Setting the Dominant Object in a Selection

When you are resizing or aligning multiple objects, the Editor uses the dominant object to determine how the other objects are sized or aligned. By default, the dominant object is the first object selected. When multiple objects are selected, the dominant object has green sizing handles; all the other selected objects have aqua sizing handles.

Sizing handle colors may vary on different platforms, hardware or software.

Procedure

Select multiple objects.
Hold down the Ctrl key and click the object you want to make the dominant object.

Results

All further resizing or alignment is based on this object.
