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.
