#### Adding Feature Variables

You may need to add new feature variables into the Data Editor tab.

1. Select the Data Editor tab. If it is not available, select Tools | View Selection and mark the Editor check box.

2. Click on the Measurement Data tab.

3. Right-click anywhere in the grid and select New Variable from the resulting short-cut menu. The Create New Variable box appears.

Create New Variable

FeatureName - This value determines the base name for the feature.

Axis ID - This determines the ID for the axis.

Nominal - This determines the nominal value.

Upper Tol - This determines the upper tolerance.

Lower Tol - This determines the lower tolerance.

Example of a T Variable Addition

For example, if you wanted to add a T variable for a circle of CIR1:

1. Type CIR1 in FeatureName.

2. Type T in Axis ID.

3. Type 0.000000 for the Nominal.

4. Type 0.000000 for Upper Tol. and Lower Tol.

5. Click OK. Datapage+ will take a brief moment to add the new feature variable into the database and refresh the screen.

This would create a CIR1.T feature variable as a new column in the Data Editor. Initially it would have empty (NULL) values, but you could then add in data and further manipulate the variable as needed.

A Sample T Variable in the Data Editor with Edited Values

The new feature variable also appears in the Feature Variable side bar. If you want the new variable to appear in alphabetical order, right-click on the Feature Variable list and clear the Measured Order check box and then reapply your selection to the Data Editor tab.
