Autodesk AutoCAD 2013 Practical 3D Drafting and Design


Overview of this book

AutoCAD is a computer-aided design (CAD) and drafting software application. AutoCAD supports both 2D and 3D formats. AutoCAD is used in a range of industries and is utilized by architects, project managers, and engineers, among others."Autodesk AutoCAD 2013 Practical 3D Drafting and Design" will take you beyond the 2D frontier and help you create accurate 3D models that simulate reality. This book is crammed full of creative and practical tutorials which will help you master the third dimension. From exercises on coordinate systems to creating solids and surfaces from 2D, you will wonder how you ever designed without this resource by your side."Autodesk AutoCAD 2013 Practical 3D Drafting and Design" is full of hands-on studies and projects that will help develop your 3D skills. Starting from the assumption of only a very basic knowledge of AutoCAD, this book will help you master 3D visualization and coordinate systems, create 3D models from 2D drawings, and from basic shapes, measure volumes, and other information, obtain 2D construction drawings from 3D models as well as how to apply lights and materials to get photorealistic images.

Chapter 3. Coordinate Systems

Along with visualization, the creation of other working planes is imperative for proper 3D modeling. Frequently, we have to create objects that are not aligned with the current working plane. Instead of creating and aligning them to the final position, sometimes it is much faster to define the correct working plane and only then proceed to create objects. We must not forget that an important part of AutoCAD commands work only in 2D (the XY plane).

In this chapter, we will cover:

  • The world coordinate system

  • How to create and apply user coordinate systems

  • The UCS command

  • Creating UCS by moving and orienting the icon

  • When and how to apply dynamic coordinate systems

  • Coordinate system icons

  • Important variables to know
