Assignment 5
Special Views

Due at the end of our ‘Lecture’ meeting in Week 4
All items drawn with pencil on
8 x 11 paper

Concept Sketches:

  1. Sketch the design of the part(s) that satisfy the part drawing requirements below. Sketch freehand using any combination of orthographic or isometric views. Include a title at the top, some reference to size, material, how it will work and how it will be made. Include your name, signature and the date.

Working Drawings:

  1. Produce enough complete part drawings to demonstrate the use of various special views including: section (p. 146, 492) auxiliary (p. 148, 490) detail, and broken. Also, produce an example of a multi-sheet drawing. If you can accomplish all that with one part, that’s fine. Use rectangular graph paper and include all necessary views (at the maximum convenient scale in ‘blocks’ – not a measured scale). Also include projection and ‘fold’ lines (lightly), dimensions (p. 139, 500 and see rules in Figure 12.48), tolerances (see p 514 and demonstrate bilateral, unilateral, limit, geometric and decimal place tolerancing), title block (see Figure 12.35), border, and pertinent notes.

Advice:

1.      Keep it simple!

2.      To determine the maximum convenient scale, lay out a plan for your view(s) as though your object(s) was a simple rectangular block (see Figure 3.17 for iso or Figure 4.27 for ortho). You might even consider sketching a rough draft of each drawing to make sure you have accounted for dimensions etc.
