    Try It

    1. Download Rhino 8 Evaluation for Windows or Mac.

    In Rhino

    1. Type ScriptEditor in the command prompt to open Script Editor. The Editor begins initializing Python 3 runtime (this only happens after a fresh install and can take a few moments to complete).
    2. When ready, click the New button and create a new Python 3 or C# script from Examples.
    3. Click the Run (play) button to execute the script.
    4. Explore other examples to see how you can use third-party packages in your scripts.

    In Grasshopper

    1. Type Grasshopper in the command prompt to open Grasshopper. The Editor begins initializing Python 3 runtime (this only happens after a fresh install and can take a few moments to complete).
    2. When ready, from the Maths panel, add a new Script component to the canvas.
    3. On the script component, click on a language to start a new editor with a default script.
    4. Add a few inputs and outputs to the component. Pass data to the inputs.
    5. Now click the Solve button in Grasshopper.
    6. Open the Examples panel in Editor to explore other Grasshopper script examples.
    7. Use the Templates panel to initialize your new scripts.
