Polygon on lateral surface
You can find the reference diameter XR with the "select reference
plane" function (siehe Seite 425).
ICP generates:
 The LATERAL_C section code with the reference diameter
parameter. In nested contours, ICP generates only one section
code.
 A G308 with the parameters contour name and milling depth.
 A G317 with the parameters of the figure.
 A G309.
