{
