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.

Surface analysis


There are three commands, since Version 2011, that perform surface analysis and another activity to adjust options. These analysis are useful when needing to check continuity, curvature, and draft angles, like in the mould industry.

These commands can not be used with the 2D wireframe visual style and are only available on the ribbon, Surface panel.

Types of analysis and commands

AutoCAD considers three types of analysis, which can be applied to surfaces or solids:

  • Zebra analysis: Surfaces are analyzed about their continuity by projecting parallel black and white stripes onto the model (default), where surfaces meet and stripes allow analyzing curvature and tangency

  • Curvature analysis: Surfaces are analyzed about their curvature with a color gradient

  • Draft analysis: Surfaces are analyzed about how easy they would be separated from the mould

The ANALYSISZEBRA command

The ANALYSISZEBRA command (alias ZEBRA) prompts for the selection of solids and surfaces and displays stripes...
