+At first it is necessary to define the reference coordinate system, where the sketch will be created:
- The XOY plane of the <b>Global coordinate system</b> is suggested by default (if no plane or planar face is selected when <b>2D Sketcher</b> is activated).
- If any Local Coordinate Systems have been created in the study earlier, they can be selected as a reference coordinate system in the corresponding list box.
- The \b Arrow button allows selecting a \b plane or a <b>planar face</b> in the viewer or in the object browser as the reference coordinate system for the sketch. The start point will be set in the \b geometric \b center of the face.
- <b>Restore</b> button orientates the viewer correspondingly to the chosen working plane and fits the scene to show all objects.
-\n It is possible to create sketches of two types:
+It is possible to create sketches of two types:
- \b Profiles made of <b>line segments</b> and \b arcs, or
- \b Rectangles.
<h2>Creation of a Profile by straight segments</h2>
- Choose \b segment radio button to start a \b profile.
+
- Define the start point. By default the start point of the curve is located at the origin of the reference coordinate system. A point in 2D Sketcher can be defined in one of three ways:
- - By \b Absolute coordinates. Select \b Absolute radio button in \b Points group, input \b X and \b Y values and click \b Apply button.

- - By \b Relative coordinates. Select \b Relative radio button in \b Points group, input \b DX and \b DY values and click \b Apply button.

-\n Alternatively to the definition by \b Points it is possible to define segments by \b Direction and \Distance.
+Alternatively to the definition by \b Points it is possible to define segments by \b Direction and \b Distance.
- The \b Direction can be:
- - Defined by an \b Angle to the previous segment.

- - \b Perpendicular to the previous segment (i.e. the Angle is 90 degrees).

- Use \b Undo and \b Redo buttons to cancel an erroneously applied segment or to restore it.
<h2>TUI Commands</h2>
-\n <em>geompy.MakeSketcherOnPlane(Command, WorkingPlane)</em>
+<em>geompy.MakeSketcherOnPlane(Command, WorkingPlane)</em>
This algorithm creates a sketcher (wire or face), following the textual description, passed through the <i>Command</i> argument. The edges of the resulting wire or face will be arcs of circles and/or linear segments.
- \em Command is a string, defining the sketcher by the coordinates of points in the current LCS.
- <em>WorkingPlane</em> can be a Local CS, a plane, or a planar face.
-\n Another way to create the 2D Sketcher in TUI is using Sketcher2D interface.
