Bison v0.9 Beta: Landscape Plugin for Grasshopper + Rhino 6


(Bison) #1

Bison is a landscape architecture plugin for Grasshopper + Rhino 6. It features tools for terrain mesh creation, analysis, editing, and annotation.

It focuses on a continuous workflow from mesh analysis to editing and works to keep components concise and intuitive. The analysis tools include slope and aspect visualization, cut/fill calculations, watershed modeling and more, while the editing components transform the mesh based on curves and points. Bison also includes tools for importing landscape meshes, triangulation, and resampling, as well as components for annotating plans and cutting sections.

It is currently in it’s first beta release. Please visit for a download link and component documentation.

You can install the plugin by following the Grasshopper drop-down menu to File > Special Folders > Components. Save the ghpy file here and it should be loaded automatically.

You will need Rhino 6 to run Bison. If you get an error when the plugin tries to load, check your system for independent installations of IronPython, which may cause a conflict with GH if an older version is installed.


Hi Bison,
I wanted to test your plugin, it looks mighty useful. I was able to put the GHPY file in the Grasshopper components folder. However, upon launching grasshopper, I am getting this error. I don’t have a standalone IronPython installed. I do however have cPython installed in this machine.

Thanks for the report. This was a known issue with some installations, and has been fixed. Downloading the updated version of Bison (at the same address here) should do the trick.
