Graphics – applications, sectioning, threads, auxiliary views

Engineering Studies – H3 Aeronautical Engineering – Graphics

This topic reviews the graphical methods of representing objects in both pictorial and orthogonal views. It covers freehand techniques, scaled orthogonal drawings, and applying Australian Standards AS1100.

Key Concepts

• Graphical communication using orthogonal projection
• The importance of Australian Standards AS1100 for graphics, including:
  • Sectioning and section line types
  • Threads representation in a sectioned drawing
  • Projection of auxiliary views
• Applications of graphics including AR, VR and CAM

Discussion Questions

1. What are applications for using graphics as a communication tool?
2. Name examples of AS1100 standards that apply to:
   1. An orthogonal drawing?
   2. A pictorial drawing?
3. Why is freehand sketching with ‘to scale’ proportions important and in what ways does an engineer use freehand sketching?
