### Step 7: Defining Feature Frames

Feature Frames are only necessary for machines with more than three axes. If NCGage is installed on a 3-axis machine, Feature Frames will not be available or required. Once the Work Offset has been selected, the Work Offset button will change to the Define Feature Frame button. A Feature Frame can be defined anywhere in the program provided it appears after the Work Offset command. There can be any number of Feature Frames defined in a program.

For information on defining Feature Frames, see "Feature Frame" under the "Creating Feature Commands" section.

Once you have finished defining the Feature Frame, you can begin adding features to measure into your part program. See the "Creating Feature Commands" topic.
