-The dialog is opened from \ref managing_dimensions_page "Manage Dimensions" dialog when "Add" button is clicked.
-This dialog allows creating measurement dimension for the selected geometrical object.
-The following types of dimensions can be constructed:
-<ul>
-<li>Length.</li>
-<li>Diameter.</li>
-<li>Angle.</li>
-</ul>
-
-Being constructed, the dimension is positioned by application such that the user is able to see it from the most appropriate angle of view.
-The application selects one of the best matching planes allowed for the dimension. If extending the dimension by increasing length of flyouts
-make sense, then the application extends the flyouts for a default value specified on the \ref geometry_preferences_page "geometry preference dialog".
-
-Once constructed, the geometrical properties of dimension preview (flyout, plane) become interactively editable in OCC viewer.
-For the description of interactive operations please refer to corresponding section at \ref managing_dimensions_page "Manage Dimensions" page.
-
-The legnth dimension can be constructed in three ways: as length on edge, as length between two points and as length between two parallel lines.
-In order to construct the dimension, the selected geometry should met the following conditions:
-<ul>
-<li>Edge length - only the line edges are accepted. E.g. constructed from line segment, on two points.</li>
-<li>Two points - any two points.</li>
-<li>Parallel edges - only the parallel line edges are accepted.</li>
-</ul>
-
-The diameter dimension can be constructed for the following geometry types:
-<ul>
-<li>Arc and circle. The selected geometry should be an arc, a circular edge or a circular face.</li>
-<li>Sphere, cylinder, cone, torus.</li>
-</ul>
-
-The angle dimension can be constructed in two ways: as angle between two edges, as angle by three points.
-The following conditions should be met:
-<ul>
-<li>Two edges. The edges should be located in same plane.
-<li>Three points. Any three points, with the second point being the center of the angle.
-</ul>

+- 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:
+- \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.
+	
+	\image html 2dsketch1.png	
+
+	- 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.

+	- By \b Selection of an existing point. Select \b Selection radio button in \b Points group, select a point in the viewer or in the object browser and click \b Apply button.
+	
+	\image html 2dsketch3.png
+
+- Define the next point. Together these two points form the first segment of the sketch.
+
+\n Alternatively to the definition by \b Points it is possible to define segments by \b Direction and \Distance.  
+ 
+- The \b Direction can be:
+ 	- Defined by an \b Angle to the previous segment.
+
+	\image html 2dsketch4.png
+	
+	- \b Perpendicular to the previous segment (i.e. the Angle is 90 degrees).
+	
+	\image html 2dsketch5.png
+		
+	- \b Tangent (collinear) to the previous segment (i.e. the Angle is 0 degrees).
+
+	\image html 2dsketch6.png
+	
+	- Defined by <b>VX-VY</b> vector coordinates.   
+	
+	\image html 2dsketch7.png
+	
+- The \b Distance can be defined: 
+	- By the absolute segment \b Length or 
+	- By \b DX - the length of segment projection on X-axis. 
+	- By \b DY - the length of segment projection on Y-axis. 
+	
+- Proceed with creation of the sketch segments and click \b Apply after each step. The drawn segments will be displayed in the viewer. 
+- Use \b Undo and \b Redo buttons to cancel an erroneously applied segment or to restore it. 
+- To finalize, click <b>"Close"</b> button to apply the created wire "as is". 
+- Alternatively, click <b>"Sketch Closure"</b> to close the Sketch by a straight line
+from the last created segment to the start point and apply it.
+
+<h2>Creation of a Profile by ark segments </h2>
+
+If an \b ark radio button is chosen, \b Point or \b Direction define the location of the next point of the sketch, but this point and the previous one are connected by an ark segment. 
+
+\image html 2dsketch10.png "Ark segments"
+	
+- By default, <b>None (Tangential)</b> radio button is selected as <b>Additional Parameter</b>,  and the arc is \b tangential to the end of the sketch, which means that it is created on two points as a half-circle with radius equal to a half of the distance between these points.
+
+\image html 2dsketch12.png

+- \b Radius radio-button allows creating a more limited arc segment by defining a custom  ark radius, which must be greater than half of the distance between the last point and the end point of the arc.

+\image html 2dsketch8.png
+
+- Finally, \b Center radio-button allows explicitly defining the center of the circle. If an arc segment cannot be built on the defined points, a warning is shown.
