Multi-FeatureTrapping

Multi-feature trapping provides an advanced means to measure into a group of features at one time. This mode is accessible through a Right-Click on the Next button in the Inspection bar:

This will the offer a prompt which allows you to choose between two modes of measurement (either geometry or clouds):

 

An additional prompt will then be provided to select which features to consider: 

 

And then finally the selected features will be set into a monitoring mode, waiting for measurements to arrive:

 

Geometry Measurements

Geometry measurements are a specialized operation specific to instruments that can both scan and perform geometry fit operations on board the instrument (Instruments such as the ATS800 and Laser Radar. The measurements that are sent to SA in this scenario are the resulting fit geometry.

The way this operation works is each feature waits for a measured geometry to be sent to SA. If the geometry is within a preset proximity tolerance to the nominal feature then the geometry is assigned to the feature, the GR-Feature is converted to a comparison only feature, and taken from the list.

The Proximity tolerance settings are found within the Trapping Controls dialog for each feature.

 

Point Cloud Measurements

Multiple features can also be selected at one time when using a line scanning and scanning point clouds. This is process is also initiated with a Right-click on the next button in the Inspection Bar as shown above.

Cloud scanning works as a post processing operation. First select the features you want to measure, scan the part, and the press the Stop trapping button. At this point the cloud is assigned to the selected features and the individual feature cloud filter settings are used to extract the local data for the feature.
