The Time Project
Lesson 2: Orthographic Drawing

The drawing below shows a clock mechanism that may be placed inside a clock body made in the school workshop. We call the mechanism which is manufactured in large numbers a Standard
Component.( The drawing is not drawn to British Standards 308). The Drawing has no centre lines or construction lines. The images are also in the incorrect positions.

When making a product it is not always necessary to make all the components or parts. Standard components can be easily purchased.
