Being able to read and understand, as well as sketch, or even draw a blueprint, is important to the making of accurate parts and complete fabrications.

Blueprints are tools that communicate what needs to be built or made, what materials are needed and what specifications are required. They insure that a design is made with complete accuracy what meets the needs of the customer.
