This function defines a circular hole or figure pattern on the front/rear
face.
Parameters
XK
Center of pattern in Cartesian coordinates
YK
Center of pattern in Cartesian coordinates
a
Center of pattern in polar coordinates (reference angle:
positive XK axis)
PM
Center of pattern in polar coordinates
Q
Number of figures
Orientation:
Clockwise
Counterclockwise
R
Radius of the pattern
K
Diameter of the pattern
A
Starting angle, position of the first figure (reference: XK axis)
If A and W are not programmed: Figures are arranged on a
full circle, starting at 0°
W
End angle, position of the last figure (reference: XK axis)
If W is not programmed: Figures are arranged on a full circle,
starting at A
Wi

Position of the figures
Normal position: The original figure is rotated about the
center of the pattern (rotation)
Original position: The position of the original figure is
