Detailed Description

Contains information necessary for construction of a 3D fillet or chamfer:

guideline composed of edges of the solid, tangents between them, and borders by faces tangents between them.

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.
