DIMENSIONING AND TOLERANCING

Only dimensions needed for complete definition should be given

• TRUE
• FALSE

It is allowed to identify (as nonmandatory) certain processing dimensions that provide for finish allowance, shrink allowance, and other requirements, provided the final dimensions are given on the drawing.

• TRUE
• FALSE

Each dimension has a tolerance except for dimensions specifically identified as reference, maximum, minimum, or stock.

• TRUE
• FALSE

Basic dimension values in inch dimensioning have the same number of decimal places as their associated tolerance.

• TRUE
• FALSE

Unilateral inch tolerances use the + and – symbol and the 0 value has the same number of decimal places as the value that is greater or less than 0.

• TRUE
• FALSE

A 90° basic angle applies where centerlines of features are located by basic dimensions and no angle is specified.

• TRUE
• FALSE

Unless otherwise specified, all geometric tolerances apply for full depth, length, and width of the feature.

• TRUE
• FALSE

Dimensions should be selected and arranged to suit the function and mating relationship of a part.

• TRUE
• FALSE

A zero precedes a decimal inch that is less than one.

• TRUE
• FALSE

The tolerance must be applied directly to the dimension, and cannot be indicated by a general note.

• TRUE
• FALSE
