+The case when the edges that form the wire have different tangency in
+the connection points (sharp bend) is not processed.
+
+<b>TUI Command:</b> <em>geompy.MakeEdgeWire(Wire, LinearTolerance, AngularTolerance)</em><br>
+<b>Arguments:</b> Name + 1 wire + Linear Tolerance + Angular Tolerance
+(tolerance values are used to check coincidence of the underlying curves).

+Thirdly, it is possible to build an edge of required \b Length on any existing
+\b Edge.
+
+<b>Start Point</b> parameter is optional:
+- if used, it allows selecting any existing point - in such a case the start point
+of the new edge will be chosen as start or end point of the selected \b Edge
+whatever is closest to the selected <b>Start Point</b>
+- if it is missed, the start point of the initial edge is used
+
+<b>Length</b> can exceed the length of the initial edge length or be
+negative. In this case the existing edge is extrapolated
+along its curve (except for bezier and b-spline curves).
+
+<b>TUI Command:</b> <em>geompy.MakeEdgeOnCurveByLength(Edge, Length, StartPoint = None)</em><br>
+<b>Arguments:</b> Name + 1 edge + Length + 1 Vertex
