In order to get going let’s start with a simple example (see “HelloKaramba3D.gh” in the examples archive): Place a C# scripting component on the canvas, right-click on its icon and select “Manage Assemblies . . . ” from the context menu. In order to make the “karambaCommon.dll” and “karamba.gha” assemblies accessible to your script, click on “Add” left beside “Referenced Assemblies” and browse to the files. They both live in the “Plug-ins”-folder of Rhino (e.g. “C:\ProgramFiles\Rhino6\Plug-ins”). From there all users can access the Karamba3D plug-in. By default one only sees “.dll”-files. Select “Grasshopper Assemblies (*.gha)” from the drop-down list on the lower right side of the browse-window.
