### Move Feature (Move To/ Point To)

Move Feature dialog box

The Move Feature dialog box is available when using either a Leica Tracker or a Leica Total Station device. It appears when you select the Move Feature toolbar icon on the Tracker Operation toolbar or on the Total Station Operation toolbar. You can also access it by selecting the Tracker | Move Feature or Total Station | Move Feature menu items.

The Move Feature dialog box contains the Move To and Point To options. These commands are used only with the Leica Total Station or Leica Tracker devices. In addition to the standard move ability of other DCC systems, the Point To command exploits the unique capabilities of these tracker-type systems by using the device as a laser pointer to identify directly on the part the location of out-of-tolerance points.

Move To

This option moves the device to a specific location where it then tries to find a reflector.

To move to a point, select the Move To option and then define where it should move to. There are three ways to specify the location to which it should move.

- Method 1: Type the values into the X, Y, and Z boxes (or R, A, and Z if the Polar option is used).

- Method 2: Select the feature that you are going to move to out of the Feature list. When you select the feature, PC-DMIS will fill in the X, Y, and Z values based on the centroid of the feature.

- Method 3: Expand the feature by selecting the + symbol next to it to display the hits on the feature. While "hits" is something of a misnomer, it simply means the point measured by the laser device. Select one of the hits from the list. PC-DMIS will fill in the X, Y, and Z values for that hit.

You can choose to move to the measured or the theoretical value for the point by choosing either the Theo or Meas option.

Once you have set up the command correctly, click Create to insert the command into the Edit window.

When PC-DMIS executes this command, the device will automatically move to the position indicated and attempt to find a reflector. If no reflector is found, an error will be displayed that says "AUT_FineAdjust - Request timed out". To get past this error, if there is a nearby reflector, you will need to use the Execution Options dialog box and stop the execution, adjust the location to point nearer the reflector, and then click Continue. If a reflector is not close by, you can click Skip to move onto the next point.

Point To

To point to different hits, the procedure is the same as the "Move To" information above, but there are some additional options. With Point To you can also select from available dimensions in the part program. If you select a dimension, PC-DMIS displays the Point To Filter and Point To Method areas. You do not need to select individual hits in the expanded dimension. All hits visible in the dimension will be pointed to, although you can use the Point to Filter area to filter hits.

Point to Filter

The Point To Filter area displays options that control which hits are pointed to. The options include:

- All – PC-DMIS will point to each point in the dimension.

- Min/Max – PC-DMIS will identify and point to only the Min and Max points.

- Out Of Tolerance – PC-DMIS will point to only out-of-tolerance points.

- N Worst – PC-DMIS will point to a number of "worst points". These points may or may not be in tolerance. This is a simple sort of the data based on the proximity to the theoretical values.

When you choose one of the options in the Point to Filter area, PC-DMIS updates the list of hits for the selected dimension in the dialog box to reflect the points to which PC-DMS will point the laser beam. For example, if you select Min/Max, the list of hits in the selected dimension will update with only two hits in the list, representing the min and the max points for that dimension. If you choose All, the list will update displaying all of the input hits of that dimension.

Point to Method

The Point To Method area lets you indicate how the device cycles through the list of points. The options include:

- None – No delay or user input is needed to move to the next point. It points to each of the points without delay just as soon as the device can physically proceed to the next point.

- Delay – This delays the cycle time by a specified number of seconds. When executed, the device will point to the first point in the list, turn on the laser and wait the specified amount of time. When the time expires, the laser will turn off and the device will move to the next point and repeat this process until all of the points in the list have been pointed to.

- Next Move Button – During execution, a Point to Execution dialog box appears showing the index of the point in the list along with its location.
  The dialog box has a Next and Cancel button, allowing the operator control over when to point to the next hit in the list. The device will move to the first point, turn on the laser and then wait until the operator clicks Next. It then moves to the next point in the list.

If you want to validate the command before creating it, click the Test button. PC-DMIS will move to the indicated position or point to the list of hits.

The command can be edited using the Edit window's Command mode or from the dialog box by selecting the command in the Edit window and pressing F9 on the keyboard.
