Primitive Cone

Status: Implemented

Primitive Cone builds an exact analytic cone or frustum 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.
• radiusTop (number, default 5) – radius at the top. 0 creates a sharp tip.
• radiusBottom (number, default 10) – radius at the base. Must not be zero.
• height (number, default 10) – distance along the axis from base to top. Directional: a negative height builds the cone 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.
• boolean (boolean_operation, default operation NONE with no targets and mergeCoplanarFaces: true) – optional union / subtract / intersect after creation.

Behaviour

• Both radii are taken as magnitudes.
• Faces are named {id}_S (side) and {id}_B (bottom), plus {id}_T (top) when a top cap exists. A top radius of 1e-7 or less builds an apex cone, so there is no _T face even though radiusTop is not exactly zero.
• A negative height spins the cone onto the −Y side; the face names are kept.
• The feature is never offered by the selection context bar — it takes no references.
