1. If the Points List link source tool does NOT have a Tool Origin property (e.g. the Data Instance tool),
the link is made without a warning.
2. If the Points List link source property
contains "RWC" in the name (it uses Real World Coordinates),
and this tool’s Tool Origin is 0,0,0, the link is made without a warning.
3. If the Points List link source tool
has a Tool Origin property, and this tool’s Tool Origin matches it’s
value, the link is made without a warning.
The Multiple Point-to-Point Measurement tool Setup is designed to work with a fixed number of measure-
ments. The Setup configures the Tolerance List property based on the number of input points, which causes
the tool to always generate a specific number of measurements. The tool fails if the number of input points
does not match the number of Tolerances.
To match the number of configured measurements to the current point list length, push the "Rebuild Point
Table" button on the Setup tab.
To always make a dynamic number of measurements, based on the current length of the point list, use the
property panel rather than the tool Setup. Put a Data Set Tool that writes an empty Tolerance List to the Tol-
erance List input of the Multiple Point-to-Point Measurement tool before the Multiple Point-to-Point tool in
the task. That way, if you accidentally enter the tool setup and it configures the Tolerance List, that List is
overwritten the next time the task runs.
Peak Valley Find
In the Measurement Drawer
The Peak Valley Find tool is used to find and count maximums and minimums (peaks and valleys) along a
given edge direction. A wide line segment is used as a directed ROI to specify the search direction for edges.
Starting from the top of the ROI and running in the direction of the line segment, the tool finds edges and
detects peaks and valleys along the given direction.
Input Name What it is
Input Image Linked Image
Tool Origin The tool’s origin relative to the entire image space. Use this only if you
are trying to find an origin relative to another tool.
Report Peaks If True, the Peak List output is populated.
Report Valleys If True, the Valley List output is populated.
Report Edge Points If True, the Edge Point List output is populated. Use this primarily for tool
setup, since it will slow tool performance.
Wide Line ROI Points on this ROI are used for finding peaks and valleys along the edge.
The ROI direction indicates the edge and amplitude direction.
Edge Strength
Range
Specifies the range of percentage difference between detected edge pix-
els for peak and valley detection.
Minimum Amplitude The minimum distance, in the direction of the Wide Line ROI, between
successive peaks and valleys.
Output Name What it is
Peak List A list of peak edge points.
