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.

Primitive surfaces

In the previous chapter, we explained how to create surfaces from linear objects with the EXTRUDE, REVOLVE, SWEEP, or LOFT commands. Here we present a command to create rectangular surfaces or delimited by planar objects.

Creating planar surfaces

Here is a command to create planar surfaces.

The PLANESURF command

The PLANESURF command (no alias) creates planar surfaces defined by two opposite corners or delimited by one or more existing objects.

By default, the command just prompts for two opposite corners and creates a rectangular surface:

Specify first corner or [Object] <Object>: Point
Specify other corner: Point

The command has only one option, Object.

  • Object: This option prompts for the selection of objects. We can select lines, arcs, circles, ellipses, 2D polylines, 3D planar polylines, planar splines, regions, and 3D faces. For each closed object or set of objects that form a closed boundary, the option creates a surface. By default, the original...
