- How are pictorial drawings used?
- What is the main use of perspective drawings?
- What are the three main types of perspective drawings?
Answers
- False
- Oblique projection is a simple type of graphical projection used for producing pictorial, two-di-
mensional images of three-dimensional objects. - True
- They appear elliptical.
- An auxiliary view is an angle at which one can view an object that is not one of the primary views
for an Orthographic projection. - True
- An axonometric drawing is one that is accurately scaled and depicts an object that has been ro-
tated on its axes and is inclined from a regular parallel position to give it a three-dimensional ap-
pearance. - Pictorial drawings are used to depict a three-dimensional view of an object and to convey as
much information as possible while helping the reader visualize the object drawn. - Perspective drawings are used mainly for illustrative purposes.
- The main types of perspective drawings are: one-point perspective, two-point perspective and
three-point perspective.
