In this sample chapter from Engineering Design Graphics with Autodesk Inventor 2020, author James D. Bethune presents orthographic views using third-angle projection in accordance with American National Standards Institute (ANSI) standards. International Organization for Standardization (ISO) first-angle projections are also presented.

Introduction

Orthographic views may be created directly from 3D Inventor models. Orthographic views are two-dimensional views used to define a three-dimensional model. Unless the model is of uniform thickness, more than one orthographic view is necessary to define the model’s shape. Standard practice calls for three orthographic views: a front, a top, and a right-side view, although more or fewer views may be used as needed.

  • Two-dimensional views used to define a three-dimensional model. (Usually more than one view is needed to define a 3D model.)

Modern machines can work directly from the information generated when a solid 3D model is created, so the need for orthographic views—blueprints—is not as critical as it once was; however, there are still many drawings in existence that are used for production and reference. The ability to create and read orthographic views remains an important engineering skill.

This chapter presents orthographic views using third-angle projection in accordance with American National Standards Institute (ANSI) standards. International Organization for Standardization (ISO) first-angle projections are also presented.
