Abstract

A software control method and apparatus for implementing a knowledge-based polymorph undockable toolbar within an object scene. The undockable toolbar can be used to perform actions on objects created and managed by computer software applications. A knowledge-based polymorph undockable toolbar can merges into a relatively small area, tools for executing various commands that would require substantial screen space if represented by standard icons on a toolbar. The present invention can be used to manipulate non-constrained objects or groups of objects included in an assembly that are linked to each other by constraints. The knowledge based polymorph undockable toolbar can also act to reduce the number of user interactions needed to perform a manipulation task.
