ours in the XY plane
Hole in XY plane
This hole defines a single hole that can contain the following elements:
 Centering
 Core hole
 Countersink
 Threads
You can find the reference dimension ZR and the limit diameter IR
with the "select reference plane" function (see page 402).
ICP generates:
 The section code FRONT_Y with the parameters reference
dimension, spindle angle, and limit diameter. The section code is
omitted for nested contours.
 A G308 with the parameters contour name and milling depth
(-1*BT).
 A G370 with the parameters of the figure.
 A G309.
