  12. To communicate non-graphic information. As a substitute for graphic information, in those instance where text can communicate the needed information more clearly and quickly. - shape - space between letters and words Legibility - size- line thickness Uniformity Text on Drawings Text on engineering drawing is used : Thus, it must be written with

  13. Dimension & Notes Title Block Notes Example Placement of the text on drawing-Standard

  14. Example Placement of the text on drawing-This course Offset-10 mm Drawings & Dimensions University of Palestine College of Engineering &Urban Planning First Level Drawing No.:(C1 or HW1) Scale:1:1 Dimensions in (mm) Submission Date : ?/?/2008 Student Name: Student ID: Class :

  15. Use only a vertical Gothic text style. Use a Gothic text style, either inclined or vertical. Use both capital and lower-case letters. Use all capital letters. Use 3 mm for most text height. Same. For letters in title block it is recommend to use 3~5 mm text height Space between lines of text is at least 1/3 of text height. N/A.Follows ANSI rule. Lettering Standard ANSI Standard This course

  16. Basic Strokes Straight Slanted Horizontal Curved Examples : Application of basic stroke 4 5 1 “I” letter “A” letter “B” letter 1 2 1 6 3 3 2

  17. Suggested Strokes Sequence Upper-case letters & Numerals Straight line letters Curved line letters Curved line letters & Numerals

  18. Suggested Strokes Sequence Lower-case letters The text’ s body height is about 2/3 the height of a capitalletter.

  31. J I R A P O N G Word Composition Look at the same word having different spacing between letters. A) Non-uniform spacing JIRAPONG B) Uniform spacing Which one is easier to read ?

  32. | | | \ ( ) | | | | Space between the letters depends on the contour of the letters at an adjacent side. Good spacing creates approximately equal backgroundarea between letters. Word Composition JIRAPONG Spacing \/ )( Contour General conclusions are:

  33. Space between Letters 1. Straight - Straight 3. Straight - Slant 2. Straight - Curve 4. Curve - Curve

  34. slant slant slant straight Space between Letters 5. Curve - Slant 6. Slant - Slant 7. The letter “L” and “T” ≡ ≡

  35. Example : Good and Poor Lettering GOOD Not uniform in style. Not uniform in height. Not uniformly vertical or inclined. Not uniform in thickness of stroke. Area between letters not uniform. Area between words not uniform.

  36. Sentence Composition Leave the space between words equal to the spacerequires for writing a letter “O”. Example O ALL DIMENSIONS O IN O ARE MILLIMETERS UNLESS O SPECIFIED. O OTHERWISE
