A metric dimension that is a whole number does not show a decimal point or a zero.

By adding dimensions to a technical drawing the drafter is providing information about the size and location of features of a part.

An extension line is a thin, dark, solid line that extends from a point on the drawing to which a dimension refers.

It is permissible to letter a dimension value over any line on the drawing.

Avoid dimensioning to hidden lines.

The engineering design process can address society's needs.

Technical drawings require use of standards to communicate worldwide.

Before other communication methods developed, people informed themselves through visual means, including pictures.

Life cycle design means that all aspects of a product are considered simultaneously.

Graphic representation has developed along two distinct lines, engineering and technical.

Traditional, sequential engineering design is a logical approach, but in practice it can often be wasteful.

Detail drawings are also called piece part drawings.

A skeleton assembly can be used to define locations of individual parts in an assembly.

Any principal view shows three of the four principal dimensions.

A plane surface that is parallel to a plane of projection appears on edge as a straight line.

First-angle projection is primarily used in Europe and Asia.

In offset sections, the bends in the cutting plane are typically shown in the sectional view.

Omit hidden lines from both halves of a half section whenever possible.

Quarter sections expose the interior of one half of the object and the exterior of the other half.

In oblique drawing, circles and angles perpendicular to the projection plane are true size and shape.

Drafters usually work alone in their cubical without any interaction with other drafters, designers, architects, or engineers.

Modern computer drafters must have a thorough understanding of industrial drafting standards.

In a welding symbol, the arrow points to the joint where the weld is to be made.

In a welding drawing, joints are all shown as they would appear before welding.

A polygon is a planar area that is enclosed by either angular or curved lines.

The most important rule in freehand sketching is to keep the sketch in proportion.

A freehand sketch should show attention to proportion, clarity, and correct line widths.

Sketches are usually made to a specific scale.

Hidden lines are usually included on assembly drawings.

Working drawings are not legal documents.

In assembly drawings, views should show how the parts fit together and suggest the function of the unit.

Patent drawings must be mechanically correct and constitute complete illustrations of every feature of the invention claimed.

Computation and design sketches may be considered to be technical drawings.

Solids are bounded by the surfaces that contain them.

A point represents a location in space and has no width, height, or depth.

Weldments are composed of a number of separate pieces fastened together as a unit.

Groove weld size is usually specified on the welding symbol.

Welding is often used for large structures that are difficult or impossible to fabricate entirely in a shop.

The symbol for the desired weld is attached to the reference line, or shank, of the arrow.

Defining the datum reference frame is necessary to apply GDT principles.

Nominal size is used for general identification and is usually expressed in decimals.

The preferred cutting plane line style is made up of equal dashes ending in arrowheads.

It is not acceptable to use the general-purpose symbol at different angles for different parts.

An architect's scale is divided into 10ths of an inch.

Prior to the development of computer aided drafting, drafters relied on drawing boards, paper, and pencils to create technical drawings.

A 15 degree line can be easily created by arranging both the 45 degree and 30/60 degree triangles.

Drawing scale refers only to the reduction of the size of a drawn object relative to the real object.

Multiview projection shows one or more necessary views of an object.

The ISO has its own system of preferred metric limits and fits.

Increased precision makes parts less expensive to manufacture.
