Hole on lateral surface
This function 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 (see page 411).
ICP generates:
 The SURFACE section code with the reference dimension
parameter. In nested contours, ICP generates only one section
code.
 A G308 with the parameters contour name and milling depth (–
1*BT).
 A G310 with the parameters of the figure.
 A G309.
