Backup File

AitoCAD can be set to automatically backup youe drawing and save it this is a safe gaurd in case your file gets corrupted. It is saved with a .BAK

Layer

All objects are drawn on a layer. you can group objects (such as electrical) on a single layer and organize your drawing.

Wizard

An easy step-by-step instruction set to help you set-up certain aspects of your drawing

Object
