The views represent the exact shape of an object as seen from one side at a time as you are looking perpendicularly to it. Each right angle is called a quadrant. If the views of an object are taken by placing it in the third quadrant of dihedral or third octant of a trihedral tingle. Powerpoint to explain orthographic projection, followed by isometric projection. 1. O. This 16 page booklet is ideal as an introduction to year 7 and contains instruction and exercises which can be used as classwork or homework. 4.

Depth is not shown. Study the two drawings and complete the table by matching the numbered surfaces of the orthogonal drawing with the lettered surfaces of the isometric drawing. Then a specific view is drawn through every plane. These lines are perpendicular to the plane. Side view always forms beside the front view. Feel free to explore, study and enjoy paintings with PaintingValley.com Front view always comes under the top view. An example dimension is shown below.
