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.

The Object Snap override

Sometimes, it can be overwhelming to work with all these Object Snaps, and in drawings where there are lots of snap points close to each other, it can really get difficult to snap to any specific point. In those situations, you can use the Object Snap override to snap to the point that you need, overriding all other points even when they are active on the Object Snap menu.

To use the Object Snap override, select any draw command, preferably the Line commands, and then press and hold the Shift key until you see the override icon next to the cursor, as shown:

When you see the override icon, right-click on your mouse and you will get an Object Snap menu. Select the Object Snap point that you want to use for that command and then move your cursor close to the drawing. You will notice that now,...
