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
