REVISED Engineering drawing
projection line - correct answeran imaginary line that is used to locate or project the corners, edges, and
features of the 3 dimensional objects onto an imaginary 2 dimensional surface
hidden line - correct answera line that is used to represent an edge that is not directly visible
center line - correct answera line which defines the center of arcs, circles, or symmetrical parts
scale-model - correct answeran enlarged or reduced representation of an object that is usually intended for
study purposes
working drawing - correct answerdrawings that convey all of the information needed to manufacture and
assemble a design
perspective sketching - correct answera form of pictorial sketch in which vanishing points are used to provide
the depth and distortion that is seen with the human eye
isometric sketching - correct answera form of pictorial sketch in which all 3 drawings axis form equal angles of
120 degrees with the plane of projection
construction line - correct answerlightly drawn lines to guide drawing other lines and shapes
leader line - correct answerline which indicates dimensions of arcs, circles, and detail
