Select Objects in Groups
There are several methods for choosing a group, including selecting the group
by name or selecting one of the members of the group.
By default, groups are selectable; that is, selecting any member of a group
selects all the objects in that group. You can then edit the group as a unit.
Selecting an object that belongs to multiple groups selects all groups to which
that object belongs. Turn off group selection to select grouped objects
individually.
TIP Toggle group selection off or on by pressing Ctrl-H or Shift-Ctrl-A.
All members of selectable groups are also selected when you use object selection
cycling (for example, if you want to select an object that lies directly behind
another object). To select groups for editing with grips, use the pointing device
to select the group at the Command prompt.
Edit Groups
You can modify groups in a number of ways, including changing their
membership, modifying their properties, revising the names and descriptions
of groups, and removing them from the drawing.
Edit Objects as a Group
When group selection is turned on, you can move, copy, rotate, and modify
groups just as you can modify individual objects. If you need to edit objects
within a group, turn off group selection or use grips to edit individual objects.
For more information, see
Select Objects in Groups (page 230).
In some circumstances, it is useful to control the order in which objects that
belong to the same group are selected. For example, a custom routine that
generates paths for numerical control devices might depend on a series of
contiguous objects in a specified order.
You can reorder group members in two ways: either change the numerical
position of individual members or ranges of group members, or reverse the
order of all members. The first object in each group is number 0, not number
1.
