Defining the digitizing range in a specific shape (only available
with measuring touch probes)

The digitizing range is defined by a contour point table generated in the
Positioning with MDI mode of operation. You can either transfer the
individual points by teach-in programming or move the touch probe
around the model manually and have the TNC generate them
automatically (see figure at right).
