The Object Toolbox is used to create Object diagrams, which reflect multiplicity and the roles that instantiated Classes could serve. They are useful in creating different cases in which relationships and Classes are applied.
Object Toolbox pages
Except where discussed here, each element and relationship that you can create using these Toolbox pages is described in the UML Elements and UML Connectors sections of the Help.
A Boundary is a stereotyped Object that models some system boundary, typically a user interface screen.
A Control is a stereotyped Object that models a controlling entity or manager.
An Entity is a stereotyped Object that models a store or persistence mechanism that captures the information or knowledge in a system.
