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.

Conversion between 2D and 3D

It is very common during the process of 3D modeling to break down the creation process into drawing 2D shapes (representing cross-sections or bases), then extruding or revolving to create the 3D object. Another possible scenario is to have an entire 2D drawing that needs to be converted to a 3D model. In this chapter, the following topics will be discussed in detail (these are the 2D-to-3D conversion commands):

  • Using the Extrude command
  • Using the Revolve command
  • Using the Sweep command
  • Using the Loft command
  • Using the Presspull command

In addition to that, the opposite scenario might be the case, where a 3D model is present and we want to create a 2D shape from it. This task can easily be done using either of the following:

  • The Flatshot command
  • The Section tool

Both of these command tools will also be demonstrated in detail in this chapter. Let...
