Grasshopper Internal Node Example

[Number Slider] -> [Multiply (×2)] -> [Circle (radius input)]

A simple Grasshopper workflow using internal nodes: Number Slider -> Multiply -> Circle. This creates a circle with a radius controlled by the slider.

Let’s Try →

Python Script Component Example

import Rhino.Geometry as rg

pts = []
for i in range(10):
    pts.append(rg.Point3d(i*2.0, 0, 0))

# 'a' is the Grasshopper output parameter
a = pts

Custom Python node in Grasshopper that creates a series of points along the X-axis.
