SLIDE 2

 Convey

information

 Aid in design

process

 Documentation

Purpose of a Drawing

SLIDE 3

 Working (design) sketch  Presentation figure  Engineering (shop) drawing

Types of Drawings

SLIDE 4

 Aid in conceptual design  Usually hand-drawn  Pertinent dimensions

included

Working Sketches

SLIDE 5

 Convey design concepts  May be hand drawn or

computer generated

 May be 2-D or 3-D  May display key dimensions  May display part labels and

ther text

Presentation Figures

SLIDE 6

 Intended to convey all information necessary to

manufacture a part or assembly

 Should include:

 One or more views of the part  Dimensions  Details and notes  Drawing and part information

Drawing name Date Draftsperson Units of measure Scale Quantity Material

Shop Drawings

SLIDE 8

SLIDE 9

 A drawing will contain at least one view of the part  Typically two or three views are shown  Views are usually 2-D views  A 3-D view (usually isometric) may be included for

conceptualization

 2-D views are usually orthographic (drawn at right

angles)

 Orthographic views are most commonly arranged

using Third Angle Projection

Handouts: Projection Block, Fold Example

Shop Drawings: Views

SLIDE 10

SLIDE 11

SLIDE 12

Shop Drawings: Line Styles

 Help to clarify views of a part  Differentiate between part and dimensions

SLIDE 13

Shop Drawings: Symbols

 Adds information to a dimension  Aids in describing a feature (such as a hole)

Common drawing symbols: R = radius Ø = diameter THRU = feature extends “through” the part DEEP = depth of a hole or feature

SLIDE 14

Shop Drawings: Basics

 The most important aspect of a drawing is clarity  Witness lines should extend to features  All features require an X and a Y dimension  Holes are dimensioned to center  Dimensions and details should not reference hidden

features

 Leave gaps between features and witness lines
