Operators execute an action as soon as the operator is started which make them different from tools which require some sort of input. Operators can be started from a Operator Buttons, Header Menus, or Menu Search. Examples of operators include adding a new object, deleting it, or setting its shading to smooth.

Operator Properties

Most operators have properties that can be adjusted to refine the result of the operation. To adjust an operators properties, the operator must first be executed. This will execute the operation with its default property values. These properties can then be adjusted using Adjust Last Operation.
