This video explains typical examples of conventional representation of various materials and machine components used in engineering drawing.
Certain draughting conventions are used to represent materials in section and machine elements in engineering drawings.
As a variety of materials are used for machine components in engineering applications, it is preferable to have different conventions of section lining to differentiate between various materials.
