Chapter 14 Fundamentals of 3D Modeling

14-1 Introduction

This chapter introduces the fundamental concepts needed to produce 3D models in AutoCAD using the 3D Modeling tools with the acad3D and acadiso3D templates. You will make the 3D Modeling workspace current. This workspace presents many additional tools that are absent from the Drawing & Annotation workspace you have used up until now. This chapter also shows how to change viewpoints and how to create, save, and work with user-defined coordinate systems called user coordinate systems, or UCSs.

Note

A workspace is a collection of menus and tools that you use to make relevant settings and select 3D commands. You can access workspaces by using the Quick Access Toolbar or by clicking the ...
