Selecting and saving machining positions

Operating notes:
This function is not available if option 42 is not
enabled.
If the contour elements are very close to one another,
use the zoom function.
If required, configure the basic settings so that the
control shows the tool paths. Further information:
"Basic settings", Page 500
Three possibilities are available in the pattern generator for defining
machining positions:
Single selection: You select the desired machining positions by
clicking them individually with the mouse
Further information: "Single selection", Page 514
Multiple selection by drag box: You select multiple machining
positions by dragging a box around them with the mouse
Further information: "Multiple selection by drag box", Page 514
Multiple selection by search filter: You select all machining
positions within a definable diameter range
Further information: "Multiple selection by search filter",
Page 515
Machining positions are deselected, deleted, or saved in
the same manner as contour elements.
Selecting the file type
The following file types are available:
Point table (.PNT)
Klartext conversational language program (.H)
If you save the machining positions to a Klartext program, the
control creates a separate linear block with a cycle call for every
machining position (L X... Y... Z... F MAX M99).
The NC syntax used allows you to export NC programs
generated by CAD import to old HEIDENHAIN controls
and run them there.
The point tables (.PNT) of the TNC 620 and iTNC 530
are not compatible. Transferring a point table to and
running it on the other control model leads to problems
and unpredictable behavior.
