### Collision Tolerance

The CD module in Avail/NT will not work unless there is an OPENGL (shaded) view on the screen. | Collision Detection (CD) in PC-DMIS is designed to detect collisions between the probe and CAD surfaces. Collision tolerances are specified in the Collision Tolerances dialog box. This option can be accessed by clicking on the Tolerances button in the Probe Utilities dialog box.
