    2D COMMANDS

    Title Bar - This will show you what program you are running andwhat the current filename is.

    Pull-down menus - These are the standard pull-down menusthrough which you can access almost all commands.

    Main toolbar - This has most of the standard Windows icons, aswell as the most common AutoCAD commands.

    Property toolbar - This toolbar gives a way to quickly modify anobject's properties, such as layer and linetype.

    Floating toolbar - This is a toolbar that can be moved around thescreen, or 'docked' as the main toolbar is.

    Drawing space - This is where you draw. You have an almostinfinite area to draw and this is just a 'section' of the entire space.

    Scrollbars - This work like in other windows programs. You canalso use the PAN command to move around your drawing.

    WCS Icon - This is here to show you which direction positive Xand positive Y go. The W means you're in the World Co-ordinateSystem. (It can be changed to a User Co-ordinate System.)

    Status Bar Tray Icons - These icons give you updates on itemslike reference files program updates and print status.

    Command line - When you type a command, you will see it here.AutoCAD uses this space to 'prompt' you for information. It willgive you a lot of information and tell you where you are in thecommand.

    Status bar - This allows to see and change different modes ofdrawing such as Ortho, Osnaps, Grid, Otrack, etc

    Crosshairs -This is your cursor when it is in the drawing space

    User co-ordinate system (UCS-Modifications made to the World

    Co-ordinate System (WCS) results in a User Co-ordinate System(UCS)
