Setting Description
Bounding Box or Ellipse .
Z Angle Corrects the orientation of the bounding box or ellipse to accurately match
typical orientation and simplify measurements.
Asymmetry Detection
Rotates scans based on the asymmetry of the scanned part.
Gocator calculates the number of points on each side of the part's centroid in the
bounding box or ellipse.
Along Major Axis
– The scan is flipped so that the greater number of points is
to the left.
Along Minor Axis
– The scan is flipped so that the greater number of points is
on the bottom.
None
– The scan is not flipped.
Acceptance Criteria Determines the minimum and maximum acceptable values of the selected
dimension (Width and Length for bounding box, Major and Minor for ellipse) in
Match Result .
Configuring a Bounding Box or an Ellipse
To use a bounding box or an ellipse to match a part, you must set its dimensions, taking into account
expected acceptable variations when compared to a reference (or "golden") part.
To configure a bounding box or ellipse for part matching:
1. Go to the Scan page.
a. In the Scan Mode panel, choose Surface .
You must choose Surface in order to scan a part. Furthermore, the Model page is only displayed in
Surface mode.
Intensity data is not used when part matching using a bounding box or an ellipse, but you can enable the
Acquire Intensity option if you need intensity data for other reasons.
b. In the Part Detection panel, choose Part for the Frame of Reference .
