Methods and devices are provided for providing a graphic overlay for measuring dimensions of features using a video inspection device. One or more measurement cursors are placed on pixels of an image of the object. One or more planes are determined parallel or normal to a reference surface or line and passing through surface points associated with the measurement cursors. A semi-transparent graphic overlay is placed on pixels with associated surface points having three-dimensional surface coordinates less than a predetermined distance from the plane(s) to help the user place the measurement cursors.
