Engineering CAD software is a constantly evolving tool that allows engineers to design more rapidly and efficiently than ever before. However, one basic element that has been consistently required over time is a detailed drawing. Drawings are the key piece of communication between Engineers, Machinists, Fabricators, Vendors and Customers.
An important and critical way an Engineer conveys the design intent within the drawing is with the use of GD&T (Geometric Dimensioning & Tolerancing). This isolates the functional and non-functional features, and creates a relationship from one feature to the next. GD&T provides a lot of information regarding how a part or assembly will be manufactured or assembled. Most importantly, it allows for repeatability for parts and assemblies in order to ensure that consistent quality is achieved. Below please find seven tips on using GD&T and things to consider when adding GD&T to your drawing:
