PC-DMIS Vision automatically determines what type of feature to add to your measurement routine. Based upon the hits taken, auto features are guessed when the Quick Start window is open. The example below shows the process of guessing a Vision Auto Circle feature, but would be similar for any of the supported features (Edge Point, Line, Circle, Round Slot, Square Slot or Notch Slot).
To measure Vision Auto Circle using Guess Mode:
Select the View | Other Windows | Quick Start menu option. The Quick Start window appears.
Quick Start window
Take your first hit on the edge of the circle feature by using you machine's jog box, or by left-clicking on the feature's edge in the Vision tab. The Quick Start window updates and shows one hit (1/1) in the buffer and the guessed POINT feature.
Take your second hit on the edge of the circle in the same way as the first hit in a different location. The Quick Start window updates and shows two hits (2/2) in the buffer and the guessed LINE feature.
Take your third hit on the edge of the circle in the same way as the first two hits at yet another location. The Quick Start window updates and shows three hits (3/3) in the buffer and the guessed CIRCLE feature.
Guessed Measured Circle Hits
Click the Erase
Hit button 
if you are not satisfied with the location of any of your hits. The
hit is removed from the buffer.
Once the desired feature has been guessed, click Finish. The feature is added to your measurement routine.
