ShapeAnalysis_Edge Class Reference

Tool for analyzing the edge.
Queries geometrical representations of the edge (3d curve, pcurve
on the given face or surface) and topological sub-shapes (bounding
vertices).
Provides methods for analyzing geometry and topology consistency
(3d and pcurve(s) consistency, their adjacency to the vertices).

(second one)
toler1 returns necessary tolerance for first vertex,
toler2 returns necessary tolerance for last vertex.

edges is overlapped.
theDomainDis - length of part of edges on wich edges is overlapped.
