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.

Editing surfaces


There is a command that is very useful when it comes to assigning thickness to surfaces.

The THICKEN command

The THICKEN command (no alias) allows us to apply a thickness to surfaces, thus creating a 3D solid. The command starts by prompting the surfaces to thicken:

Command: THICKEN
Select surfaces to thicken: Selection

We specify the thickness to be applied to all selected surfaces. It can be positive or negative:

Specify thickness <0.0000>: Value

Note

If, when applying the command, there are self-intersections of volume, the operation may fail. If it fails, we may try a negative value.
