Overview of Groups
A group is a saved set of objects that you can select and edit together or
separately as needed. Groups provide an easy way to combine drawing elements
that you need to manipulate as a unit. You can create them quickly and with
a default name.
TIP Groups are useful in associating 3D solids when you do not want to combine
them with a Boolean operation.
You can change the components of groups as you work by adding or removing
objects.
In some ways, groups resemble blocks, which provide another method of
combining objects into a named set. For example, groups 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
In addition to choosing the objects that will become the members of a group,
you can give the group a name and description.
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.
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.
When group selection is on (PICKSTYLE system variable set to 1 or 3), selecting
a member of an existing group for inclusion in a new group, selects all members
of the former group. To enable individual selection of grouped objects turn
group selection off (PICKSTYLE set to 0 or 2).
Named groups are not maintained when you use a drawing as an external
reference 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 significantly degrades the performance of this program.
