ours in the YZ plane
Hole in YZ plane
This hole defines a single hole that can contain the following elements:
 Centering
 Core hole
 Countersink
 Threads
You can find the reference diameter XR with the "select reference
plane" function (see page 402).
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 parameters contour name and milling depth
(-1*BT).
 A G380 with the parameters of the figure.
 A G309.
