Groups are collections of different elements that can be handled at once by several tools. A group may contain any random collection of elements that are otherwise unrelated.
Create and name groups
A set of similar types of objects as well as random objects of a model can be organized in named groups. By organizing elements into groups, you can control the visibility of several objects and reduce the visual complexity of a model.
Modify group content
A group may contain any random collection of objects that are otherwise unrelated. In some circumstances it is useful to identify the objects of a selected group within a model. The objects of a group can be highlighted.
