The rotation element is formed by rotating the section around the axis in one or both sides at a given angle. For example, the following figure shows an element formed by rotating a sketch 270° around an axis lying in its plane.

The rotation element can be an independent solid, or it can be glued to the solid or cut out of it.
To create a new solid or to glue a rotation element to an existing solid (i.e., to add material), use the Revolution Element operation, and to cut a rotation element from the solid (i.e., to remove material), the Cut Rotation Solid operation.
A face, sketch, edge or spatial curve can be used as a section of the rotation element.
When rotating a face, a closed sketch (sketch area), a closed contour on the face, or a closed sketch contour, a choice is possible between a solid and a thin-walled element (see figure).

Rotation of the face: a) section and axis,
b) a solid element, c) a thin-walled element
With open section, as well as with the rotation of an edge or a spatial curve (including an Arbitrary), it is possible to build only a thin-walled element. An example of rotating a spatial curve is shown in the figure.
