OpenSCAD is a script-based 3D modeling software that allows you to create parametric designs using a programming language. Here’s a basic cheat sheet to help you get started with OpenSCAD:
Basic Commands
Cube:
cube([width, length, height]);
Sphere:
sphere(radius);
Cylinder:
cylinder(h = height, r = radius, $fn = resolution);
Polyhedron:
polyhedron(points = [...], faces = [...]);
Transformations
Translate:
translate([x, y, z]) {
// your object here
}
Rotate:
rotate([x_angle, y_angle, z_angle]) {
// your object here
}
Scale:
scale([x, y, z]) {
// your object here
}
Boolean Operations
Union:
union() {
// multiple objects here
}
Difference:
difference() {
// multiple objects here
}
Intersection:
intersection() {
// multiple objects here
}
2D Operations
Linear Extrusion:
linear_extrude(height, center = false) {
// 2D shape here
}
Rotate Extrusion:
rotate_extrude(angle, $fn = resolution) {
// 2D shape here
}

Module Definition:
module myObject() {
// your object here
}
Module Instance:
myObject();
