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