What is a Sectional View? Definitions and Examples of Sectional Drawings for Students

Sectional drawings show what an object looks like as if it had been cut open or sliced through.

Sections:

• Show a “cut through” view of an object
• Show how things are put together or assembled
• Cut surfaces have diagonal ‘hatching’ (angled parallel lines)
• Pins, bolts, nuts etc are not sectioned
• The ‘cutting plane’ shows where the object is cut (the arrows show the direction the section is viewed from)

Hatching guidelines

• Hatching lines should be parallel & evenly spaced
• Lines can be on any angle but must not be same angle as edge of object

• Each object should be hatched at different angle

including an understanding of how to hatch cut surfaces, nut and bolt conventions
