Layouts and Lettering Questions

• 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:
• These units are based on inch-foot and yard measurements:
• There are two main types of projection:
• This is how axonometric, oblique, and perspective sketches show objects:
• When lettering a CAD drawing, for clarity you should limit the number of fonts to:
• The primary unit of measurement for engineering drawings and design in the mechanical industries is the:
• The meaning of each line on a technical drawing is indicated by its width and its particular line style.
• Multiview projection shows one or more necessary views of an object.
• Drawing scale refers only to the reduction of the size of a drawn object relative to the real object.
• Orthographic projections are a type of parallel projection.
• Axonometric, oblique, and perspective sketches show objects pictorially.
• Three systems are used to arrange orthographic views: first, second, and third angle projection.
• The same general concepts and drafting standards apply to CAD as to drawings created by hand.
• The main difference between a CAD drawing and a freehand sketch is in the appearance of lines.
• With regard to lettering, the shapes of letters are not described as part of drawing standards.
• Drawing units must be clearly stated on the drawing.
• In orthographic projection objects can be presented at true size or scaled at a proportion of their true size.
• Drawings that use U.S. customary units do not follow ANSI/ASME standards.
• Scale is stated as a ratio of the number of drawing units to the number of actual units.
• Orthographic projections have projectors that are parallel to the plane of projection.
