Used to quickly gather nominal features based on proximity.
Detect CAD Nominals by Proximity. This function looks at a CAD model, extracts the nominal features from it and associates them with the measured features. The Detect Nominal options for both CAD only consider the visually displayed features. If you hide parts of the CAD model they will not be considered for association. This provides the user the ability to control which objects are detected.
Detect SA Object Nominals by Proximity. This function looks for existing objects and both sets them as the nominal object for the geometry relationship and renames the measured feature using the nominal names.
Detect SA Object Nominals by Inter-Point Distance. This function looks for existing objects and both sets them as the nominal object for the geometry relationship and renames the measured feature using the nominal names. The advantage in this option is that it looks for spatial patterns in the layout of the selected features and nominal objects tries to match up based upon that, which can be done prior to alignment.
Select the desired option (either extracting features from CAD or identifying existing geometry)
If choose to link existing geometry using the Detect SA Object Nominals by Proximity option you will be prompted a second time to select a list of features to consider.
This dialog also offers search options including By name using Wildcard, By Color and by Object Type.
Choose a proximity tolerance to use. This constrains how close the nominal must be in order to be detected and assigned.
