Tips for Creating a Revolved Feature Using the Object/Action Workflow
With this method, you first create a section and then activate the Revolve tool.
When you use an existing sketch as a feature section, the selected sketch is copied into the feature section. The Revolve tool analyzes the selected geometry and creates default geometry. The default feature type depends on the selected geometry. For example, an open sketch produces a surface.
