A display group is a collection of selected model components and
can contain the entire model or combinations of part instances, geometry
(cells, faces, or edges), datum geometry (points, axes, planes, or coordinate
systems), elements, nodes, surfaces, constraints, and output database
coordinate systems.
Display groups allow you to reduce clutter on your screen and
focus on areas of interest within your model, to access “hidden” components in
complex models, and to decrease the amount of time needed to refresh the
display in the current viewport. For example, you can use display groups to
show contact surfaces but suppress elements or to produce a contour plot
showing elements in the interior of your model that would otherwise be
obscured. You can plot, save, edit, copy, rename, and delete display groups.
In
the Visualization module
you can plot more than one display group in the same viewport, and you can
customize the plot options for each display group independently.
