Engineering Drawings for Manufacturing

Learn how to create complete, precise engineering drawings for manufacturing.

Introduction

• Prepare complete, industry-standard engineering drawings

1. Overview of Mechanical Drawings

• Prioritize clarity when preparing drawings
• Reference standards to clarify drawing interpretation
• Prepare a complete and succinct sheet template
• Select the correct drawing type for your part

2. Choosing and Placing Views

• Represent a 3D part in 2D using orthographic views
• Depict internal features with section views
• Enhance smaller features by depicting them in detail views
• Leverage 3D CAD to create pictorial views
• Use the correct line conventions to clarify geometry
• Challenge: Choose and place views
• Solution: Choose and place views

3. Dimensioning

• Follow the rules of dimensioning to prevent ambiguity
• Use the right style when placing dimensions
• Dimensioning tips: Angles, chamfers, arcs, and fillets
• Dimensioning tips: Holes and slots
• Dimensioning tips: Shafts, grooves, keyways, and threads
• Dimensioning tips: Symmetric and repeated features
• Dimensioning tips: Bent components
• Write clear notes for a complete product definition
• Challenge: Place dimensions for a sample part
• Solution: Place dimensions for a sample part

4. Tolerancing

• Limit a part's geometric variation with tolerances
• Take the guesswork out of setting tolerances
• Use GD&T to specify the functional requirements of parts

Conclusion

• The future of mechanical drafting
