EW - Edge wedge
EW r,q1,qc(,qd)[;]
r ; Radius in user units or graphics units
qc ; Arc angle
 Plots a wedge centred on the current position with radius r, start point angle q1, arc angle qc and chord angle
qd.
 After plotting, the cursor returns to its point of origin.
 Plotting is performed whether the pen is up or down.
 When scaling has been performed, the circle is plotted in user units.
 Also, when scaling has been performed, the value for r is a real number.
 When there is no scaling, the circle is plotted in graphics units.
 When there is no scaling, the coordinate value for r is an integer number.
 The value for q1 is a clamped real number.
q1 specifies the wedge starting point related to the 0 degree reference point.

When q1 is positive, the positive direction of the X axis relative to the current position is set at 0 degrees and

the start point is sought in the counterclockwise direction. The opposite occurs when q1 is negative: the
negative X axis is set at 0 degrees and the start point is sought by going clockwise.
qc specifies the angle of the wedge in degrees.

The value for qc is a real number.

Plotting proceeds counterclockwise when qc is positive and clockwise when negative.

The value for qd is a clamped real number.

 When qd is not specified, the chord angle is the default value ( 5 degrees )
