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 the Presspull command

The last command in our 2D-to-3D conversion group is called Presspull. It is used to directly create an extrusion (or cut into the material) out of the face of a solid body. In addition to that, it can also directly extrude an enclosed 2D shape as we will see in this section. To start the Presspull command, you can type the command name PRESSPULL (or just type PRES) then press Enter, or alternatively you can click on the Presspull button found in the Create panel in the 3D Basics workspace, and if you are using the 3D modeling workspace, you will find the Presspull button in the Modeling panel under the Home tab, or in the Solid panel under the Solid tab, as shown in the following figure:

You can use the Presspull command to quickly extrude faces of existing 3D solid objects as follows...
