Create a Point in Rhino

import Rhino
import rhinoscriptsyntax as rs
pt = rs.AddPoint(10, 20, 30)

Creates a point at specified coordinates in Rhino via Grasshopper scripting.

Let’s Try →

Create Multiple Points in Loop

points = []
for i in range(5):
    points.append(rs.AddPoint(i*10, 0, 0))

Generates multiple points along the X-axis.

Let’s Try →

Draw a Line Between Two Points

pt1 = rs.AddPoint(0,0,0)
pt2 = rs.AddPoint(10,10,0)
line = rs.AddLine(pt1, pt2)

Creates a line connecting two points.

Let’s Try →

Draw a Circle

center = rs.AddPoint(0,0,0)
circle = rs.AddCircle(center, 5)

Creates a circle with a given center and radius.

Let’s Try →

Draw a Rectangle

corner1 = rs.AddPoint(0,0,0)
corner2 = rs.AddPoint(10,5,0)
rect = rs.AddRectangle(rs.WorldXYPlane(), 10, 5)

Draws a rectangle using corner points.

Let’s Try →

Move an Object

obj = rs.AddSphere(rs.AddPoint(0,0,0), 5)
vec = rs.VectorCreate([10,0,0],[0,0,0])
rs.MoveObject(obj, vec)

Translates an object along a vector.

Let’s Try →

Rotate an Object

obj = rs.AddBox([[0,0,0],[10,0,0],[10,5,0],[0,5,0],[0,0,10],[10,0,10],[10,5,10],[0,5,10]])
center = rs.AddPoint(0,0,0)
rs.RotateObject(obj, center, 45)

Rotates an object around a point by a given angle.

Let’s Try →

Scale an Object

obj = rs.AddSphere(rs.AddPoint(0,0,0), 5)
base = rs.AddPoint(0,0,0)
rs.ScaleObject(obj, base, [2,2,2])

Scales an object relative to a base point.

Let’s Try →

Create a Loft Between Curves

curve1 = rs.AddCircle(rs.AddPoint(0,0,0),5)
curve2 = rs.AddCircle(rs.AddPoint(0,0,10),3)
loft = rs.AddLoftSrf([curve1, curve2])[0]

Creates a loft surface between multiple curves.

Frequently Asked Questions about Rhino-grasshopper-scripting

What is Rhino-grasshopper-scripting?

What are the primary use cases for Rhino-grasshopper-scripting?

Parametric architectural modeling. Automated repetitive design tasks. Generative and algorithmic design. Digital fabrication workflows (CNC, 3D printing). Custom plugins or tools for design teams

What are the strengths of Rhino-grasshopper-scripting?

Highly flexible parametric modeling. Visual programming reduces coding barrier. Seamless integration with Rhino geometry engine. Supports complex generative and algorithmic designs. Strong community and plugin ecosystem

What are the limitations of Rhino-grasshopper-scripting?

Steep learning curve for scripting and data trees. Not suitable for large-scale computation without optimization. Grasshopper scripts can become complex and hard to debug. Single-threaded execution in many cases. Dependent on Rhino runtime environment

How can I practice Rhino-grasshopper-scripting typing speed?

CodeSpeedTest offers 9+ real Rhino-grasshopper-scripting code examples for typing practice. You can measure your WPM, track accuracy, and improve your coding speed with guided exercises.
