Section 1 Summary

 

This is an isometric illustration of a house with a white picket fence.

Hemera/Thinkstock

Graphic artists have a variety of techniques at their disposal to make two-dimensional illustrations appear three-dimensional. One of these techniques is isometric drawing. The sketch of the house is an isometric representation.

 

As part of the Module 5 Project: Produce a Set of Drawings and a Scale Model, you are expected to sketch an isometric diagram of a box by using isometric dot paper as an aid. You explored this technique in Lesson 1.

 

In Lessons 2 and 3 you examined drawing orthographic views of three-dimensional objects. Orthographic views are ways of presenting in two dimensions a three-dimensional object from more than one point of view. Orthographic views reveal what could be hidden with only a single drawing. For instance, imagine that you want to buy the house shown in the illustration. You would want to see other views of the house, such as the back and the far side.
