The Sector Symmetry Feature node (

) defines a feature that implements sector symmetry for a pair.
The Settings window is almost identical to the
Generic Feature, except that it does not include the
Selection Settings section.
Select the Only use explicit pair looping over pairs check box to turn off the automatic looping over pairs, so no individual pair access is supported for the nodes under the pair feature and for links to normal components. Any pair looping then have to use an explicit pair looping with a component (see the
Loop list in
Component).
Select the Singleton feature check box if the physics interface only allows a single instance of the feature.
