//! - guideline composed of edges of the solid, tangents

//!
//! Tools for construction of the Sp
//! by propagation from an edge of solid
//! are provided in the Builder of Fil3d.
//!
//! The Spine contains among others the
//! information about the nature of extremities
//! of the fillet ( on free border , on section or closed ).
//!
//! IMPORTANT NOTE  :    the guideline
//! represented in this way is not C2, although the path
//! claims it. Several palliative workarounds
//! (see the methods at the end) are planned,
//! but they are not enough. It is necessary to change
//! the approach and double the Spine of line C2 with
//! the known consequences for management of
//! interactions between KPart Blend in Fil3d.
