What tool is used to create a new plane that is parallel to a selected plane or face?

The tool that is used to create a new plane that is parallel to a selected plane or face is the Offset Plane. This tool allows you to specify a distance from an existing plane or face, generating a new plane that maintains the same orientation as the original one.

Using the Offset Plane is particularly useful in design scenarios where you need to establish additional working planes for features such as sketches, cuts, or extrusions parallel to existing surfaces, without modifying those surfaces. This functionality streamlines the modeling process by enabling duplicates of existing orientations that can be adjusted with relative ease.

The other options, while potentially related to creating or modifying planes, do not specifically support the feature of generating parallel planes in the same way. The Coincident Plane relates to aligning planes at a common edge or point, while Control Plane and Parallel Plane do not represent standard tools within Solid Edge for generating new planes that maintain parallelism with an existing plane or face.
