pub fn free_bounds(model: &Model, shape: &Shape) -> OgeomResult<FreeBounds>Expand description
The free bounds of shape: every edge only one of its faces walks, a
degenerate edge aside, chained head to tail into contours. See the
module documentation.
At a vertex where more than one free edge carries on, the one the same wire walks next is taken first, so a face’s own rim comes out whole.
§Errors
OgeomError::Dangling if a handle
fails to resolve.
