3D Sketcher allows creating a closed or unclosed 3D wire from a list of points.
To create a 3D Sketch, select in the main menu New Entity -> 3D Sketch.

In this dialog it is possible to define the coordinates of the points.
The position of each point can be defined by \b Absolute coordinates X, Y, Z or
by \b Relative coordinates DX, DY, DZ with respect to the previous Applied point.
The type of coordinates can be selected by the Coordinates Type
radio buttons.
To add the point in the list of points and to proceed with the
definition of the next point, click Apply button. \b Undo and
\b Redo buttons, respectively, remove or restore the last point in the list.
\n "Sketch Validation" button applies the wire, built by the
user, "as is".
\n "Sketch Closure" closes the Sketch by a straight line from
the start to the end point and applies it.
To make a closed wire using the TUI command, the first and the last point should
have the same coordinates.
The Result of the operation will be a \b GEOM_Object.
TUI Command: geompy.Make3DSketcher( [ PointsList ] )
This algorithm creates a wire from the list of real values, which define XYZ
coordinates of points.
