79451. The maximum and minimum sizes of a feature are identified by a ________ tolerance.





79452. This is a line terminated by arrowheads, indicating the direction and extent of a dimension:





79453. In U.S. structural and architectural drafting, all dimensions of this length are usually expressed in feet and inches:





79454. The inch is the commonly used unit for most metric engineering drawings.



79455. Most mechanical drawings will include tolerance information in or near the drawing title block.



79456. When designing mechanical devices, the designer must consider what the allowable variation in size between mating parts can be.



79457. Fillet radii can be given in a general note.



79458. An external cylindrical shape is dimensioned where it appears circular.



79459. Where the decimal-inch dimension is used, a zero is not used before the decimal point of values less than 1.



79460. It is always acceptable to dimension to a hidden feature.



79461. When a finished part is measured, it may vary slightly from the exact dimension specified.



79462. Tolerance issues are primarily a concern in manufacturing rather than in the design and drafting process.



79463. Dimensions are given in the form of distances, angles, and notes only when using metric units.



79464. The nominal size of a feature is the exact measurement of the feature after the tolerance has been applied to it.



79465. Drawings are usually made to a scale, which is indicated in the title block.



79466. A set of two mutually perpendicular datum planes is required for coordinate dimensioning.



79467. Although an engineer has placed dimensions in specific locations the drafter has the freedom to arrange them as he deems necessary.



79468. Typically, all dimension values and notes are lettered horizontally and should read from the bottom of the sheet.



79469. A heavy straight line should be drawn under all dimension values that are to scale.



79470. By adding dimensions to a technical drawing the drafter is providing information about the size and location of features of a part.



79471. An extension line is a thin, dark, solid line that extends from a point on the drawing to which a dimension refers.



79472. It is permissible to letter a dimension value over any line on the drawing.



79473. It is more difficult to manufacture a part designed using two decimal places than the same part using four decimal places.



79474. In a group of parallel dimension lines, the dimension values should be staggered.



79475. When extension lines or centerlines cross visible object lines, gaps should not be left in the lines.



79476. The American Society of Mechanical Engineers provides a set of common standards used by industry for placement of dimensions.



79477. Longer dimension lines are nearest the object outline.



79478. A metric dimension that is a whole number does not show a decimal point or a zero.



79479. Dimension lines should not cross extension lines.



79480. Avoid dimensioning to hidden lines.



79481. The drafter should always try to dimension to the profile view of an object when possible.



79482. The condition of a part when it contains the least amount of material is referred to as ________.





79483. This is used to indicate that a surface is to be machined:





79484. The ________ tool on the Dimension tool bar places the length of an arch on a drawing.





79485. How can the drafter prevent AutoCAD from placing or stacking another center mark on a circle when adding a diameter dimension to it?




79486. In this type of dimensioning, allowance must be made for bends:





79487. The architectural and construction industries use the United States National CAD standard (NCS) system on many ________ projects.





79488. There should be a visible gap between the wall and the ________ line.





79489. Dimensions are used on the elevation plan to describe ________.





79490. The second line of dimensions out from the plan generally includes ________.





79491. The dimension text size is determined by what the architect deems necessary in ________.





79492. Tolerances in an architectural drawing are just as close as tolerances used in mechanical drawings.



79493. Drafters usually begin a set of dimensions from the inside edge of an exterior wall.



79494. The total dimension of the front side should match the total dimension of the back side.



79495. The text style used on an architectural drawing is determined by the drafter.



79496. The dimensioning standards used by a typical architectural firm were probably developed by the architects, designers, and drafters in the firm.



79497. Text and dimensions are aligned on the drawing so they can be easily read from the bottom and right side of the sheet.



79498. Dimensioning to the edges of doors and windows is the preferred method by most architectural drafters.



79499. Architectural dimensioning usually relies on tick marks or dots rather than arrow points.



79500. Minor errors in dimensioning on an architectural drawing can result in major construction problems on the job site.
