/*! \page create_wplane_page Working Plane Definition of a <b>Working Plane</b> is necessary for work with \ref create_sketcher_page "Sketcher". \n To create a <b>Working Plane</b> in the <b>Main Menu</b> select <b>New Entity - > Basic - > Working Plane</b> \n There is a number of algorithms to set the <b>Working Plane</b> and the Camera Position. \n Firstly, you can select a \b Plane, a <b>Planar Face</b> or a <b>Local Coordinate System</b> to be your <b>Working Plane</b>. \n <b>Arguments:</b> Name + 1 selection (plane or planar face). \image html workplane4.png \n Secondly, you can define a <b>Working Plane</b> by two <b>Vectors</b>. \n <b>Arguments:</b> Name + 2 vectors. \image html workplane5.png \n Finally, you can select one of three basic projections of XYZ coordinate system to be your <b>Working Plane</b>. \image html workplane6.png <b>Reverse the plane normal</b> checkbox allows changing the direction of the working plane. <b>Example:</b> Working plane on the upper face of a box. \image html image36.gif <center>Normal Direction</center> \image html image47.gif <center>Reversed Direction</center> */
