* flat (2D) geometry. The Z direction has always to be 0.
* The position and orientation of the Plane this 2D geometry is
* referenced is defined by the Placement property. It also
* has a link to a supporting Face which defines the position
* in space where it is located. If the support is changed the
* static method positionBySupport() is used to calculate a
* new position for the Part2DObject.
* This object can be used stand alone or for constraint
* geometry as its descend Sketcher::SketchObject .
