Primitive Cylinder

Status: Implemented

Primitive Cylinder creates an exact analytic right cylinder aligned to the +Y axis, with its base at y = 0 and its top at y = height.

Walkthrough

Inputs

• id (string, default null) – names the solid and its faces.
• radius (number, default 5) – taken as a magnitude, so a negative value behaves as positive. Must not be zero.
• height (number, default 10) – distance along the axis. Directional: a negative height builds the cylinder on the −Y side instead. Must not be zero.
• transform (transform, default position [0, 0, 0], rotation [0, 0, 0], scale [1, 1, 1]) – placement baked into the solid before the boolean; the face names are kept.
• boolean (boolean_operation, default operation NONE with no targets and mergeCoplanarFaces: true) – optional union / subtract / intersect after creation.

Behaviour

• Three faces are produced and named from the feature id: {id}_S (side), {id}_B (bottom, at y = 0) and {id}_T (top, at y = height). The solid itself is named {id}.
• A negative height spins the cylinder a half turn about X onto the −Y side; _B and _T keep their identities.
• The feature is never offered by the selection context bar — it takes no references.
