1. Sectional Views

2. New Terms Sectional view Cutting-plane line Section lining
used to communicate more information about an object with complicated internal features than the conventional multi-view
Cutting-plane line
used to indicate the path that an imaginary cutting-plane follows to slice through an object
Section lining
used to illustrate where the object is sliced by the cutting- plane line

3. Kinds of Sections Full section Offset section Half section
Broken-out section
Revolved section (rotated section)
Removed section
Auxiliary section
Thinwall section
Assembly section

4. Full Section
Simply a section of one of the regular multiviews that is sliced or cut completely in two.

5. Offset Section
Shows features that do not fall in a straight line by bending the cutting-plane line

6. Half Section
Cuts halfway through and only a quarter section is removed

7. Broken-out Section
Used to show only a small area of feature to make it easier to understand.

8. Revolved Section (rotated)
Used to illustrate the cross section of ribs, webs, bars, arms, spokes or other similar features.

9. Removed Section
Similar to a revolved section except that the view is moved away from the regular views.

10. Auxiliary Section
Used to project the true size and shape. The cutting-plane is perpendicular to the axis.

11. Thinwall Section
Used to illustrate very thin materials being sectioned.

12. Assembly Section
When a sectional drawing is made up of two or more parts. Can be a full, offset, half or combination of sections.
