Instructions for Installing Ladybug + Honeybee:

Follow initial steps 0-5 for Ladybug functionality and additional 6-9 for full functionality.


  1. If you have an old version of LB+HB, download the file here and open it in Grasshopper to remove your old Ladybug and Honeybee version.

  2. Make sure that you have a working copy of both Rhino and Grasshopper installed. Rhino 6 comes with Grasshopper pre-installed but, for Rhino 5, you will have to install Grasshopper from here

  3. Open Rhino and type "Grasshopper" into the command line (without quotations).

  4. If using Rhino 6, skip this step and continue to step 4. If using Rhino 5, install GHPython by downloading the file here and drag the .gha file onto the Grasshopper canvas.

  5. Select and drag all of the userObject files (downloaded with this instructions file) onto your Grasshopper canvas. You should see Ladybug and Honeybee appear as tabs on the grasshopper tool bar. If you are reading this instruction on github you can download the LB+HB components by following this link

  6. Restart Rhino and Grasshopper. You now have a fully-functioning Ladybug. For Honeybee, continue to the following:
