It is always the case that drawings get edited and changed through let's say for example a construction process of a building. Objects can be modified once they've been drafted allowing you to edit drawings and change drawings as per specification. If you're happy with that it's purely a right click or Enter on the keyboard. This point finds the area between the circle and the rectangle and if you preview that using the hatch dialog box you can see the hatch on the screen. We're now going to hatch the area between the rectangle and the circle by picking an internal point in the area as shown. Now the idea of this is using objects snaps, you'll notice those symbols appearing on the screen, these object snaps will be covered later in the course but they allow you to position objects and center of circles accurately. Clicking on the Down Arrows in the panels provide you with more commands and in this case a circle where we're going to specify the center of the radius.
Now once the two corners are specified the rectangle appears on the screen. In this particular case a rectangle is going to be created, purely freehand on the screen at this point. So as you can see you can extend the panels at the top of the screen and working your way through these panels you can draft and create objects. Now the whole idea of AutoCAD is a primarily 2D drafting tool and as you can see the crosshair is moving up to the Draw Panel on the Ribbon on the top of the screen and this is the new AutoCAD user interface, the Ribbon and the panels are new to AutoCAD 2009. What we're going to look at here is the AutoCAD user interface briefly and we're going to draw a couple of AutoCAD objects just to show you what can be done within AutoCAD. Welcome to the getting started section of the AutoCAD 2009 Basic 2D Concept course.
