To Position the Probe
When you play the probe path, the position of the probe on the screen corresponds to the position of the cursor in the DMIS data listing in the top portion of the PLAY PATH dialog box.
To change the probe position, use one of the following methods:
Click the Position Probe button in the lower portion of the PLAY PATH dialog box and select a point on the tool path to position the probe.
Select a line in the DMIS data listing, then click DMIS File > Position Probe to position the probe at this line.
