## Definition

template<class Polyhedron, class IGT>
struct CGAL::Polyhedral_mesh_domain_3< Polyhedron, IGT >::Do_intersect_surface

Returns `true` if the element `type` intersects properly any of the surface patches describing either the domain boundary or some subdomain boundary.

`Type` is either `Segment_3`, `Ray_3` or `Line_3`. Parameter index is set to the index of the intersected surface patch if `true` is returned and to the default `Surface_patch_index` value otherwise.
