Course: Engineering Drawing and Design (21106-36) > Section: Producing Illustrations

Creation should show the complete surface or surfaces of an object laid out on a flat plane. These may include

- products made of different materials (e.g., sheet metal, plastic)
- parallel-line development
- cylindrical surfaces
- conical surfaces
- radial-line development
- development of curved surfaces through triangulation
- spheres
- intersecting prisms
- tabs and fold lines.

Process/Skill Questions:

- What is the purpose of a surface development?
- What is a line of intersection?
- What tools and options in CAD enable us to create the pattern for a cylinder or a rectangular pyramid?
