|
|
segment and arc. The
|
|
curve is created from the current point (center of coordinates when the
|
|
sketcher is started). The
|
|
end of the curve is defined by means of "destination", which
|
|
can be a destination point (for segment only) or destination direction
|
|
coupled with length of a segment or angle and radius of an arc.</p>
|
|
|
|
<p> </p>
|
|
|
|
<p>Sketcher is able to create planar curves only. Therefore, it is necessary
|
|
to select a working plane before starting a sketch (by default, XOY plane
|
|
is used). Sketcher creates curves lying in the current working plane (New
|
|
Entity -> Basic -> Working Plane).</p>
