OpenSCAD 3D Modeling

Overview

OpenSCAD is a programmer's solid 3D CAD modeller that uses scripts to generate 3D models. Unlike interactive 3D tools, OpenSCAD models are described declaratively in code, making them ideal for AI-driven generation. Models are built from primitives (cube, sphere, cylinder) combined with boolean operations (union, difference, intersection) and transformed (translate, rotate, scale).

Key Concepts

Constructive Solid Geometry (CSG): Combine simple shapes into complex models using boolean operations

• union() - Combine multiple shapes into one
• difference() - Subtract shapes from each other
• intersection() - Keep only overlapping regions

Primitives: Basic building blocks

• cube(size=[x,y,z]) - Rectangular box
• sphere(r=radius) - Sphere
• cylinder(h=height, r=radius) - Cylinder
• polyhedron(points, faces) - Arbitrary shape
