Some of the beam processing features are based on rules .This means that when you modify a beam, the processing is also modified.
Cope parametric - rule or Cut at object are examples of such processing features.
As for connections, processing elements based on rules are controlled with a connection object, through which feature properties can be changed.
The connection objects are represented in the model as gray objects (boxes).
Connection objects (boxes) are displayed by selecting one of the processing objects created by the connection and using the Display tool on the Joint Utilities panel of the Extended Modeling tab or by right clicking on the processing object and selecting Advance Joint Properties from the menu.
The Feature representation style is required to display the connection object (box).
