- Assignment – Drawing CAD 102-1ns

Module 1 – Introduction, Orthographic Projection

Objectives:

- Discuss the Syllabus and Outline
- Power Point Presentation on Orthographic Projection
- Discuss 1^st angle vs 3^rd angle projection
- Discuss the miter line

Notes:

1. Use geometry in 3^rd angle projection
  1. Defined layers
  2. Defined line weights
  3. Defined line style
2. How the Miter line solves the missing view
  1. 45 degree line transitions projections
  2. Why not deleting/erasing construction lines
  3. Modelspace =full scale
  4. Paperspace = need scale
3. How to project tangencies and foreshortened planes

Assignments:

- Read textbook chapter on multiview/orthographic projection
- Print out Drawing CAD 102-1
- Using your new understanding of Orthographic projection solve CAD 102 A (in the syllabus).
- Select an appropriate "template" (ANSI/ISO)
- Assign your own dimensions to the part
- Then in model space using proper layers, construction, and miter line
- Solve for the FRONT, TOP, and Right Side of the part.
- Do not erase/delete construction lines or the miter line
- Go to Paper-Space and locate the three views of the part
- Viewport. Set an appropriate scale. Apply dimensions.
