Angles
Angle will only print correctly, if the view is on the plane of that angle
36
Interpreting Views• One method of interpreting sketches
is to reverse the mental process used in projecting them
• Each view provides certain definite information about the shape of the object and all are necessary to visualize it completely
37
First- and Third-Angle Projection
• There are two main systems used for projecting and unfolding the views:– Third-angle projection which is used in
the United States, Canada and some other countries
– First-angle projection which is primarily used in Europe and Asia
• You should understand both methodsWe will only use 3rd angle
