Overview of this book

AutoCAD is 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 2nd edition guide will take you through everything you need to know to make the most out of this powerful tool, from a simple tour of the user interface 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 plots like a professional. As you progress, the book will show you how to convert your 2D drawings into 3D models and shapes. You’ll also discover advanced features, such as isometric drawings, drawing utilities for managing and recovering complex files, quantity surveying, and multidisciplinary drawing files using xRefs. Finally, you’ll focus on rendering and visualizing your designs in AutoCAD. By the end of this 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 creations.

Cleaning and fixing drawing issues

Just like any physical object, drawings tend to get untidy over time, and usually, they accumulate a lot of redundant objects, such as zero-length geometries, DGN linetypes, and unused named objects that not only bloat the file size but also start creating errors in the drawing.

There are many inbuilt tools in AutoCAD that help you keep drawings clean, and even when your drawings seem to show errors, these tools can fix those errors too. In this section, we will talk about four such tools: PURGE, OVERKILL, AUDIT, and RECOVER.

Using PURGE to clean drawings

Open any drawing that you suspect has redundant objects, type PURGE, and press the Enter key. The Purge window will open, which looks like this:

In the Purge window, you will find two large buttons at the top: Purgeable Items and Find Non-Purgeable Items. By default, Purgeable Items is...
