YZ plane: Circular figure pattern
This function defines a circular figure pattern in the YZ plane.
Special cases of starting and end angles (A, W):
„ Without A and W: Figures are arranged on a full circle, starting at 0°
„ Without W: Figures are arranged on a full circle
Parameters
Y
Center of pattern in Cartesian coordinates
Z Center of pattern in Cartesian coordinates
a Center of pattern in polar coordinates (reference angle:
positive Z 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: Z axis)
W End angle, position of the last figure (reference: Z axis)
Wi Angle between two figures (algebraic sign has no effect)
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
maintained (translation)
Description of the figure
When defining patterns with circular slots, the “center of
curvature” is added to the pattern position.
