Blueprint quiz 1-6 true and false

A chord is always larger than the diameter.

False

A runout is formed when a sharp edge of a prism intersects at an angle with a cylindrical surface.

False

A surface that appears true size and shape in two of the three regular views is called a normal surface.

False

An isosceles triangle has three 60° angles.

False

Another name for the aligned section is the offset section.

False

CAD models are classified as solid models or hollow models.

False

Different materials, such as steel, rubber, or cast iron, are indicated with different angles for the hatch pattern.

False

Drafters and print readers must possess the same level of understanding about creating prints.

False

Each type of line in the standards has one, and only one, option for its appearance.

False

Electronic documents can be viewed on a computer screen in 2D format, with zoom and pan, but 3D "turn-and-tilt" capabilities (dynamic rotating) are not available.

False

If two circles share only two points, they are described as being tangent with each other.

False

In a CAD environment, copies must be made with a plotter, not a printer.

False

In engineering drawings and industrial prints, the text and numeric information is referred to as printing.

False

In section views, the rib rule specifies that "ribs must always be sectioned with an offset plane."

False

It is a future goal of ASME standards to set forth guidelines for how 3D model geometry information can be used to communicate some of the information currently found on prints.

False

Metric sheet sizes are identified as A0, B1, C2, D3, and E4.

False

On an international scale, some companies use first-, second-, or third-angle projection, while in the United States fourth-angle projection is used.

False

One disadvantage of larger prints is that they require large, flat-file drawers for storage.

False

One principle of multiview projection is that every surface shows up in one of two ways: as true size and shape or as a line.

False

Paths of motion can be indicated on a print with the chain line.

False

Phantom lines are used to "shade" the area of material cut by the cutting plane.

False

Section view principles only apply to the six normal views, not to auxiliary views.

False

Standards for sheet sizes, title blocks, and associated lists, both inch and metric, are covered in one ASME standard.

False

Text created by hand is identified as single-stroke Gothic because the letters are to be created with one continuous stroke.

False

The American Society of Manufacturing Enterprises oversees and publishes standards for engineering drawings.

False

The latest standards set forth the appearance of each line available for industrial prints, including exact line thickness and exact dash and space lengths.

False

The portion of the standards entitled "specifications" deals with how to properly chart a list of parts for an assembly or subassembly.

False

The scale area of the title block indicates the scale of the drawing as real = paper.

False

The size area of the title block is used to indicate the overall sizes of the part.

False

The text found on prints is most commonly done in lowercase letters, as that takes up less space.

False

There usually is not room for descriptive modifiers of parts to be placed in the title block.

False

A basic orthographic projection of an object creates six normal views.

True

A projected view is two dimensional, even though the object is three dimensional.

True

A quadrilateral with no sides parallel is called a trapezium.

True

A removed section view could be a partial section view and not include the entire object.

True

A revolved section has a cutting plane slicing through a feature, but the section view itself is "rotated" 90° directly on the regular view.

True

A screw thread is in the form of a helix on the surface of a cylinder.

True

A section view is created by passing an imaginary plane through an object and removing part of the object.

True

A seven-sided polygon is called a heptagon.

True

Additive manufacturing processes build a model by adding material layer by layer.

True

All surfaces appear in every view of a multiview drawing, even if only as a line or a hidden line.

True

An inclined surface appears as a foreshortened shape in two of the three regular views.

True

Before computer-based documents changed the way drafters work, it was common to keep one original drawing in a file-drawer system and prints were created from the original as needed.

True

Border lines are technically not in the alphabet of lines.

True

Engineering A-size paper is 8.5² ´ 11², while architectural A-size paper is 9² ´ 12².

True

For an offset section, the "bends" are not actually shown in the section view, but rather only on the cutting-plane line.

True

For companies with an international presence or product line, ISO standards may be an appropriate source for standardization practices.

True

For prints created with first-angle projection techniques, the views appear the same, but not in the same arrangement.

True

In dimensioning, a leader is used to point to a feature with a local note.

True

In recent years, the standards have only recommended two line weights: thick and thin.

True

In the United States, the decimal-inch system is still predominant, especially with respect to paper sheet sizes.

True

It is important to study the title block early and often in the process of interpreting the full scope of the product or part.

True

Orthographic projection is the foundational system behind multiview drawings.

True

Some textbooks and CAD software programs refer to extension lines as witness lines, although that term is not used in the standards.

True

Sometimes, hidden lines are omitted on complex views when the drawing is clear without them.

True

Splines are somewhat freeform, curvy lines that are sometimes referred to as B-splines or Bézier curves.

True

The early method of creating prints was a wet process that resulted in white lines on a blue background, thus the name blueprint.

True

Two cylinders are defined as coaxial if they share a common center axis.

True

Visualizing objects on a print requires an understanding of the principles of projection.

True

When sectioning an assembly of several parts, it is common to leave the main shaft and the bodies of fasteners uncut by the cutting plane.

True
