Function face_carrier_dimensions_native 

pub fn face_carrier_dimensions_native(
    handle: u32,
    face_name: &str,
) -> Result<Option<CarrierDimensions>, String>

The carrier dimensions of a resident solid’s named face, for the Info panel: a cylinder’s radius and diameter, a cone’s half-angle, a sphere’s radius, a torus’s radii (see crate::surface_carrier_dimensions). Ok(None) for a plane or a free-form face; errs if no face carries face_name.
