What is the difference between a revolved section and a removed section?

Answer 1

Revolved section shows only the features on the cut plane. It is used to depict the section of

an elongated object without the need to show the entire sectional view. Instead of

projecting the section onto an adjacent view, the resulting section obtained from the cutting

is revolved 90° and is placed on the same view

while Removed section is similar to revolved section in that only the cut plane is shown.

However, the section is placed elsewhere on the drawing

Answer 2

A revolved section is created by revolving a 2D shape around an axis to generate a 3D shape showing an internal view. A removed section is created by cutting away part of an object to reveal its internal features without revolving the section.
