## Creating an Auto Square Slot

The Square Slot option allows you to define a square slot measurement. This measurement type is particularly useful when you do not want to measure a series of lines and construct intersection and midpoints from them. Square slots must be measured with five hits (or six if you select the Width Meas check box).

Square Slot Measured with Five Hits | Square Slot Measured with Six Hits

To access the Square Slot option, access the Auto Feature dialog box for a Square Slot (Insert | Feature | Auto | Square Slot).

Auto Feature dialog box - Square Slot

With the dialog box open, depending on your situation, use one of these methods to create the feature:

Creating by Using Surface Data on the Screen

To generate a square slot using surface data:

1. Click on the Surface Mode icon .

2. Using the mouse, click once on any surface near the square slot. PC-DMIS fills in the dialog box with information collected from the model.

3. Make any other modifications to the dialog box as needed.

4. Click Create.

Creating by Using Surface Data with the CMM

To generate a square slot measurement using surface data with the CMM :

1. Touch twice on the long side of the slot using the probe.

2. Touch the part on the short side of the slot.

3. Continue around the slot and touch the next long side.

4. Touch the last short side.

5. Make any other modifications to the dialog box and the Probe Toolbox as needed.

6. Click Create.

Note: The order of touches should be in a circular pattern (clockwise or counter-clockwise).

The Find Noms option should be selected from the Mode list for this measurement method. See the "Mode List" topic in the PC-DMIS Core documentation for additional information on nominals.

Creating by Using Wire Frame Data on the Screen

To generate a square slot using Wire frame CAD data:

1. Using the mouse, click once near the square slot. PC-DMIS fills in the dialog box with information collected from the model.

2. Make any other modifications to the dialog box and the Probe Toolbox as needed.

3. Click Create.

Creating by Using Wire Frame Data with the CMM

To generate a square slot measurement using wire frame data with the CMM:

1. Touch twice on the long side of the slot using the probe.

2. Touch the part on the short side of the slot.

3. Continue around the slot and touch the next long side.

4. Touch the last short side.

5. Make any other modifications to the dialog box and the Probe Toolbox as needed.

6. Click Create.

Note: The order of touches should be in a circular pattern (clockwise or counter-clockwise).

The Find Noms option should be selected from the Mode list for this measurement method. See the "Mode List" topic in the PC-DMIS Core documentation for additional information on nominals.

Creating without Using CAD Data

To generate the square slot without the use of CAD data:

1. Find the top surface using three hits.

2. Take two hits on one of the long sides of the slot.

3. Take one hit on each of the three remaining sides of the slot in a clockwise direction. (There should be a total of eight hits.)

4. Make any other modifications to the dialog box and the Probe Toolbox as needed.

5. Click Create.

Note: The order of hits should be in a circular pattern (clockwise or counter-clockwise).

Creating by Keying in the Data

This method allows you to key in the desired X, Y, Z, I, J, K values for the square slot.

1. Type in the desired X, Y, Z, I, J, K values for the feature into the dialog box.

2. Click Create to insert the feature into your part program.

See the "Mode List" topic in the PC-DMIS Core documentation for additional information on nominals.
