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.

Summary


This chapter includes all commands and concepts related to rendering and lighting. Rendering allows us to obtain photorealistic images from our 3D scene.

General concepts and a typical workflow were presented, followed by the RENDER command, the main command to render, and also save the render image. Other related commands are: RENDERWIN to display the render windows; RENDERCROP to render just some part of the viewport, and is useful for testing; SAVEIMG to save a rendered image in viewport; RPREF to specify all default parameters used for rendering, including activation of global illumination and final gather; and RENDERPRESETS to create rendering presets.

We then introduced illumination, starting with default, generic, and photometric lighting. To apply the natural lighting of the Sun, there is the SUNPROPERTIES command, which can also consider sky lighting and background. GEOGRAPHICLOCATION specifies the location and the north direction. There are several commands to apply artificial...
