Operators execute an action the moment they’re activated, which makes them different from tools (which require some sort of input). Operators can be started from 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 their result. First run the operator (which will use its default settings), then adjust the properties in the Adjust Last Operation region.
