HEIDENHAIN ITNC 530 - CONVERSATIONAL PROGRAMMING User Manual page 261

Setting
The mode for point transfer on circles and circle
segments determines whether the TNC
automatically loads the circle center point when
selecting machining positions via mouse click
(OFF), or if additional points on the circle should
be shown as well.
OFF
Do not show additional points on the circle.
Assume the circle center point directly when
a circle or arc is clicked.
Enable
Do show additional points on the circle.
Assume each desired circle point by
clicking it
Mode for point assumption: Specify whether the
TNC should display the tool path during selection
of machining positions.
Please note that you must set the correct unit of measure,
since the DXF file does not contain any such information.
If you want to generate programs for older TNC controls,
you must limit the resolution to three decimal places. In
addition, you must remove the comments that the DXF
converter inserts into the contour program.
