1.15 TURN PLUS: XY Plane Contours

XY plane: Circular figure pattern

This function defines a circular figure pattern in the XY 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

X Center of pattern in Cartesian coordinates (radius)

Y Center of pattern in Cartesian coordinates

a Center of pattern in polar coordinates (reference angle:

positive X 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: X axis)

W End angle, position of the last figure (reference: X 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.
