Specifying pattern search rings
Search rings expand the area evaluated by the pattern tool beyond the current
field of view during CNC program execution. Each search ring expands the
pattern tool search in a clockwise series of rectangles. The size of each rectangle
depends on the pattern tool size and the search ring overlap specified.
During program execution, the initial field of view is evaluated. If the target
pattern is not found, and search rings were specified, the field of view is moved
to the lower-left corner of the first search ring. Then the pattern search contin-
ues as a clockwise series of (field of view) rectangles is added until a feature is
found.
If the target feature is not found, the search continues to the next ring, or stops
if no additional rings were specified.
Enter the number of desired the search rings into the Number of pattern... field.
