Section 1: Viewing and Representing 3-D Objects

 

Section 1 Introduction

 

This is an illustration of orthographic views of a sports car.

 

If you are interested in cars, you have probably flipped through brochures or magazines or checked online to look at photos and illustrations or videos that advertise the latest models. Viewing a single photograph or drawing generally isn’t enough—to appreciate all the latest features, you need to study the vehicles from all sides.

 

In the Module 5 Project: Produce a Set of Drawings and a Scale Model, you will create a model of a three-dimensional object. One of your tasks will be to draw this model from various points of view. In Section 1 you will explore how to sketch these views. As well, you will use isometric dot paper to investigate how to represent a three-dimensional object in two dimensions.
