### Performing a Patch Advanced Scan

Scan dialog box — Patch Scan

The Patch Scan method will scan the surface of the part based on the Scan Parameters. The probe will always remain within the cut plane while doing each scan line. It uses the Increment value to determine the distance between points on each line. When the scan reaches the boundary at the end of a line, the scan will move to the next line by the Increment 2 value and start a new scan line moving in the opposite direction. The following figure describes this process.

The Patch scan is like a series of Linear Open scans done parallel to each other. | The Patch Scan method will scan the surface of the part based on the Scan Parameters. The probe will always remain within the cut plane while doing each scan line. It uses the Increment value to determine the distance between points on each line. When the scan reaches the boundary at the end of a line, the scan will move to the next line by the Increment 2 value and start a new scan line moving in the opposite direction.
