The Adaptive Free Form Plane Scan strategy for the Plane Auto feature scans a plane by moving along a path defined by a set of points. The scan path can be continuous, contain a break, or contain move points. Break and move points in the scan path can help to scan a face as one single plane even if the path is not continuous due to any reason.
The path of the scan can be dynamically read from a text file when you run the measurement routine. This can help to scan the plane on variants of the part where the shape of the face being scanned is changed between variants.
The strategy's tabs are located in the Probe Toolbox in the Auto Feature dialog box (Insert | Feature | Auto | Plane):
