Function make_cone 

pub fn make_cone(
    model: &mut Model,
    frame: Frame,
    base_radius: f64,
    top_radius: f64,
    height: f64,
    tol: Tolerances,
) -> OgeomResult<Built>

Build a cone or a truncated cone in frame.

base_radius is at the frame’s origin and top_radius at height along its z. A zero top radius makes a true cone, whose apex is a degenerate edge and which has no top cap.

Errors

OgeomError::Construction if the height is not positive, a radius is negative, both radii are zero, or the two radii are equal; that last is a cylinder, which is a different surface with its own type, and admitting it here would ask for a cone whose apex is at infinity.
