  6. Dimensioning Revisited Chapter 9

  7. Understanding Dimensioning • Drawings for products must be dimensioned so that production personnel all over the world can make mating parts that will fit properly when assembled or when used to replace parts • Dimensions are given in the form of distances, angles, and notes regardless of the dimensioning units being used

  8. Aspects of Good Dimensioning • The ability to create good dimensions requires: • Technique of dimensioning • Placement of dimensions manufacturing, measurement, inspection, functioning. • Choice of dimensions

  9. Using Dimension and Extension Lines

  10. Using Dimension and Extension Lines

  11. Using Dimension and Extension Lines • Dimensions should be lined up and grouped together as much as possible

  12. Using Dimension and Extension Lines • When extension lines or center lines cross visible object lines, gaps should not be left in the lines

  13. Leaders • A leader is a thin solid line directing attention to a note or dimension and starting with an arrowhead or dot • Leaders should be at an angle of 30-60˚

  14. Placing Dimensions • Never letter a dimension value over any line on the drawing • In a group of parallel dimension lines, the dimension values should be staggered • Do not crowd dimension figures into limited spaces making them illegible

  15. Placing Dimensions • Place dimensions between views when possible, but only attached to a single view • Dimensions should not be placed on a view unless doing so promotes the clarity of the drawing

  16. Placing Dimensions • When a dimension must be placed in a hatched area or on the view, leave an opening in the hatching or a break in the lines for the dimension value

  17. Placing Dimensions • Avoid dimensioning to hidden lines • Do not attach dimensions to visible lines where the meaning is not clear • Notes for holes are usually placed where you see the circular shape of the hole • An external cylindrical shape is dimensioned where it appears rectangular

  18. Placing Dimensions • Give dimensions where the contours of the object are defined

  19. Superfluous Dimensions • All necessary dimensions must be shown but avoid giving unnecessary dimensions • Do not repeat dimensions on the same view or on different views, or give the same information two different ways

  20. Dimensioning Angles • You should dimension angles by specifying the angle in degrees and a linear dimension

  21. Dimensioning Arcs • A circular arc is dimensioned in the view where you see its true shape by giving the value for its radius preceded by the abbreviation R

  22. Fillets and Rounds • Individual fillets and rounds are dimensioned like other arcs • If there are only a few and they are obviously the same size, giving one typical radius is preferred • Fillets radii can also be given in a general note

  23. Size Dimensions: Holes

  24. Dimension Symbols

  25. Dimensioning Rounded-end Shapes

  26. Dimensioning Threads

  27. Dimensioning Chamfers

  28. Location Dimensions

  29. Location Dimensions

  30. Mating Dimensions

  31. Which is the mating dimension in figure (a) Which is the mating dimension in figure (b)

  32. Notes • It is usually necessary to supplement the direct dimensions with notes • Notes should be worded to allow only one interpretation • Notes should be lettered horizontally

  33. Tabular Dimensions Several parts with Similar features Different dimensions.
