Blueprint Reading

Course Description
Basic Blueprint Reading is designed to familiarize participants with projection methods, procedures, and protocols for interpreting engineering drawings. During training, students will review and reinforce theories and principles of shape and size description by applying accrued skills on formal working drawing packages. Emphases of training include: practical implementation of ANSI/ASME Y14.5-2009 dimensioning and tolerancing practices, and understanding welding symbols as well as detail and assembly drawings for both machining and sheet metal products.

Who Should Attend
Basic Blueprint Reading is appropriate for anyone who needs to be able to understand and interpret the information found on mechanical drawings, including: machinists, machine operators, customer service representatives, salespeople, quality inspectors, assemblers, estimators, and production planners.

Learning Objectives
Upon successful completion of Blueprint Reading, students will be able to:

  • Read, understand, and interpret engineering detail and assembly drawings
  • Recognize and understand ANSI/ASME Standard Y14.5-2009 symbols and rules
  • Recognize and understand ANSI/AWS A2.4 symbols

Course Outline

1. Units
United States Customary System and Metric System

2. Graphical Solutions/Mechanical Design Conventions
