ours in the YZ plane
Centric polygons in YZ plane
This function defines centric polygons in the YZ plane.
You can switch between edge length (Ki) and width across flats (K) by
pressing a soft key (see table at right).
You can find the reference diameter XR with the "select reference
plane" function (see page 411).
ICP generates:
 The section code SURFACE_Y with the reference diameter and
spindle angle. The section code is omitted for nested contours.
 A G308 with the parameter contour name.
 A G487 with the parameters of the polygon.
 A G309.
Soft key
Switches the field to entering the
width across flats K.
Reference data of the polygon
ID
Contour name
C Spindle angle (position angle of the surface normal)
XR Reference diameter
Parameters of the polygon
Z
Reference edge
Q Number of sides (Q>=2)
K Width across flats
Ki Length of side
B Width (reference: reference dimension ZR)
 B<0: Surface in negative Z direction
 B>0: Surface in positive Z direction
