-3D Sketcher allows creating a closed or unclosed 3D wire from a list of points.
+3D Sketcher allows creating a closed or unclosed 3D wire, made of
+consequent straight segments.

-The position of each coordinates can be defined by absolute coordinates X, Y, Z or
-by relative coordinates DX, DY, DZ with respect to the previous Applied point.
-Type of coordinates can be selected by the <b>Coordinates Type</b> radio buttons.
-\n <b>"Sketch Validation"</b> button applies the wire, only red part will be built by "Sketch Validation".
-\n <b>"Sketch Closure"</b> will close the Sketch by straight line from last red part and apply it. 
-To make a closed wire using the TUI command, the first and the last point shoul 
-have the same coordinates.
+The first sketcher point can be defined by \b Absolute coordinates X, Y and Z.
+When the first point is defined, it is possible to add straight segments.
+Each segment will start at the end point of previous segment or at the
+sketcher first point, if there are no validated segments.
 
-The Result of the operation will be a \b GEOM_Object.
+Segment can be defined by:
+ - \b Absolute coordinates X, Y and Z of its second end,
+ - \b Relative coordinates DX, DY and DZ of its second end with
+   respect to the previous applied point,
+ - \b Direction and \b Length of the segment. Direction is set by two
+   \b Angles in selected coordinate system.
 
-<b>TUI Command:</b> <em>geompy.Make3DSketcher( [ PointsList ] )</em>
-This algorithm creates a wire, from the list of real values which define XYZ 
-coordinates of points.
+The way of segment construction can be selected by the <b>Coordinates Type</b>
+radio buttons.
+
+To validate the segment and to proceed with the definition of the next
+segment, click <b>Apply</b> button. \b Undo and \b Redo buttons,
+respectively, remove or restore the last segment in the wire.
+
+\n <b>"Sketch Validation"</b> button applies the wire, built by the
+user, "as is".
+\n <b>"Sketch Closure"</b> closes the Sketch by a straight line from
+the start to the end point and applies it. 
 
 <b>Example:</b>
 
 \image html 3dsketch1.png
 
+<b>TUI Command:</b> <em>geompy.Make3DSketcher( [ PointsList ] )</em>
+This algorithm creates a wire from the list of real values, which
+define absolute XYZ coordinates of points. The Result of the operation
+will be a \b GEOM_Object.
+
+\note To make a closed wire using this TUI command, the first and the
+last point should have the same coordinates.
+
+\n Another way to create the 3D Sketcher in TUI is using Sketcher3D
+interface.
+<b>TUI Command:</b> <em>sk = geompy.Sketcher3D()</em>
+Returns an instance of Sketcher3D interface <i>sk</i>.
+Use the below examples and see the \ref gsketcher.Sketcher3D "Sketcher3D"
+interface documentation for more information.
+
 Our <b>TUI Scripts</b> provide you with useful examples of the use of
 \ref tui_3dsketcher_page "3D Sketcher".
