Trapping Vectors and Verification Mode
The Gear / Options icon in the inspection bar opens additional controls for inspection including the Global Trapping Options:
Enable Trapping Auto Vectors
Enable Trapping Auto Vectors offers an option to automatically turn on an auto vector group for the GR-Feature that is actively being trapped. It builds a vector group called “Trap Vectors: [Relationship Name]” in the tree and this vector group updates automatically as inspection progresses from one feature to the next.
This vector display can be used both during measurement and during part analysis to visualize deviations between the measure points the fit geometry.
See a YouTube demonstration Here
Expectations with Trapping Vectors Enabled:
-
Trapping vectors display the point to Measured Object (AVF) vectors for geometry relationships (GR-Features) or the point to object vectors for traditional relationships.
-
When inspection advances to the next feature in the inspection tab this vector group is automatically replaced by a new one representing the current feature. When trapping stops the vector group is then deleted.
-
Should an auto vector group already exist for a particular relationship in the tree it status will remain unaltered and trapping vectors will not be created for this feature.
Verification Mode
This option was added to provide greater clarity to the user on the results of a feature inspection. It adds an additional step to the inspection process during which the results can be reviewed before continuing to the next feature.
Expectations with Verify Mode Enabled:
-
When trapping begins and during the measurement process no difference will be seen. You can enable Trapping Vectors if you wish more feedback during the measurement.
-
When the Next button is pressed to advance to the next feature in the inspection list, which an also be accomplished with an instrument button press or the F7 key, the following will occur:
-
A different audible sound will be played if the feature passes or fails.
-
The Feature Pass / Fail result is displayed in the HUD. When a GR-Feature fails the first criteria in the list that failed is shown in the HUD as well as the features RMS. This provides both feedback on the quality of the measurement and why the feature did not pass inspection.
-
-
Pressing the Previous button will clear the feature data associations for re-measurement.
Vector Display Expectations with both Trapping Vectors and Verify Mode enabled:
-
If a feature already has auto vectors displayed then the status of these vectors will not be altered by the mode selection.
-
If a GR-Feature does not have a nominal defined, and does not have auto-vectors enabled, then its fit vectors (AVF) will be displayed.
-
If the feature does have a nominal defined, then the points to nominal vectors (AVN) will be shown.
Both trapping vectors and the verification mode can be enabled at the same time. If you have a GR-Feature as the target you will then see the fit (AVF) vectors during measurement and then it will switch to display the point to nominal deviations AVN during the verification step.

Note- that in 2024.2, trapping vector display is not yet available for GD&T feature check inspection. In addition no vectors will be displayed when Point Sets, Clouds or Nominal Geometry are associated.
