Practical Autodesk AutoCAD 2021 and AutoCAD LT 2021

By: Yasser Shoukry, Jaiprakash Pandey

Overview of this book

AutoCAD and AutoCAD LT are one of the most versatile software applications for architectural and engineering designs and the most popular computer-aided design (CAD) platform for 2D drafting and 3D modeling. This hands-on guide will take you through everything you need to know to make the most out of this powerful tool, starting from a simple tour of the user interface through to using advanced tools. Starting with basic drawing shapes and functions, you'll get to grips with the fundamentals of CAD designs. You’ll then learn about effective drawing management using layers, dynamic blocks, and groups and discover how to add annotations and plot like professionals. The book delves into 3D modeling and helps you convert your 2D drawings into 3D models and shapes. As you progress, you’ll cover advanced tools and features such as isometric drawings, drawing utilities for managing and recovering complex files, quantity surveying, and multidisciplinary drawing files using xRefs, and you'll learn how to implement them with the help of practical exercises at the end of each chapter. Finally, you’ll get to grips with rendering and visualizing your designs in AutoCAD. By the end of the book, you’ll have developed a solid understanding of CAD principles and be able to work with AutoCAD software confidently to build impressive 2D and 3D drawings.

Using Boolean operations

Boolean operations are essential in any 3D modeling software. AutoCAD can perform all kinds of Boolean operations on 3D solid bodies and on planar surfaces. The following sections will cover the Boolean operation commands in detail, and these are as follows:

  • Using the union command
  • Using the subtract command
  • Using the intersect command

Let's start by looking at the union command in more detail.

Using the union command

The union command is a handy tool when creating complicated 3D models since, in many cases, the 3D object that is required to be created can be broken down into a number of simple 3D shapes. So you can just create the simple 3D shapes using the primitive commands and then join...
