Geometric Dimensioning Tolerancing Tutorial – GD&T Projected Tolerance in Engineering Drawings

Geometric dimensioning and Tolerancing or GD&T helps create more universally interpreted engineering drawing. The projected tolerance modifier is used for the long bolts or studs, which secure two mating plates. This geometric dimensioning and tolerancing tutorial will talk about the projected tolerance GD&T modifier and its application in engineering drawings. Engineering drawing is the communication tool among the mechanical engineers in industry. The whole intent of an engineering drawing is communicated by means of figures and suitable symbols. It is very important that the drawing conveys a single meaning to all its users, and here geometric dimensioning and tolerancing or GD&T plays an important role.
