1

Drawings and specifications control details of:

• Product manufacture
• Assembly
• Maintenance

2

Technical drawings typically serve one of three purposes:

• Visualization
• Communication
• Documentation

3

Stages of the design process include:

• Problem identification
• Ideation
• Refinement/analysis
• Implementation/documentation

4

Concurrent engineering

A systematic approach that integrates the design and manufacture of products with the goal of optimizing the process

5

ANSI

American National Standards Institute

6

Perspective projection

The projectors come together at the station point

7

Parallel projection

The projectors are parallel

8

Orthographic projection

(right angle) projections have parallel projectors that are perpendicular to the plane of projection

9

Oblique projection

When projectors are parallel to each other but are at an angle other than 90 degrees to the plane of projection

10

Standard Sheet Sizes

A - 8.5x11
B - 11x17

11

Multiview projection

Shows one or more necessary views of an object
- There are two systems used to arrange the views:
• Third angle projection
• First angle projection

12

Edge

Formed where two surfaces intersect, edges are represented by visible or hidden lines

13

Vertex

Formed where three or more surfaces intersect, the end of an edge is a vertex

14

Points

represented by:
• The intersection of two lines
• A short crossbar on a line
• A small cross

15

One View Drawings

A single view supplemented by notes and dimensions can describe a simple object.

16

Oblique Sketches

Forty-five degrees is often chosen for the angle of receding lines

17

Drafting standards

-ANSI, ASME, ASEE, SAE
-American National Standard Drafting Manual
-ISO

18

5 step design process

-Identify the customer and /or the problem
-Generate concepts (solutions)
-Compromise solutions (order of selection)
-Models and prototypes (computer modeling and rapid prototyping)
-Production or working drawings

19

Two types of representations of graphics

Artistic
Technical
