Note: When an inactive object is selected, you also see only the bounding box for that
object.

Layers and Groups in the Layers Tab .
Rules for Transforming Selected Objects and Groups
The way you transform selected objects depends on how many objects are selected.
Transforming a Single Object
If you select a single object, the changes you make only affect that one object. All
unselected objects remain unaffected. For example, if you select a single object, transform
handles appear around that one object.

Transforming Multiple Objects
If you select multiple objects in the Canvas, changes made to one object are simultaneously
made to all others. Each transform occurs around each object’s own anchor point, so the
effect is the same as if you made the same transform to each object’s handles, one object
after another.
