by length). This operation is available in <b>OCC Viewer</b> only.
\n The \b Result will be a \b GEOM_Object.
\n <b>TUI Command:</b> <em>geompy.DivideEdge(Shape, EdgeID, Value,
IsByParameter), </em> where \em Shape is a shape which contains an edge to
be divided, \em EdgeID is the ID of the edge to be divided, if it = -1,
then Shape is an edge, \em Value is a paramter on the edge or a
length. \em IsByParameter if it is True then Value is the edge parameter
in the range [0:1] otherwise it is a part of the length of the edge in the range
[0: full length of the edge]

- \em Shape is a shape which contains an edge to be divided
- \em EdgeID is the ID of the edge to be divided, if it is = -1,
then \em Shape should be an edge itself
- \em Value is a value of parameter on edge or length parameter,
depending on \em IsByParameter.
- \em IsByParameter is a boolean flag, specifying operation mode:
- \c True: \em Value is treated as a curve parameter [0..1]
- \c False: \em Value is treated as a length parameter [0..1]
<b>Arguments:</b> Name + 1 Edge + 1 Value setting the position of
the point according to one of the selected modes.
The difference between "by parameter" and "by length" modes becomes
apparent on the edges with irregular parametrization (for example,
b-splines which usually have irregular density by the length).
For example, value 0.5 "by length" on such edge will produce the point
in the middle of this edge (equidistant from both its ends); the same
0.5 value "by parameter" will result in the point situated closer to
one of the ends (depending on the actual parametrization).
