The bends in the cutting plane are NOT shown in the sectioned view. The sectioned view is created by rotating the cut features parallel to the viewing plane, showing the true size and shape of the features. Revolved Sections Revolved sections are simply cross sections of some part of an object. They are created by placing the cutting plane through the object at the point of interest and revolving the cross section at that location. This will show the true shape of the cross section.
Revolved sections are useful for spokes, webs, extrusions, structural members, etc.
Only the cross section cut by the section plane is crosshatched. The cross section is revolved at the location where it is cut from. The revolved section shows the true shape of the cross section. The revolved section can be revolved directly on top of the object as shown in the top object in the figure above. The revolved section can be placed in a broken-out gap in the object as shown in the bottom object in the figure above.
