INTRODUCTION FOR ENGINEERING DRAWING UNDERSTANDING

This course covers the majority of information required to understand basic mechanical two-dimensional engineering drawings. Topics covered are:

• Basic drawing elements (formats, title block, parts list, revision block, etc.)
• Part views (multiview, auxiliary, and isometric)
• Section views
• General dimensions
• Tolerances

COURSE OBJECTIVES

This training helps participants :

• Describe the fundamentals of drawing interpretation
• Identify drawing elements, including part views and sections
• Describe general dimensions and tolerances
• Explain how to present surface texture

INTENDED AUDIENCE

Beginning designers, drafters, quality, procurement, tooling, production, manufacturing and shop personnel; more advanced designers, and those involved with tooling, production, inspection, routing in the shop; others involved with purchasing, costing and management; vendors and suppliers.

METHODOLOGY

• This workshop will be interactive and action based with personal examples.
• Feedback from the trainer on your own writing.
• Participants are to bring along their drawings for discussion.
