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 along a path

The last command to create solids and surfaces from linear objects is presented next.

The SWEEP command

The SWEEP command (no alias) creates a solid or surface by extruding sections along a path. If the section is open or if the MOde option is set to Surface, a surface is created.

The path can be a line, arc, elliptical arc, 2D or 3D polylines, 2D or 3D splines, circles, ellipses, helixes, and surface or solid edges.

This command starts by displaying the same information as in previous commands and asks for one or more objects that define the section:

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

By default, we select the linear object that defines the path, and the sweep object is created. The section is placed normal to the path with its center aligned to it:

Select sweep path or [Alignment/Base point/Scale/Twist]: Selection

We have some options available:

  • Alignment...
