#### Length box

High Point | The Length defines the length of the search region. If you have a value for Width, but leave the Length value 0, the Length value corresponds to the length along the minor axis of the current work plane.
Square Slot, Round Slot, Ellipse, Notch, or Line | The Length box displays the length of the feature.
Cone | The Length box displays the length of the cone. A positive Length value indicates that the centroid is towards the cone's tip (the end of the cone feature that has the smaller diameter). A negative Length value indicates that the centroid is towards the cone's base (the end of the cone feature that has the larger diameter).
Cylinder | For a hole, the Length box defines the nominal length of the feature. If you enter a Length value but do not define a depth, PC-DMIS equally divides the Length value by the number of rows indicated in the Levels box. The probe then works its way down the cylinder in increments until it reaches the indicated length value.

If a depth value is defined, the actual measured feature becomes the length minus the depth value.

For a stud, if the Sample Hits list displays a non-zero value, PC-DMIS will take an extra hit on the top of the stud in the center as long as the length value is a non-zero positive value. It then will compute the length of the stud.
