There are two interfaces for Pollination in Rhino. You can use the Pollination panel to use buttons to create your analytical model, or you can type Pollination commands in the command line.
Pollination Panel
To pull up the Pollination panel, type Pollination in the command line. Once you hit Enter, the Pollination panel will emerge. You can dock it in your window as you would a native Rhino panel.
Pollination Commands
A list of Pollination Commands for Rhino with detailed descriptions is available in this user manual. You can also type "PO_" in the command line to preview a list of commands in Rhino.
