    Scaling vs. Dimensioning

    Drawings can be different scales, but dimensions are ALWAYS at FULL

    scale

    Standards of Measurement:1. Inch System

    1. When all of the dimensions are expressed ininches, do not use inch mark () or theabbreviation for inches (in.)

    2. values less that one inch should NOT be precededwith a zero.

    2. Metric (ISO)1. For metric drawings, omit the use of the

    millimeter (mm) notation following the numeral,as millimeters are the default units.

    2. Values less than 1 mm SHOULD BE preceded witha zero

    THE BASIC CONCEPT

    Dimensioning is accomplished by adding size and

    location information necessary to manufacture

    the object.

    General Guideline

    To think that you would make an object and dimension it in

    the most useful way. Put in exactly as many dimensions as are necessary for the

    craftsperson to make it -no more, no less.

    Do not put in redundant dimensions.

    It is often better to measure from one end to various points.This gives the dimensions a reference standard. Repeatedlymeasuring from one point to another will lead toinaccuracies.

    It is helpful to choose the placement of the dimension in theorder in which a machinist would create the part. Thisconvention may take some experience.

    Dimensioning Rules Basics 11. Dimension lines should never cross.

    2. Dimension lines should NOT coincide or continue any line of the drawing.

    3. Dimension lines should be lined up and grouped together.4. Extension lines may cross each other and over other lines on the part

    5. Extension lines can be shared, and broken.

    6. Dimension lines and extension lines are usually drawn at 90 degree

    angles7. Centerlines can be used as a measurement location, but not as extension

    lines.

    8. Always place the first row of dimensions a minimum distance of3 text

    heights away from the edge of the part. Additional stacks can be a

    minimum of2 text heights away from each other.

    9. The overall dimension should always be given. It should be placed

    outside of smaller dimensions and be the furthest dimension from the

    part.

    Dimensioning Rules Basics 2

    10. If the measurement on the drawing is less than 5mm or 0.20

    inches, then the arrows are placed outside the extension lines.11. Avoid placing any dimensions on the part (inside the view)

    unless there is no other option.

    12. Avoid dimensioning to hidden features

    13. Always place the dimension where the characteristic shape is

    shown in the most descriptive view. (This means dont place adimension on object lines making a T joint.)

    14. Keep dimensions between the views whenever possible

    15. Do not duplicate dimensions and avoid using unnecessary or

    superfluous dimensions

    16. Stagger horizontal dimensions to avoid contact or crowding of

    values.

    Dimensioning Rules: Curved Features

    17. Place the R in front of radius dimensions and, the diametersymbol () in front of diameter dimensions.

    18. Always dimension holes in their circular view by stating thediameter of drilled holes.

    19. Dimension cylindrical objects as diameters in their rectangularview

    20. Dimension rounded corners and arc features as radii wherethey appear in their rounded views.

    21. Leaders start at the beginning or end of a note. Point them

    toward the center of circular features that they are specifying.

    22. Dimension angles by specifying a) the angle in degrees and b)

    a linear dimension.

    23. Specify the hole depth of special features such as

    countersinking with a note following the dimension.

    Dimensioning Rules: Advanced

    24. If the same value is repeated many times, then

    use a general note for the features.

    25. Dimension repetitive features using the symbol

    (x) [multiplication]26. The origin for baseline or ordinate dimensions

    used as a datum should be extended from afinished edge of the part.

    27. Conserve space and time by using abbreviationsand standardized symbols whenever possible.

    28. Reference dimensions should be placed inparentheses or should include the abbreviationREF.
