\r
98 segment and arc. The
\r
99 curve is created from the current point (center of coordinates when the
\r
100 sketcher is started). The
\r
101 end of the curve is defined by means of "destination", which
\r
102 can be a destination point (for segment only) or destination direction
\r
103 coupled with length of a segment or angle and radius of an arc.</p>
\r
107 <p>Sketcher is able to create planar curves only. Therefore, it is necessary
\r
108 to select a working plane before starting a sketch (by default, XOY plane
\r
109 is used). Sketcher creates curves lying in the current working plane (New
