Transition Piece Developments


Engineering Studies – H3 Aeronautical Engineering – Graphics

This topic covers the techniques used to produce true shape patterns for transition pieces. The key concepts include applications of true lengths in construction developments using triangulation.

Key Concepts

  • The concept of shape development
  • The process of constructing true shape developments
  • Applications of transition pieces

Discussion Questions

  1. What does the term ‘transition piece’ mean in graphics?
  2. What does the term ‘triangulation’ mean in graphics?
  3. What is the purpose of developing true shapes of transition pieces?
  4. Explain how a 3D shape can be developed as a true shape in 2D.
