      </table><br><p class="para_topic">The <b class="uiTerm">Measure Faces</b> dialog calculates area and perimeter values of body faces. You can also perform the calculation in different analysis units. When you save a face measurement the system creates multiple expressions for area and perimeter. The display of the face measurement has an option menu to show either the area or perimeter.  However, when you save the measurement, the software always creates both expressions.
