GR-Features and other Relationships offer quite a bit of automation control during the inspection process without any need for MP integration. This automation is controlled per feature through the features Trapping Controls which are accessed either directly through a features right-click menu or its Properties.
The primary benefit in pre-configuring features using Trapping Controls is to allow automated measurements to be built into an inspection process. These include operations such as:
Enabling Callouts and Watch Windows
Incorporating Guide Points or Guide Vectors for automeasure operations and visual guidance
Lock Out Trapping. This option provides the ability to hide the feature from the current inspection list and displays the features current status. Checking the Lock Out Trapping option will hide the feature from inspection. A multi-feature control for this option can be found in the inspection section on the home page.
Instrument Selection. Many operations are instrument type specific, so the instrument to be used should be selected first. If you have a single instrument in the job file it will be selected for you automatically. The current instrument selected is shown and the ellipsis button on the right can be used to re-select a different instrument.
Measurement is broken down into 3 separate categories
Trap Geometry. This corresponds to measurements that directly associate a measured geometry as the reference for a GR-Feature, creating a comparison only relationship.
Trap Clouds. Used for applications where point clouds are associated with a GR-Feature.
Trap Points or Vectors. Used for either point or vector measurement modes where the reference targets are used for guidance while trapping or measurement trigggering.
Group to Contain Measured Points. This control defines where measured points will be saved regarding the collection and Group name for the destination points. You can leave the collection name blank in order to save the measured group into the current working collection at the time of measurement.
Guide data. Choose either points or vectors to guide the measurement operation.
Auto Measure Guide Data. This check box will cause the instrument to perform an auto measure using the selected guide data, using either auto measure points or surface vector intersections of guide vectors are selected. For more information on these operations see:
Display Point Watch Window. This open will open a closest point watch window when guide points are selected, or a single watch window on the selected point for sequential measurements.
Ignore Points Beyond Threshold. This option compress the measurements to the nominal reference points and will prevent association of points that are further than the specified threshold from the guide points.
Use Proximity Triggers. Proximity Triggers can be used as part of a feature measurement.
Use the ellipsis button on the right to edit the Proximity trigger settings used with that feature trapping process. For more on Proximity triggers go Here.
Measure Point List Sequentially. This option allows you to walk through the list of guide points in order, one at a time.
View Zooming with Proximity. Offers guidance to a particular point using the Measure Guide Points Option.
The Apply to Selected section of the GR-Feature or Relationship Properties includes an option to apply the basic Trapping Control settings. Couple of notes on this:
Auto measure cannot be applied to others unless you select guild points first for all features involved.
This does not cover applying guide points, callouts or MPs. It covers the measurement controls.
Configure Instrument and Proximity Filters which are found within the Trapping Controls are handled separately and offer their own controls for Applying settings to others.
Information on Callouts, Linked MPs can be found Here.
