Feature Points

Dimensional and positional measurements detect feature points found within the defined measurement region and then compare measurement values taken at the selected point with minimum and maximum thresholds to produce a decision. Feature points are selected in one or more Feature dropdowns in a tool and are used for all of the tool's measurements.

The following types of points can be identified in a measurement region.

Point Type Examples

Max Z

Finds the point with the maximum Z value in the region of interest.

Min Z

Finds the point with the minimum Z value in the region of interest.

Min X

Finds the point with the minimum X value in the region of interest.

Max X

Finds the point with the maximum X value in the region of interest.

Average

Determines the average location of points in the region of interest.

Corner

Finds a dominant corner in the region of interest, where corner is defined as a change in profile slope.

Top Corner

Finds the top-most corner in the region of interest, where corner is defined as a change in profile shape.

Bottom Corner

Finds the bottom-most corner in the region of interest, where corner is defined as a change in profile shape.

Left Corner

Finds the left-most corner in the region of interest, where corner is defined as a change in profile shape.

Right Corner

Finds the right-most corner in the region of interest, where corner is defined as a change in profile shape.

Rising Edge

Finds a rising edge in the region of interest (moving from left to right).

Falling Edge

Finds a falling edge in the region of interest (moving from left to right).

Any Edge

Finds a rising or falling edge in the region of interest.

Median

Determines the median location of points in the region of interest.
