79601. This type of drawing is created to calculate areas, locate property lines, and locate building projects and facilities:

79602. These are accurately drawn maps of cities and towns showing property lines and other features that control property ownership:

79603. A plat is a map of a small area that is plotted from a land survey.

79604. Hydrographic maps convey information concerning bodies of water.

79605. Engineering maps are typically made for special projects as an aid to locations and construction.

79606. Differential leveling is the process of using a level and a telescope to determine differences in elevation.

79607. A plat typically shows elevations.

79608. Commonly, elevations are referenced to mean sea level.

79609. Monuments marking surveying points are typically not intended to be permanent.

79610. Hatchures are short, parallel, or slightly divergent lines drawn in the direction of a slope.

79611. A contour interval is the horizontal distance between horizontal planes passing through successive contours.

79612. Before highway construction begins, it is usually necessary to plan the horizontal and vertical location and alignments.

79613. An elevation drawing consists of a series of intersecting straight lines of accurately measured lengths.

79614. Topography is the science or art of map making.

79615. Nautical maps and charts show prominent landmarks used for air navigators.

79616. The bearing of a line is its angle from magnetic south.

79617. On a single contour line, all points have the same elevation.

79618. These maps are used in planning installations of trees, shrubbery, drives, and other garden features:

79619. These are special installations of stone or concrete marking the locations of points accurately determined by precise surveying:

79620. These are vertical distances above a common datum, reference plane, or point:

79621. These are lines drawn on a map to locate, in the plan view, points of equal ground elevation:

79622. These maps are used to plan construction projects that locate construction features so they fit the topography of the area:

79623. There are two main types of projection:

79624. In orthographic projection objects can be presented at true size or scaled at a proportion of their true size.

79625. The same general concepts and drafting standards apply to CAD as to drawings created by hand.

79626. The meaning of each line on a technical drawing is indicated by its width and its particular line style.

79627. Orthographic projections are a type of parallel projection.

79628. Drawings that use U.S. customary units do not follow ANSI/ASME standards.

79629. The main difference between a CAD drawing and a freehand sketch is in the appearance of lines.

79630. With regard to lettering, the shapes of letters are not described as part of drawing standards.

79631. Scale is stated as a ratio of the number of drawing units to the number of actual units.

79632. Axonometric, oblique, and perspective sketches show objects pictorially.

79633. Drawing units must be clearly stated on the drawing.

79634. Drawing scale refers only to the reduction of the size of a drawn object relative to the real object.

79635. The bacteria grows in the baby intestine and prevent harmful bacteria such as E-coil from growing and causing diarrhea the bacteria called

79636. Multiview projection shows one or more necessary views of an object.

79637. Three systems are used to arrange orthographic views: first, second, and third angle projection.

79638. When lettering a CAD drawing, for clarity you should limit the number of fonts to:

79639. The primary unit of measurement for engineering drawings and design in the mechanical industries is the:

79640. These units are based on inch-foot and yard measurements:

79641. This is how axonometric, oblique, and perspective sketches show objects:

79642. This type of projection is when projectors are parallel to each other, but are at an angle other than 90 degrees to the plane of projection:

79643. Approximately this much of the cost of product development and manufacture is determined at the design stage:

79644. This is a solid shape that fits inside the mold and forms a hole in a cooled cast metal or molten plastic object:

79645. In net-shape manufacturing, the part is made as close to the final specifications as possible to cut down on the cost of finishing operations.

79646. Laminated object manufacturing produces solid parts from sheets of material such as paper or vinyl.

79647. Fused deposition modeling systems use molten plastic deposited in layers corresponding to cross sections on the part.

79648. Cost and availability of raw and processed materials and manufactured components are major concerns in manufacturing.

79649. Nanotechnology and nanofabrication are terms used to describe extremely large-scale operations.

79650. Computer-aided manufacturing typically involves all phases of manufacturing.
