About View Group Objects

A view group object exists to relate view ports and view devices. It defines the set of view ports and view devices that can interact with each other, and it provides the basis for their relative positioning.

A view group represents a two-dimensional coordinate plane called global space. Global space imposes physical dimensions on and defines the spatial relationships among the view ports and view devices that belong to a view group.

You can have several view groups. Each defines a drawing world, allowing you to separate groups of view ports and view devices and draw to each group without conflict.
