Enlargement Diagram

This diagram often uses a circle to give a detailed view of part of an object, as if the viewer was looking through a magnifying glass. This allows the viewer to see a close-up of part of an object while maintaining the view of the whole.
Exploded Diagram

This diagram separates the parts of an object so they are more visible and identifiable. This exposes parts which would normally be hidden by overlapping parts. Exploded diagrams help the viewer learn the names of parts, but don’t necessarily give an idea of the parts’ function. These diagrams are most useful for displaying objects with many tiny hidden parts.
Cutaway Diagram

This diagram peels back the outside layers of the surface a subject so the viewer can see the function of what lies underneath.
Cutaways can be used to show how the parts of an object fit together as instructions for assembly.

Cross-Section

This diagram takes a slice out of a subject so the viewer can see a single two dimensional surface representing its internal structure. Cross-sections are well labelled to indicate the names of the exposed parts. They are useful for showing object which would be impractical to actually slice in half.
Block Diagram

This diagram removes a piece of an object as if it was a slice of a cake. This allows the viewer to see a 3-D depiction of the inside of an area that would usually be hidden or impossible to reach.
