Question

which feature is circled? revolve sweep extrude loft

Explanation:

In 3 - D modeling, the revolve feature creates a 3 - D solid or surface by revolving a 2 - D sketch around an axis. The icon resembles the concept of rotation which is characteristic of the revolve operation. Sweep creates a 3 - D shape by moving a 2 - D profile along a path, extrude pushes a 2 - D shape in a linear direction to create a 3 - D object, and loft creates a 3 - D shape by blending multiple 2 - D profiles.
