Selecting

Selection determines which elements will be the target of our actions. Selections work on the current scene visible objects. Blender has advanced selection methods. Both in Object Mode and in Edit Mode.

Selections and the Active Object

Blender distinguishes between two different states of selection:

Active object in yellow, selected object in orange, and unselected object in black.

In Object Mode the last (de)selected item is called the "Active Object" and is outlined in yellow (the others are orange). There is at most one active object at any time.

Many actions in Blender use the active object as a reference (for example linking operations). If you already have a selection and need to make a different object the active one, simply reselect it with Shift-LMB.

All other selected objects are just selected. You can select any number of objects. In order to change a property or to perform an operation on all selected objects (bones, and sequencer strips) hold Alt, while confirming.

Mirror Selection

Reference

Mode:All Modes Menu:Select ‣ Mirror Selection

Select All by Type

Reference

Mode:Object Mode Menu:Select ‣ Select All by Type...

Select Active Camera

Reference

Select More/Less

Reference

Mode:Object Mode Menu:Select ‣ More/Less Hotkey:Ctrl-NumpadPlus, Ctrl-NumpadMinus

Their purpose, based on the hierarchical.

More

Less

Contrast the selection, deselect objects at the boundaries of parent/child relationships.

Parent

Extend Child

Extends the selection to the immediate children of the currently selected objects.

Select Grouped

Reference

Mode:Object Mode Menu:Select ‣ Select Grouped Hotkey:Shift-G

There are two ways to organize the objects in relation to one another. The first one is parenting, and the second is simple grouping. These relationships to an artist's advantage by selecting members of respective families or groups. Select Grouped uses the active object as a basis to select all others.

Children

Selects all hierarchical descendants of the active object.

Immediate Children

Selects all direct children of the active object.

Parent

Object Data

Selects every object that is linked to the same Object Data, i.e. the data-block that specifies the type (mesh, curve, etc.) and the build (constitutive elements like vertices, control vertices, and where they are in space) of the object.

Material

Selects every object that is linked to the same material data-block.

Instanced Collection

Select every object that is linked to the instanced collection.

Texture

Select Pattern
