LMI Technologies Gocator Series - Bounding Box

Gocator Line Profile Sensors: User Manual
Gocator Web Interface • 171
Parameter Description
Type Object area type is for convex shapes above the baseline.
Regions below the baseline are ignored.
Clearance area type is for concave shapes below the
baseline. Regions above the baseline are ignored.
Baseline Baseline is the fit line that represents the line above which
(Object clearance type) or below which (Clearance area type)
the cross-sectional area is measured.
When this parameter is set to Line, you must define a line
in the Line parameter. See Fit Lines on page 168 for more
information on fit lines.
When this parameter is set to X-Axis, the baseline is set to z
= 0.
Line
When Baseline is set to Line, you must set this parameter.
See Fit Lines on page 168 for more information on fit lines.

Parameters
Bounding Box
The Bounding Box tool provides measurements related to the smallest box that contains the profile (for
example, X position, Z position, width, etc.).
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 159.
See Adding and Configuring a Tool on page 156 for instructions on how to add measurement tools.
The bounding box provides the absolute position from which the Position centroids tools are
referenced.
When you use measurement tools on parts or sections, the coordinates returned are relative to
the part or section. You can use the values returned by the Bounding Box tool's "Global"(see
below) measurements as an offset in a Gocator script to convert the positional (X, Y, or Z)
measurements of other measurement tools to sensor or system coordinates (depending on
whether the sensor is aligned). For more information on Gocator scripts, see See Script
Measurement on page 238.
