The Hitchhiker's Guide to AutoCAD


Welcome to The Hitchhiker’s Guide to AutoCAD—your guide to the basic 42 commands you need to create 2D drawings using modern AutoCAD or AutoCAD LT.

This guide is a great place to get started if you just completed your initial training, or to refresh your memory if you only use AutoCAD occasionally. As you can see from the illustration, the 42 commands are grouped together according to types of activity. In addition, these groups are arranged sequentially to follow a typical workflow.

After you finish this guide, you can access the linked Help commands in each topic for more information, or you can return to the guide later to review specific topics. Also, try to find someone who will be able to answer your occasional questions. The product discussion groups ( and Autodesk blogs are good resources.
