Primitives#

Primitive constructors return a Shape object centered at the origin (Z-up).

• box
• cylinder
• cone
• sphere
• torus
• rounded_box
• chamfer_box
• hole_chamfer

box#

box(w, d, h) — Rectangular box centered at origin.

const result = box(40, 30, 10);

cylinder#

cylinder(r, h, segs=32) — Cylinder centered at origin, axis along Z.

const result = cylinder(10, 30);         // r=10, h=30
const result = cylinder(10, 30, 64);     // smoother

cone#

cone(r, h, segs=32) — Cone with base radius r, tip at top, centered at origin.

const result = cone(8, 20);

sphere#

sphere(r, segs=32) — Sphere centered at origin.

const result = sphere(15);
const result = sphere(15, 64);   // smoother

torus#

torus(innerR, outerR) — Donut shape in the XY plane, centered at origin.

const result = torus(5, 15);   // tube radius 5, ring radius 15

rounded_box#

rounded_box(w, d, h, r) — Box with rounded vertical edges.

const result = rounded_box(40, 30, 10, 3);   // 3mm radius

chamfer_box#

chamfer_box(w, d, h, c) — Box with chamfered (45°) vertical edges.

const result = chamfer_box(40, 30, 10, 2);   // 2mm chamfer

hole_chamfer#

hole_chamfer(r, h, c) — Cylindrical hole tool with a chamfered entry, ready to subtract from a box.

const base = box(40, 40, 10);
const hole = hole_chamfer(4, 10, 1.5);   // r=4, h=10, chamfer=1.5mm
const result = base.sub(hole);
