Parameter Description
Point A point geometric feature generated by another tool.
Reference Feature A point or line geometric feature generated by another tool.
Dimensional measurements are calculated from the
reference feature to the point in the Point setting.
Filters The filters that are applied to measurement values before
they are output. For more information, see Filters on page
192.
Decision The Max and Min settings define the range that determines
whether the measurement tool sends a pass or fail decision
to the output. For more information, see Decisions on page
191.
Intersect
The Feature Intersect tool returns the intersection of a line geometric features and a reference line or
plane geometric feature. For line-line intersections, the lines are projected onto the Z = reference Z line
plane for features extracted from a surface, and the intersection of the lines projected onto the Y = 0
plane for features extracted from a profile. The angle measurement between the two lines is also
returned. The lines the tool takes as input are generated by other tools, such as
Surface Edge or Surface
Ellipse .
The Feature Intersect tool saves you from having to write complicated calculations in script tools to find
intersect point between lines. Previously, calculating the intercept point of two lines was difficult and
prone to bugs, involving finding lines in indirect ways.
The Feature Intersect tool's positional measurements are particularly useful as anchor sources. For
example, you can easily find a corner point on a part from two edges (produced by two Surface Edge
tools) and using the X and Y positions as anchor sources.
When you use these positional anchors in combination with a Z Angle anchor from tools such as Surface
Edge, you can achieve extremely robust, repeatable measurements.
This tool's Angle measurement cannot be used as an angle anchor source. Only Z Angle
measurements can be used as angle anchor sources.
For more information on anchoring, see Measurement Anchoring on page 194.
The Feature Intersect tool can also generate a point geometric feature representing the point of
intersection of the lines that the Feature Dimension tool can use in measurements.
Gocator compares the measurement value with the values in Min and Max to yield a decision. For more
information on decisions, see Decisions on page 191.
See Adding and Configuring a Measurement Tool on page 182 for instructions on how to add
measurement tools.
