Personal or cultural expression in design is often referred to as functional design.

Visible lines always take precedence over hidden lines or centerlines.

A total of three principal views are arranged in a standard way.

Any object can be viewed from six mutually perpendicular views.

A plane surface always projects either on edge or as a surface in any view.

Height is shown in the left-side, top, right-side, and bottom views.

The inch is the commonly used unit for most metric engineering drawings.

Most mechanical drawings will include tolerance information in or near the drawing title block.

When designing mechanical devices, the designer must consider what the allowable variation in size between mating parts can be.

Fillet radii can be given in a general note.

An external cylindrical shape is dimensioned where it appears circular.

Type of weld is typically not specified on the welding symbol.

Welding is often more expensive when only one or a few identical parts are required.

A spot weld is a type of resistance weld.

Welding templates can simplify drawing welding symbols by hand.

Leonardo da Vinci did not rely on technical drawings for his many inventions.

As you sketch a solid object, you should maintain at least two different viewpoints.

If the faces of a solid are equal regular polygons, it is a regular polyhedron.

All professional engineers are good CAD drafters.

The end of an edge is a vertex.

An electronics drafter is typically involved in the development of wiring schematics for large commercial buildings.

A detail drawing of a part is intended to provide the necessary information needed to fabricate that part.

Mechanical designers can expect to make several revisions to a design before it is finalized.

The mechanical engineering industry relies on complex mechanical drawings that are often referred to as working drawings.

Frequently a single view supplemented by notes and dimensions can describe a simple object.

An architect does not need to know how many people are going to live in a house before he begins his design.

If an edge is perpendicular to a plane of projection, it appears as a point.

In cabinet oblique projection, receding lines are drawn at full scale.

Process piping drafters would likely produce drawings for a water treatment plant.

Points may be represented by simple dots.

The depth dimensions in the top and side views do not necessarily correspond.

Width is shown in the rear, top, front, and bottom views.

The procedure for designing products typically follows a process.

Product design often involves preparing analytical and physical models of the product.

In the design process, it is generally never necessary to return to a previous stage and repeat the process.

Using drawings to represent the design of objects to be built or constructed is a relatively new concept.

If an angle is in an inclined plane, it may be projected either larger or smaller than the true angle depending on its position.

Drafters do not need to worry about the number of decimal places used on dimensioning a technical drawing.

An assembly drawing is intended to illustrate a single mechanical part.

Usually screws, bolts, shafts, tubes, and other elongated parts are drawn in a vertical position in the front view.

In orthographic views, dashed lines represent features that would be hidden behind other surfaces.

Drawings are two-dimensional representations of objects that allow you to record sizes and shapes precisely.

Assembly drawings are usually not dimensioned.

When multiple detail drawings are shown on one sheet, it is not always necessary to identify each part.

In assembly sections, bolts, nuts, and keys are typically left unsectioned.

A normal surface is perpendicular to a plane of projection.

In a group of parallel dimension lines, the dimension values should be staggered.

The drafter should always try to dimension to the profile view of an object when possible.

It is more difficult to manufacture a part designed using two decimal places than the same part using four decimal places.

When extension lines or centerlines cross visible object lines, gaps should not be left in the lines.
