•Mastering Auto Cad was design to demonstrate commands in
the text of every day activities that we encounter in our work.
•It shows what commands to be used in given condition.
•The AutoCAD instant references is the perfect companion to mastering
AutoCAD for Mechanical Engineers.
•It also means that to include a photo –graph in AutoCAD drawing.
