Engineering drawing Questions and
Correct Answers
projection line
Ans✅✅: an 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
Ans✅✅: a line that is used to represent an edge that is not directly
visible
center line
Ans✅✅: a line which defines the center of arcs, circles, or
symmetrical parts
scale-model
Ans✅✅: an enlarged or reduced representation of an object that is
usually intended for study purposes
working drawing
Ans✅✅: drawings that convey all of the information needed to
manufacture and assemble a design
perspective sketching
Ans✅✅: a 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
Pretest - Stuvia US
, 2
Ans✅✅: a form of pictorial sketch in which all 3 drawings axis form
equal angles of 120 degrees with the plane of projection
construction line
Ans✅✅: lightly drawn lines to guide drawing other lines and shapes
leader line
Ans✅✅: line which indicates dimensions of arcs, circles, and detail
long-break line
Ans✅✅: a line which indicates that a very long object with uniform
detail is drawn foreshortened
object line
Ans✅✅: a heavy solid line used on a drawing to represent the outline
of an object
design brief
Ans✅✅: a written plan that identifies a problem to be solved, its
criteria, and its constraints
design process
