Add material

Turn a profile into a solid, or grow one along a path.

A revolved knob. Draw half the section as a closed path, then spin it. finish() names the material; the color option tints the anodised surface.

const section = path()
  .moveTo(4, 0)
  .lineTo(16, 0)
  .lineTo(16, 6)
  .lineTo(9, 22)
  .lineTo(4, 22)
  .close();

return section.revolve().finish('anodized', { color: '#2F6F63' });

JavaScript is off — the listing above is the whole example.

Calls

Call	What it does
`Sketch.extrude(depth) => Shape`	Extrude this closed sketch normal to its plane by `depth` (mm).
`Sketch.revolve() => Shape`	Revolve 360 degrees around the Z axis.
`Sketch.sweep(rail, opts?: { frenet?, transitionMode?, spine? }) => Shape`	Sweep this profile along a 3D rail.
`Sketch.loft(other: Sketch \| Sketch[], opts?: { spacing?, planes?, ruled?, startPoint?, endPoint? }) => Shape`	Loft this profile through one or more additional sections to produce a 3D solid that smoothly interpolates between them.
`variableSweep(spine: Curve3D \| Sketch \| Vec3[], sections: Array<{ t: number; profile: Sketch }>, opts?: { closed?: boolean; continuity?: "C0" \| "C1" \| "C2" }) => Shape`	Multi-section sweep that blends `sections[i].profile` along the spine at the section's `t ∈ [0, 1]` spine parameter.
`helix({ radius, pitch, turns, axis?, pointsPerTurn?, startAngle? }) => [number, number, number][]`	Polyline helix rail for `Sketch.sweep`.
