If there is an existing center-line in a sketch, what will SolidWorks do regarding the axis of revolution?

When a center-line exists in a sketch in SolidWorks, the software recognizes this and automatically pre-selects it as the axis of revolution for the feature being created, such as a revolved feature. Center-lines are specifically designed to serve as references in sketches, and when creating features that require axis of revolution, SolidWorks utilizes these center-lines to simplify the process for users.

This automatic pre-selection streamlines the design workflow, as it eliminates the need for the user to manually select or define the axis of revolution when the software can readily identify an appropriate reference from the sketch. This feature enhances efficiency, particularly in complex sketches where multiple lines are present. It is important for users to understand the role of center-lines in their sketches and how SolidWorks leverages them to facilitate feature creation.
