\n <b>TUI Command:</b> <em>geompy.MakeVertexOnCurve(Edge,Parameter).</em>
\n <b>Arguments:</b> Name + 1 edge + 1 Parameter defining the
position of the point on the given edge.

-\n Fourthly, we can define a point by intersection of two \b Lines.
-\n <b>TUI Command:</b> <em>geompy.MakePointOnLinesIntersection(myLine1,myLine2).</em>
-\n <b>Arguments:</b> Name + 2 lines
+Alternatively, it is possible to define a point by an \b Edge and a \b Length.
+The \b Length defines the position of the point on the given edge. It
+can exceed the length of the edge or be negative. In this case the edge
+is extrapolated along its curve (except for bezier and b-spline
+curves).
+The <b>Start Point</b> defines the direction for the length
+calculation (if not defined, the first vertex of
+Edge is used, else the vertex of Edge closest to StartPoint is used).
+\n <b>TUI Command:</b> <em>geompy.MakeVertexOnCurveByLength(Edge,Length,StartPoint=None).</em>
+\n <b>Arguments:</b> Name + 1 edge + 1 Length + 1 Point.

+It is also possible to define 3D coordinates of the point
+projected on the given edge to produce the resulting point.
+\n <b>TUI Command:</b> <em>geompy.MakeVertexOnCurveByCoord(Edge,X,Y,Z).</em>
+\n <b>Arguments:</b> Name + 1 edge + 3 coordinate values of the
+projected point.

+\n Fourthly, we can define a point(s) by intersection of two \b Lines or \b Wires (or a Wire and a Line).
+If they intersect only once, a point will be created. If there are several intersections, a compound of
+points will be created. The type of the selected object (Line or Wire) can be changed in the popup menu,
+after clicking the corresponding selection button. (see the picture below)

-\n Finally, we can define a point by a \b Face and two <b> Parameters: U </b> and \b V
+\n Finally, we can define a point by a \b Face and
+Two <b> Parameters: U </b> and \b V
indicating its position on the Face, ranging from 0.0 to 1.0. For example, (0.5; 0.5) means that the
point is located in the middle of the face.
\n <b>TUI Command:</b> <em>geompy.MakeVertexOnSurface(myFace,myUParameter,myVParameter).</em>

+Alternatively, it is possible to define 3D coordinates of the point projected on the given face.
+\n <b>TUI Command:</b> <em>geompy.MakeVertexOnSurfaceByCoord(myFace,X,Y,Z).</em>
+\n <b>Arguments:</b> Name + 1 face + 3 coordinate values
+to project point on the given face.
