Course Overview

Course in a Nutshell

This course teaches how to interpret the views, callouts, and other information communicated on mechanical drawings. You will gain a complete understanding of all aspects of blueprints, from reading the title block to visualizing a three- dimensional part from a two-dimensional rendering. Other topics include: section views, dimensioning and tolerancing practices, and special callouts for screw threads, surface finish, and an introduction to GD&T.


Customize It!

Based on the knowledge base of your group, and the types of products you work with, we can customize the course to your specific needs. We also encourage participants to bring actual prints/drawings to the course for a discussion of the proper interpretation for your products. If sample prints are provided, the course can be turned into a workshop at no added cost.

While the course is mainly designed around the Y14 standards (ASME), it can be customized to accommodate other standards, such as the internal company standards for your prints.


Learn How To

  • Interpret different styles of lines shown on a print
  • Visualize an object based on the given flat images
  • Recognize first-angle projection and third-angle projection drawings
  • Interpret the title block and the information it contains
  • Use auxiliary and section views to supplement your understanding of a part
  • Describe symbols and instructions for special machining processes
  • Interpret various dimensioning methods and the allowable tolerances


Audience / Prerequisites

Aimed At
