  1. A system of dimensioning which requires all numerals, figures, and notes to be aligned with the dimension lines so that they may be read from the bottom (for horizontal dimensions) and from the right side (for vertical dimensions).
    aligned dimension
  2. The tightest possible fit between two mating parts.
  3. A private, non-profit organization that coordinates the development and use of a voluntary consensus standards in the United States.
    American National Standards Institute (ANSI)
  4. A professional engineering organization that is known for setting codes and standards for mechanical devices in the United States.
    American Society of Mechanical Engineers (ASME)
  5. The understanding of the consumer group for which the design is targeted. This would include the audiences, demographics, physical location, amount of time available to view the design, and interest in the subject matter.
    audience analysis
  6. A view that is used to show features that are located on an inclined surface in true size and shape.
    auxiliary view
  7. System of dimensioning in which all dimensions are placed from a datum and not from feature to feature. Also referred to as Datum Dimensioning.
    baseline dimensioning
  8. A circle with a single number connected to an assembly component with a leader line to refer to parts.
  9. A tolerance in which variation is permitted in both directions from the specified dimension.
    bilateral tolerance
  10. A hole that does not go completely through the workpiece.
    blind hole
  11. A section of an object broken away to reveal an interior feature for a sectional drawing.
    broken-out section
  12. Also known as point-to-point dimensioning where dimensions are established from one point to the next.
    chain dimensioning
  13. Limits the size of mating parts so that a clearance always results when mating parts are assembled.
    clearance fit
  14. A cylindrical recess around a hole, usually to receive a bolt head or nut.
  15. A conical-shaped recess around a hole, often used to receive a tapered screw.
  16. A line drawn on a view where a cut was made in order to define the location of the imaginary section plane.
    cutting plane line
  17. A theoretically exact point, axis, or plane derived from the true geometric counterpart of a specific datum feature. The origin from which the location, or geometric characteristic of a part feature, is established.
  18. A dimensioning system where each dimension originates from a common surface, plane, or axis. Also known as baseline dimensioning.
    datum dimensioning
  19. A tool used to compare design solutions against one another, using specific criteria.
    decision matrix
  20. A dimensioned, working drawing of a single part. Also referred to as part drawing.
    detail drawing
  21. A view that is used to show a magnified view of features that are too small to adequately specify in another view.
    detail view
  22. Where alternate units are displayed within the same dimension.
    dual dimensions
  23. An inside radius between two intersecting planes.
  24. To show lines or objects shorter than their true size. Foreshortened lines are not perpendicular to the line of sight.
  25. A sectional drawing based on a cutting plane line that extends completely through an object.
    full section
  26. A sectional drawing based on a cutting plane line that cuts through one-quarter of an object. A half section reveals half of the interior and half of the exterior.
    half section
  27. Notes placed separate form the views; relate to the entire drawing.
    general notes
  28. The amount of overlap that one part has with another when assembled.
  29. Limits the size of mating parts so that an interference always results when mating parts are assembled.
    interference fit
  30. This is a worldwide organization that creates engineering standards.
    International Organization for Standardization (IOS)
  31. The smallest size limit of an external feature and the largest size limit of an internal feature.
    least material condition (LMC)
  32. The largest and smallest possible boundaries to which a feature may be made as related to the tolerance of the dimension.
    limit dimensions
  33. Connected to specific features on the views of the drawing. Also known as annotations.
    local notes
  34. A location dimension that defines the relationship of features of an object.
    location dimension
  35. The activity of gathering information about consumers' needs and preferences.
    market research
  36. The largest size limit of an external feature and the smallest size limit of an internal feature.
    maximum material condition (MMC)
  37. The designation of the size established for a commercial product.
    nominal size
  38. A drawing that contains all the information for making one part of the design.
    part drawing
  39. A list of materials or parts specified for a project. ALso referred to as a bill of materials or BOM.
    parts list
  40. A distance of uniform measure determined at a point on one unit to the same corresponding point on the next unit; used in threads, springs, and other machine parts.
  41. A dimension, usually without a tolerance, used for information purposes only. A reference is a repeat of a given dimension or established from other values shown on a drawing. Reference dimensions are enclosed in ( ) on the drawing.
    reference dimension
