CI - Circle Plot
CI r(, qd)[;]
r : Radius of circle ( in user units or graphic units )
qd : Chord angle ( in degrees )
• Plots a circle centred on the current position with a radius r and chord angle qd.
• After plotting, the cursor returns to its point of origin at the centre of the circle.
• 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 scaling is off, the circle is plotted in graphics units.
• When there is no scaling, the coordinate value for r is an integer number.
• When qd is not specified, the chord angle is the default value (5 degrees).
