366 | Chapter 17 Change Existing Objects
In some ways, groups resemble blocks, which provide another method of
combining objects into a named set. For example, the groups you create are
saved from session to session. However, you can edit individual objects in
groups more easily than you can edit them in blocks, which must be
exploded first. Unlike blocks, groups cannot be shared with other drawings.
Create Groups
When you create a group, you can give the group a name and description. If
you copy a group, the copy is given the default name Ax and is considered
unnamed. Unnamed groups are not listed in the Object Grouping dialog box
unless you select Include Unnamed.
If you choose a member of a selectable group for inclusion in a new group,
all members of that selectable group are included in the new group.
The objects in your drawing can be members of more than one group, and
groups themselves can be nested in other groups. You can ungroup a nested
group to restore the original group configuration.
Named groups are not maintained when you use a drawing as an external ref-
erence or insert it as a block. However, you can bind and then explode the
external reference or explode the block to make the group available as an
unnamed group.
Note Avoid creating large groups containing hundreds or thousands of
objects. A large group reduces the speed of AutoCAD significantly.
