Course Catalogue.

After participating in this course, you will be able to:

• Identify the main views in an orthographic projection drawing
• Explain the meaning of the different types of lines
• Visualize a 3D object from the 2D orthographic views
• Interpret plus/minus, nominal, reference and limit dimensions
• Explain the various elements found in a title block

Description
This webinar aims to provide participants with the skills and knowledge to interpret the main aspects of a mechanical drawing. Some people have the innate ability to visualize objects in three-dimensional space from a two-dimensional drawing. However, anyone can accomplish this when some basic rules are in place and can even be honed with practice.

The webinar will begin with a discussion of the drawing categories and the meaning of each line type. Then, a significant focus will be placed on interpreting and visualizing orthographic projection. Also covered are auxiliary information on a print (such as the title block and notes), section views, interpreting dimensions/tolerances, other special symbols (such as roughness callouts and screw threads), and an overview of the GD&T system of tolerances. Multiple examples will be provided to show specific applications.

Who Should Attend
Product Engineers • Manufacturing Engineers • Quality/Inspection personnel • Machine Operators • Purchasing and Cost Estimators • Support staff who handle prints
