An internal thread is a thread on the outside of a member.

The root is the top surface joining the two sides of a thread.

Any inclined surface can be shown in true shape when the appropriate auxiliary view is used.

Auxiliary views of 3-dimensional parts can be easily created with AutoCAD.

Warped surfaces cannot be unrolled or unfolded to lie flat.

Generally, hidden lines should be omitted in auxiliary views.

Revolution is a method of determining the true length and true size of inclined and oblique lines and planes.

An auxiliary view is an orthographic view that is not a standard projection.

The intersection of a plane and a circular cylinder is called a conic section.

Reference lines are always at right angles to the projection lines between the views.

A primary auxiliary view does not need to be parallel to the associated inclined plane.

A reference plane appears as a line in an adjacent view.

An auxiliary view is used on technical drawings to project features on an inclined plane away from one of the primary views in such a way that features such as holes appear correctly.

An intersection drawing is a flat representation or pattern that, when folded together, creates a 3D object.

A Secondary Auxiliary view is a projection from the first auxiliary view.

Springs may be classified as either helical springs or flat springs.

Pitch is equal to 12 divided by the number of threads per inch.

Rivets are not considered permanent fasteners.

A machine pin is a mechanical device designed to store energy when deflected and to return the equivalent amount of energy when released.

Tap drill depth does not include the cone point of the drill.

Another method used to setup an auxiliary view is to align the UCS with the inclined plane.

Measurements are always made at right angles to the reference lines or parallel to the projection lines.

A double-curved surface is generated by a curved line and has straight-line elements.

The American Society of Mechanical Engineers provides a set of standards for using auxiliary views.

If an auxiliary view is symmetrical, and to save space or time, a half auxiliary view may be drawn.

From primary auxiliary views, a secondary auxiliary view can be drawn.

The center line of a hidden cylinder feature appearing in the front view should line up with the center mark in the corresponding circle which appears in the auxiliary view.

A single-curved surface is a developable ruled surface that can be unrolled to coincide with a cylinder.

Laminated object manufacturing produces solid parts from sheets of material such as paper or vinyl.

Fused deposition modeling systems use molten plastic deposited in layers corresponding to cross sections on the part.

Cost and availability of raw and processed materials and manufactured components are major concerns in manufacturing.

Nanotechnology and nanofabrication are terms used to describe extremely large-scale operations.

A partial auxiliary view usually shows only features on the ________ of the inclined line and not any projection of other planes.

A partial auxiliary view is used to show only the ________ in the auxiliary view.

This type of surface may be a plane, a single curved surface, or a warped surface:

In this type of view, the cutting plane line indicates both the location of the cutting plane and the direction of sight:

The principle views associated with orthographic projection are ________.

This is the most common application for developments and intersections:

This type of auxiliary view is projected onto a plane that is perpendicular to one of the principal planes of projection:

The architectural and construction industries use the United States National CAD standard (NCS) system on many ________ projects.

There should be a visible gap between the wall and the ________ line.

Text and dimensions are aligned on the drawing so they can be easily read from the bottom and right side of the sheet.

Dimensioning to the edges of doors and windows is the preferred method by most architectural drafters.

Architectural dimensioning usually relies on tick marks or dots rather than arrow points.

Minor errors in dimensioning on an architectural drawing can result in major construction problems on the job site.

Architectural drafters are usually expected to place dimensions to the CAD standards established by the firm.

The major diameter is the largest diameter of a screw thread.

Concurrent engineering involves all disciplines in the early design stages.

Selective laser sintering apparatus uses laser-hardened resins to form models.

Rapid prototyping costs about the same, but takes less time than traditional prototyping.
