New objects can be created with the Add menu in the 3D View's header.
Meta Objects (or metaballs) are objects formed by a mathematical function (with no control points or vertices) defining the 3D volume in which the object exists. Meta objects have a liquid-like quality where when two or more metaballs are brought together, they merge by smoothly rounding out the connection, appearing as one unified object. See Meta Primitives.
Text Objects create a two-dimensional representation of a string of characters.
- Grease Pencil
Grease Pencil Objects are objects created by painting strokes.
Armatures are used for rigging 3D models in order to make them poseable and animateable.
Empties are null objects that are simple visual transform nodes that do not render. They are useful for controlling the position or movement of other objects.
Images are empty objects that display images in the 3D Viewport. These images can be used to support modeling and animating.
Lights for lighting the scene in renders.
- Light Probe
Lights are used by the Eevee render engine and record lighting information for indirect lighting.
This is the virtual camera that is used to determine what appears in the render. See Cameras in Cycles.
Speaker brings a source of sound to the scene.
- Force Field
Force Fields are used in physical simulations. They give simulations external forces, creating movement, and are represented in the 3D Viewport as small control objects.
- Collection Instance
Lets you select from a list of existing collections. Once selected, an empty object will be created, with an instance of the selected collection (collection instancing active). See Collection.
You can change the options of the object in the Adjust Last Operation panel just after creating it:
Some objects let you change their type after creation with a selector.
Sets the starting size.
Rotates the new object so that it is aligned in one of the following manners:
Aligns the object to the global space axes, i.e. the object's front faces the negative Y axis (default).
Aligns the object to the view space axes, i.e. the object's front faces the viewport's point of view.
- 3D Cursor
Aligns the object to match the rotation of the 3D Cursor.
Objects are placed, by default, at the position of the 3D Cursor. These values let you place the object in an other position.
Values let you rotate the object so that default rotation is overridden.
