Hole in YZ plane
This hole defines a single hole that can contain the following elements:
 Centering
 Core hole
 Countersink
 Thread
You can find the reference diameter XR with the "select reference
plane" function (siehe Seite 425).
ICP generates:
 The LATERAL_Y section code with the parameters reference
diameter and spindle angle. The section code is omitted for nested
contours.
 A G308 with the parameters contour name and hole depth (–1*BT).
 A G380 with the parameters of the hole.
 A G309.
