Engineering Drawing The words of the language, as they are written or spoken, do not seem to play any role in my mechanism of thought. The psychical entities which seem to serve as elements in thought are certain signs and more or less clear images which can be “voluntarily” reproduced and combined--this combinatory play seems to be the essential feature in productive thought before there is any connection with logical construction in words or other kinds of signs which are communicated to others   --Albert Einstein Contents
1. Try to write a  description  of this object. 2. Test your written description by having someone attempt   to  make a sketch  or  visualize   from your description. Effectiveness of Graphic Language The word language is  inadequate  for describing the  size ,  shape   and  features   completely as well as concisely. You can easily understand that …
Graphic Language in Engineering Drawing “ Engineering drawing”  or  “blueprint”  uses  l ines   to represent the  features  of an object. Features   of an object are  surface  (include  plane ) and edge . Surface Edge
A drawing can be created in 3 ways Ways to Create an Engineering Drawing ,[object Object],[object Object],[object Object]
Example Create a Drawing :  Freehand sketch Pictorial sketch Orthographic sketch The lines are drawn using only pencil and erasers on a blank or grid paper.
Example Create a Drawing :  Using instruments Drawing instruments are used to draw straight lines, circles, and curves  concisely  and  accurately .  Drawings are usually  made to scale .
Example Create a Drawing :  Using a computer 2D drawing Solid modeling Computer aided drafting (CAD) software is used.
Elements of a Drawing A clear and precise engineering drawing requires both  graphics  and  word  languages. Graphics language Describe a shape (mainly). Word language Describe an exact size, location and specification of the object.
Text on drawings :  Example General notes Title block Dimensions & Notes
Knowledge and Skills Require Graphics language Word language Visualization  is the ability to  mentally  picture things that do not exists. Engineering Drawing Dimensions & Notes Visualization Using line types Geometric construction Projection method Contents

Definition and Necessity Drawing standards are  set of rules  that govern how technical drawings are represented. Drawing standards are used so that drawings  convey the same meaning   to everyone who reads them.

Drawing  Scales :  Definition Drawing Actual Length, size 1 2 : Scale  is a ratio between the linear dimension of a drawn representation of an object and the actual object.
SCALE 1:1 for full size SCALE  X :1 (X > 1) for an  enlargement   scales SCALE 1: X (X > 1)  for a  reduction   scales Drawing  Scales :  Designation Designation of a scale consists of the word “ SCALE ”  followed by the  indication of its ratio , as follows Drawing scale is commonly found in a title block.
Drawing  Scales :  Notes Dimension numbers  shown in the drawing represent the “ true size ” of an object and they are  independent  of the drawing scale used.
Drawing  Scales :  Standard scale Standard  reducing  scales are 1:2, 1:5, 1:10, 1:20, 1:50, 1:100 Standard  enlarging  scales are 2:1, 5:1, 10:1, 20:1, 50:1, 100:1
Drawing Standard Lettering Drawing standard Contents
- Size (or text height) - line thickness ,[object Object],[object Object],[object Object],Recommendation Legibility Uniformity Examples GOOD Not uniform in style. Not uniform in height. Not uniformly vertical. Not uniform in thickness of stroke. Inappropriate space between letters Text’s style on the drawing must have the following 2 properties
Style  (this course) Gothic  vertical  style. Begin the sentence, phrase or word with a capital letter. Text height 2~3 mm.  Space between lines of text is about of text height. Height of the lower-case letter is about  2/3  of that of a capital letter.

DRAWING Word  Composition Non-uniform spacing Uniform spacing D R A W I N G Space between the letters depends on the adjacent contour of the letters. Word having non-uniform spacing is more readable.
Word  Composition Contour DRAWING Adjacent contour can be 1. straight-straight   :  II, IN, IM, IP  etc. 2. straight-curve  (or curve-straight)  :  IO, QR  etc. 3. straight-slant  (or slant-straight)   :  IV, IW  etc. 4. curve-curve   :  OO, OG  etc. 5. slant-curve  (or curve-slant)   :  VO, WG, VC  etc. 6. slant-slant   :  VW, VX  etc. Spacing Contour can be denoted as “ straight ”, “ slant ” and “ curve ”.
Leave the space between words equal to the space requires for writing a letter “O”.  Example Sentence  Composition ALL DIMENSIONS ARE IN MILLIMETERS O O O O UNLESS OTHERWISE SPECIFIED. O

Engineering Drawing: Chapter 01 introduction

  • 2. Contents Drawing standards Engineering drawing Drawing sheet Scale Lettering Line types
  • 3. Engineering Drawing The words of the language, as they are written or spoken, do not seem to play any role in my mechanism of thought. The psychical entities which seem to serve as elements in thought are certain signs and more or less clear images which can be “voluntarily” reproduced and combined--this combinatory play seems to be the essential feature in productive thought before there is any connection with logical construction in words or other kinds of signs which are communicated to others --Albert Einstein Contents
  • 4. 1. Try to write a description of this object. 2. Test your written description by having someone attempt to make a sketch or visualize from your description. Effectiveness of Graphic Language The word language is inadequate for describing the size , shape and features completely as well as concisely. You can easily understand that …
  • 5. Graphic Language in Engineering Drawing “ Engineering drawing” or “blueprint” uses l ines to represent the features of an object. Features of an object are surface (include plane ) and edge . Surface Edge

  • 7. Example Create a Drawing : Freehand sketch Pictorial sketch Orthographic sketch The lines are drawn using only pencil and erasers on a blank or grid paper.
  • 8. Example Create a Drawing : Using instruments Drawing instruments are used to draw straight lines, circles, and curves concisely and accurately . Drawings are usually made to scale .
  • 9. Example Create a Drawing : Using a computer 2D drawing Solid modeling Computer aided drafting (CAD) software is used.
  • 10. Elements of a Drawing A clear and precise engineering drawing requires both graphics and word languages. Graphics language Describe a shape (mainly). Word language Describe an exact size, location and specification of the object.
  • 11. Text on drawings : Example General notes Title block Dimensions & Notes
  • 12. Knowledge and Skills Require Graphics language Word language Visualization is the ability to mentally picture things that do not exists. Engineering Drawing Dimensions & Notes Visualization Using line types Geometric construction Projection method Contents

  • 14. Definition and Necessity Drawing standards are set of rules that govern how technical drawings are represented. Drawing standards are used so that drawings convey the same meaning to everyone who reads them.

  • 21. Drawing Scales : Definition Drawing Actual Length, size 1 2 : Scale is a ratio between the linear dimension of a drawn representation of an object and the actual object.
  • 22. SCALE 1:1 for full size SCALE X :1 (X > 1) for an enlargement scales SCALE 1: X (X > 1) for a reduction scales Drawing Scales : Designation Designation of a scale consists of the word “ SCALE ” followed by the indication of its ratio , as follows Drawing scale is commonly found in a title block.
  • 23. Drawing Scales : Notes Dimension numbers shown in the drawing represent the “ true size ” of an object and they are independent of the drawing scale used.
  • 24. Drawing Scales : Standard scale Standard reducing scales are 1:2, 1:5, 1:10, 1:20, 1:50, 1:100 Standard enlarging scales are 2:1, 5:1, 10:1, 20:1, 50:1, 100:1
