Function shape_profiles 

pub fn shape_profiles(
    name: &str,
    sketch: &Sketch,
    geometry: &Enclosure,
    shape: Shape,
) -> GeopResult<Vec<Profile>>

The profiles of shape, one of the sketch name’s, its points at geometry: each region’s loops, its outer loop first and then its holes, one region after the other — or the one open chain — each named after the sketch and its elements (see chain_of_pieces).
