Edge

X

Z

These measurements return the X and Z position of the edge point, respectively. The edge point is located half-way between the upper and lower data points of the step.

The sensor, or combination of sensors, that provides data for the tool's measurements. For more information, see Source.

One of the following: Step or Corner.

Step: Searches for steps on each path profile.

Corner: Searches for slopes on each path profile. When you choose this mode, several of the tool's parameters are hidden.

Determines which step the tool uses when there are multiple steps in the profile. An edge point is placed the chosen step. Steps must satisfy the tool's Step Threshold and Step Direction settings.

Best: Selects the greatest step on the profile.

First: Selects the first step on the profile.

Last: Selects the last step on the profile.

The minimum step accepted as an edge candidate. Steps on the profile are treated as absolute values when compared to this setting.

In the following profile, with Step Threshold set to 1.7 (and Selection Type set to Last), the tool accepts the step to the right, with a step of -1.873 mm, because it is above the step threshold.

In the following, when Step Threshold is increased to 1.9, the tool excludes the falling step to the right, because it is no longer above the step threshold, and instead uses the step to the left.

Determines whether the expected step rises or falls, moving left to right, along the profile. Either Rising, Falling, or Rising or Falling.

The size of the (moving) window along the profile used to calculate an average for each data point on the profile. The setting is useful for averaging out noise.

If Step Smoothing is set to 0, no averaging is performed.

The distance, along a path profile, separating the points the tool uses to find steps on a profile.

In the following, a step width of 5.5 mm causes the tool to consider profile points that distance apart as steps. Consequently, the curved portion of the profile is not used to measure the step.

The setting is useful when you must detect a slope as an edge, rather than a sharply defined edge: setting Step Width to a value greater than the width of the edge ensures that the tool measures the height difference between the flat regions on either side of the edge. As a result, the height of the step is accurately measured, and the edge is correctly located.

Setting Step Width wider than necessary can reduce the precision of edge location.

Fills in regions of missing data caused by an occlusion near the desired edge. Use this setting when continuity on the target is expected. When Max Gap is set to a non-zero value, the tool holds and extends the last data point on the low side next to an edge across a gap of null points, up to the distance specified in Max Gap.

The tool uses data points "filled in" by Max Gap before data points filled in by Null Fill Value (see below).

Indicates whether null points (points where no height value is available, due to dropouts or regions outside of the measurement range) are filled with the value in Null Fill Value as a general “background level.”

To find an edges next null points, you must use either this option and an appropriate value in Null Fill Value or Max Gap. Otherwise, only edges within areas of contiguous data will be detected.

The height value (in mm) used to replace null points when Include Null Edges is enabled.

If both Null Fill Value and Max Gap fill in null points at the same position, the tool uses the value extended by Max Gap, regardless of the value of Null Fill Value.

When disabled, reduces what is indicated in the data viewer.

The filters that are applied to measurement values before they are output. For more information, see Filters.
