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.

Creating solids and surfaces by revolution

When we need a solid or surface whose section is rotated around an axis, the next command should be applied.

The REVOLVE command

The REVOLVE command (alias REV) creates a solid or surface by rotating a linear or planar object around an axis. It starts by showing the same information and prompts for the selection of sections, as seen with EXTRUDE. We can select any planar object. If an object is not closed or if the MOde option is set to Surface, a surface is created:

Command:  REVOLVE
Current wire frame density:  ISOLINES=4, Closed profiles creation mode = Solid
Select objects to revolve or [MOde]: Selection

We must then define the axis of revolution. By default, we can pick two points that define this axis, but other options are available as well. In the order we select, the points specify the positive angle direction by the right-hand rule.

Specify axis start point or define axis by [Object/X/Y/Z] <Object>: Point
Specify axis endpoint: Point...
