#### Step 4: Construct Datum A

Once the 8 surface points have been measured in "Step 3: Measure Datum A Features" you can construct DATUM A from those points.

To construct DATUM A:

1. Execute the program up to this point to measure the 8 surface points. To do this:

1. Select Clear Mark . This is done so that the manual alignment point (PNT1) will not be included when you select Mark All.

2. Select Mark All from the Vision toolbar.

3. When the "Ok to mark manual alignment features?" message appears, click NO.

4. Select Execute . The 8 surface points will be measured.

2. From within the Edit Window, ensure that the LAST line in the part program is high-lighted.

3. Select the Insert | Feature |Constructed | Plane menu item or the Constructed Plane button from the Constructed Features toolbar. The Construct Plane dialog box appears.

4. Select the Best Fit option.

5. From the feature list, high-light the 8 surface points, measured in "Step 3: Measure Datum A Features". In this example, the points are 2-9.

6. Type DATUM A in the ID box.

7. Click Create, and then click Close to add the plane feature to the part program.
