Probes
Finding the pattern
Patterns can be found inside or outside the field of view. In either case, to begin a search for a pattern, select
the Pattern Finder probe and fire it by clicking the center mouse button. When the pattern is contained
within the field of view, the Pattern Finder probe will be automatically positioned over the pattern and
will return a point located at the center of the probe box. Then the probe will be returned to its original
location.
The measurement result is a point and is sent to
the Features template and the Results window.
Point measurement results include:
• The feature type and feature number
• The number of points acquired and the
number of points used to calculate feature data
• The geometric center location of the pattern
• The form value
If the pattern is located outside the field of view, and if search rings were specified in the Tools/Options/
VED setup screen, the system will begin a systematic clockwise search of rings of areas outside the current
field of view to find the pattern.
NOTE
Details regarding the setup of Pattern Finder search rings are contained in the VED screen
portion of Chapter 10: Supervisor Setup Chapter 10: Supervisor Setup.
