Technical drawings are used to define how a part should be manufactured and inspected, or to explain how the different parts of a system fit together. Ultimately they are tools that engineers use to communicate, so being able to understand them is an important skill.
Engineering Drawings
Engineering drawings are documents that provide all of the information needed to construct a part, including dimensions, tolerances and materials.
Geometric Dimensioning & Tolerancing
GD&T is a tolerancing approach that extends traditional dimensional tolerancing to allow you to control 14 different geometric characteristics.
Bolted Joints
Bolted joints are everywhere, but the underlying mechanics of a bolted joint are more complex than you may think.
