Working and assembly drawing.

Working drawings show individual parts with all measurements and specifications needed for manufacturing. Assembly drawings display how different parts fit together to create a complete product. These two types work hand-in-hand in technical drawing.

Orthographic views present an object from different angles using front, top, and side views. Imagine looking at a wooden chair from the front, then the side—each view gives different information. Sectional views cut through an object to reveal its internal structure, like slicing through a loaf of bread to see inside.

Consider a Nigerian carpenter building a wooden window frame. The working drawing shows measurements for each wooden piece separately, while the assembly drawing illustrates how all pieces join together. A sectional view would reveal the frame's depth and internal joints.

Understanding these views helps you read manufacturing instructions accurately.
