The concept of a vision probe parallels a contact probe to a certain point. Obviously, a vision probe doesn't come in physical contact with the part, but both contact probes and optical probes use the term "probe tip" to specify various positions of an articulating probe head. (Some other interchangeable terms for "probe tip" are AB angles, AB positions, Tip, Tip Angles, and so on.) The actual tip on a vision probe contains the optical device (the camera).
If you select a probe from the Probes list or a probe tip from the Probe Tips list, PC-DMIS Vision inserts a LOADPROBE/ command or a TIP/ command into the Edit window.
When PC-DMIS Vision executes these commands, it performs its associated probe definition.
