,T/F: Dimensioning and tolerancing shall be complete so there is a full understanding of the
characteristics of most features. - ANS False, there must be full understanding of all features.
No ambiguity.
From the textbook 15.03...
T/F: Each necessary dimension of an end product shall be shown, no more dimensions than
those necessary for complete definition shall be given. - ANS True.
From the textbook 15.03...
T/F: The drawing should define a part, as well as specifying manufacturing methods. -
ANS False, manufacturing methods are not to be specified in engineering drawings.
From the textbook 15.03...
T/F: Dimensions should be shown in true profile views, and refer to visible outlines in an
arrangement that provides information for optimum readability. - ANS True.
From the textbook 15.04...
Define dimension. - ANS A numerical value expressed in appropriate units of measure and
used to define the size, location, geometric characteristic, or surface texture of a party or part
feature.
From the textbook 15.04...
Define arrowhead. - ANS A small triangle at the end of dimension line and leaders to indicate
the direction and extent of a dimension.
From the textbook 15.04...
Define dimension line. - ANS A thin, dark, solid line that terminates at each end with
arrowheads. The value of a dimension is typically shown in the center of the dimension line.

, Define extension line. - ANS A thin, dark, solid line extending from a point on an object
perpendicular to a dimension line. Used to indicate the extension of a surface or point to a
location preferably outside the part outline.
From the textbook 15.04...
Define leader. - ANS A thin, dark, solid line terminating with an arrowhead at one end and a
dimension, note or symbol at the other. Used to direct a dimension , note or symbol to the
intended place on the drawing.
From the textbook 15.05...
What is the contour rule? (contour dimensioning) - ANS - Each dimension should be placed in

What kind of dimensioning?
- All dimensions in a given direction originate from a base or datum.
- Frequently used for CNC machines that work from a rectangular coordinate system. -
ANS Baseline dimensioning.
