Exam 24: Dual Dimensioning

Dual dimensioning is being used by many manufacturers during the transition period from the U.S. Customary (inch) system of measurement to the metric system.

____________________ dimensioning is the use of dimensions in both the U.S. Customary and SI systems of measurement on drawings.

Angle dimensions indicated in ____ are common to the inch and metric systems, and, therefore, are not normally shown as dual dimensioned.

It is standard practice to use "____" in a note to indicate diameter.

Dual-dimensioned prints are more costly to prepare; however, they permit greater flexibility in their application.

Dimensioning a drawing with ____________________ fractions has become standard practice.

The positioning arrangement selected for dual dimensioning is indicated by a(n) ____________________ on the drawing.

Countries that use the metric system normally prepare drawings using ____ projection.

The ____________________ is used in cases where dimensions are so large that it is impractical to show or perform the measurement in millimeters.

Manufacturers who market their products to international consumers only use SI dimensioning.

When the ____ method is used, the inch and metric dimensions are placed in specific locations with respect to one another.

The U.S. Customary unit of measurement may be given as a common or decimal fraction, but the common fraction is preferred.

The metric unit of measurement most commonly used on dual-dimensioned prints is the ____.

The ____ between inch and metric dimensions is determined by the number of decimal places to which each dimension is rounded off.

An alternative to the positioning and bracket methods for dual dimensioning is to provide a(n) ____________________ chart on the print.

When working with large dimensions, 18000 millimeters is best shown as ____ meters.
