Page 2 Introduction AutoCAD Students: Welcome to Learn AutoCAD!: Mechanical Drawing Using AutoCAD 2016. This book is designed to give you an introduction to Mechanical Drawing using the AutoCAD 2016 software. These projects were originally developed based on the projects used for my Introduction to AutoCAD course at Glendale Community College in Glendale, California. The operating system used for these projects is Windows® 10. The book is divided into two parts: 2D Tutorials and 3D Tutorials of the projects. All of these projects have step-by-step procedures, screenshots, and demonstration videos on the companion website at: www.mechdrawautocad.com. The videos will also provide additional instruction of the tools and techniques being used for each project. It is recommended that you view these either before or during the drawing of the projects. Please Note: Access to the videos and support files require a Google Account. If you would prefer to access the files using a different method, please contact the author at [email protected] so that different arrangements for file access can be made. You will receive an introduction to the 3D portion of the software and complete the projects using this portion of the program. Once you have completed the tutorials, you may wish to print your drawings and assemble them into a portfolio. You should have a general knowledge of orthographic projection, linetypes, vellum and border sizes, welding symbology, and dimensioning practice. It is my hope that you will find this process an enjoyable and informative one. Once you have completed the book please feel free to email me with any suggestions and/or compliments about the book. Enjoy, David Martin [email protected] www.mechdrawautocad.com Introduction Learn AutoCAD! Page 3 Before Beginning to Draw Each project has set of procedures that will aid you in drawing the project. The units that are used are either in inches or millimeters. Before beginning the project, be sure to set up the file with the appropriate drawing units and layers. As the book projects progress, the setup for new projects will change. A good strategy is to use a previous project that is similar to the current project to aid in the set-up of the file. If a template does not exist, create one from a completed drawing. Before beginning the projects, it is recommended to print out the PDF versions of the completed projects. This way you will have a reference for the measurements and locations of the features of each part. High- resolution files of the PDF versions of the projects are available on the book website. Video Tutorials There are on-line video tutorials available for student use at: www.mechdrawautocad.com Permission to access these files will be given as part of book purchase. The author may be contacted by email at [email protected]. You will also be required to create a Google Account or contact the author for other methods to access the files. This account and the associated email account will be used to access the tutorial videos. After the email is sent, you will receive instructions on how to access the tutorials and support files. Title Blocks and Other Support Files Title Blocks and other support files will be provided on the book website. Student should copy these files to their local drive and/or flash drive. File Management One of the most important issues while learning a computer-based skill is the management of the various files created. Always create a backup copy of your working files. Students should use folders to organize their work. A recommended method to do this will be covered during the first project. Introduction Learn AutoCAD! Page 4 AutoCAD Educational License Autodesk Inc. provides free educational licenses of their software. To download the software, registration on the Autodesk site is required. Access the Download Trial link at the web address below: http://www.autodesk.com/education/free-software/all If you are a student or teacher at an academic institution, you are eligible to receive a variety of products for free from the Autodesk site. Please visit the Autodesk.com site for terms and conditions. Mechanical Drawing Layer Setup Use this guide for the Layer Setup for the drawings. The procedure to setup the levels for the drawing will be covered later in the book. Layer Properties Manager Dialog Box Use the following level setup for both imperial and metric drawings: Layer Name Color Linetype Lineweight Object Lines Green (2) 0 2 Hidden Lines White (0) (Hidden) 0 (Center) or Centerlines White (0) 0 (Center-Short) Dimensions White (0) 0 0 Text White (0) 0 0 Hatching Red (3) 0 0 Border Lines* Yellow (4) 0 2 Points* Magenta (5) 0 6 Tags* White (0) 0 0 *Used for A-Size and B-Size Border Files. Introduction Learn AutoCAD! Page 5 Drawing Setup for the 2D Projects Please watch the Tutorial Video for Project #1 for information of drawing setup. The steps are also covered in the tutorial for the projects. This chart shows the drafting settings for the 12 projects.

Page 6 Project Volumes for 3D Projects AutoCAD can measure the volume of the 3D projects that you will be drawing. This provides an easy way of determining if you drew the object the correct size and shape. Use these volumes as a guide when calculating the volumes of the 3D versions of your projects. Use the VOLUME key-in command to measure the volume of your project. Project # Volume Units 1 32.8393 Cubic Inches 2 9.4599 Cubic Inches 3 3.0664 Cubic Inches 4 5.7910 Cubic Inches 5 12.4649 Cubic Inches 6 9.5502 Cubic Inches 7 1.7920 Cubic Inches 8 (Cam) 2.2996 Cubic Inches 8 (Drive Wheel) 2.2619 Cubic Inches 8 (Base) 10.9718 Cubic Inches 8 (Shaft) 0.1474 Cubic Inches 8 (Key) 0.0097 Cubic Inches 9 163987.3199 Cubic Millimeters 10 6.8571 Cubic Inches 11* 13.5996 Cubic Inches Note: To check the volume of Project #11, create a copy of the parts and then union them together. Part One – Projects – 2D Versions Learn AutoCAD! Page 7 Part One Projects 2D Versions Project #1 – Absolute Coordinate Exercise Learn AutoCAD! Page 8 Projects – 2D Versions Project #1 – Absolute Coordinate Exercise Filename: PROJ-01.dwg Note: All screenshots are from the Autodesk® AutoCAD® software. Description: This is the first project of the book. It is designed to introduce you to the AutoCAD interface and to give you practice in the use of the Absolute Coordinate system. A completed version of the project is shown at the end of the tutorial. You will also be introduced to the Move, Copy, Offset, and Text tools and the use of the various commands to control the font, size, and the spacing of the various text elements in the drawing. Setting up a Folder Structure and Downloading the Support Files 1. Before beginning to draw, you will set up a folder structure to save and organize your drawing and support files. 2. On your desktop, open your File Explorer window. 3. On the drive/location of your choice, create a folder called AutoCAD Projects. All your files used and created while using this book will be contained in this folder. 4. Within this folder, create a set of sub-folders as shown. More folders will be created later on in the book. Note: In this case the folders were created on the Desktop. If you are using different Folder Structure computers and wish for you files to be mobile, you may wish to use a Flash Drive instead. 5. Open the website for the text book located at www.mechdrawautocad.com. Find and download the Support Files from the Google Drive folder and copy the files into your Support Files folder on your local drive. Note: This folder contains all the files you will need to complete the book projects.
