//! Provides methods to build edges.
//!
//! The methods have the following syntax, where
//! TheCurve is one of Lin2d, Circ2d, ...
//!
//! Create(C : TheCurve)
//!
//! Makes an edge on the whole curve. Add vertices
//! on finite curves.
//!
//! Create(C : TheCurve; p1,p2 : Real)
//!
//! Make an edge on the curve between parameters p1
//! and p2. if p2 < p1 the edge will be REVERSED. If
//! p1 or p2 is infinite the curve will be open in
//! that direction. Vertices are created for finite
//! values of p1 and p2.
//!
//! Create(C : TheCurve; P1, P2 : Pnt2d from gp)
//!
//! Make an edge on the curve between the points P1
//! and P2. The points are projected on the curve
//! and the previous method is used. An error is
//! raised if the points are not on the curve.
//!
//! Create(C : TheCurve; V1, V2 : Vertex from TopoDS)
//!
//! Make an edge on the curve between the vertices
//! V1 and V2. Same as the previous but no vertices
//! are created. If a vertex is Null the curve will
//! be open in this direction.
