Oblique Perspective



Multi-view Projections

• Reference material – BTG Chap 4

• Advantage – Represent features of an object accurately

• Example Problem



Multi-view Drawing

A collection of flat 2-D drawings that work together to give an accurate overall object.



Defining the Six Principal Views



Which Views to Present?

• General Guidelines

• Pick for the Front View the view that is most descriptive of object

• Most common selection is to use: Front, Right

Side, and Top

Steps in Creating the Three-View Sketch




Step 1 - Lightly Block Three Views

Use very light lines for drawing in the construction lines




Step 2 - Lightly Block Major Features




Step 3 - Add Features, Use Miter Line




Step 4 - Add Final Lines
