Select Object

Select Object lets you select objects or sub-objects for manipulation.

Main Toolbar > Select Object
Right-click to open quad menu. > Transform quadrant > Select

Object selection is affected by several other controls:

The active Selection Region type: Rectangular, Circular, Fence, Lasso, or Paint.
The active selection filter (All, Geometry, Shapes, Lights, and so forth).
The state of the crossing selection tool (which determines whether completely surrounded objects or surrounded and crossing objects are selected).

You can also select objects by name with the Select From Scene dialog > Select from Scene list; press the H key to access this dialog.

A number of objects selected together is called a selection set. You can name selection sets in the Named Selection Sets field on the main toolbar and then recall them for later use.

Note: The Smart Select command activates the Select Object function and, with repeated invocations, cycles through the available Selection Region methods. By default, Smart Select is assigned to the Q key; you can use Customize User Interface to assign it to a different keyboard shortcut, a menu, and so on.

Procedures

To add objects to a selection set:

Hold down the Ctrl key and select the objects to add.

Note: Adding objects doesn't change a named selection set.

To remove individual objects from a selection set:

Hold down the Alt key and select the objects to remove.

Note: Removing objects doesn't change a named selection set.

To select objects and move, rotate, or scale them:

Use Select And Move, Select And Rotate, or Select And Scale, available from the main toolbar and the quad menu > Transform quadrant.

When you rotate a selection set, the pivot of rotation depends on which option is selected on the Use Center flyout on the toolbar.

These tools are restricted to a specific axis or plane, which you can choose from the Axis Constraints toolbar or specify with the transform gizmo.
