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 (b)
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.
