Technical Sketching Questions

• In cabinet oblique projection, receding lines are drawn at full scale.
• Frequently a single view supplemented by notes and dimensions can describe a simple object.
• Drafters usually work alone in their cubical without any interaction with other drafters, designers, architects, or engineers.
• It is much easier for a drafter to use a CAD system rather than traditional board drawing because corrections are much easier to make.
• In a pictorial sketch you can see the width, height, and depth of an object in a single view.
• A set of written specifications is often included in a set of technical drawings.
• As you sketch a solid object, you should maintain at least two different viewpoints.
• A freehand sketch should show attention to proportion, clarity, and correct line widths.
• Sketches are usually made to a specific scale.
• If the faces of a solid are equal regular polygons, it is a regular polyhedron.
• Perspective pictorials approximate the view produced by the human eye.
• In cavalier oblique projection, the depth is represented at half scale.
• In oblique drawing, circles and angles perpendicular to the projection plane are true size and shape.
• Modern computer drafters must have a thorough understanding of industrial drafting standards.
• A point represents a location in space and has no width, height, or depth.
• The most important rule in freehand sketching is to keep the sketch in proportion.
• The end of an edge is a vertex.
• A designer is likely to brainstorm several ideas before deciding on a final plan.
• An angle is formed by two intersecting lines.
• Points may be represented by simple dots.
