## Working with Measurement Strategies

You can use measurement strategies for specific Auto Features to select predefined schemes that change the way PC-DMIS measures those features. The following tables lists the measurement strategies that are available.

Auto Feature | Measurement Strategy
Circle |

- Adaptive Circle Scan

Cone |

- Adaptive Cone Concentric Circle Scan

- Adaptive Cone Line Scan

Cylinder |

- Adaptive Cylinder Line Scan

- Adaptive Cylinder Concentric Circle Scan

- Adaptive Cylinder Spiral Scan

- Cylinder Centering Thread Scan

Line |

- Adaptive Linear Scan

Plane |

- Adaptive Plane Circle Scan

- Adaptive Plane Line Scan

The Default PC-DMIS measurement strategy is the default touch point strategy. It is available for all Auto Features that support measurement strategies.

Note: For best results for all measurement strategies, the PC-DMIS Settings Editor should have VHSS enabled.
