pub fn body_crossing(
params: &ValidationParameters,
model: &Model,
bodies: &[Body],
) -> GeopResult<Option<(EdgeId, FaceId, Vector3)>>Expand description
An edge of the bodies bodies that crosses the trimmed region of one
of their faces away from every vertex, with where: a body running into
itself or into another. None if no edge does — which does not rule
out two faces crossing along a curve no edge of either reaches.
