Using Isometric commands is one of the simplest ways to give a 3-D representation while using only 2-D commands. This has been the usual way of doing things before CAD allowed true 3-D work to be done. Many times an isometric drawing is used to compliment a 3 view orthographic drawing.

You may have already figured out why CAD has many advantages over manual drafting. One big advantage is that once you've drawn something, you shouldn't have to draw it again. If you manually drew a house plan, you would have to draw a front elevation, side elevations, and possibly a perspective view. With one 3-D CAD model, you can generate views from any angle either inside or outside the house and animations. Afterwards, if your client needs something changed, you can then make the changes once. If you're drawing mechanical parts, you can generate virtual prototypes or even create rapid prototypes. In this manner Boeing was able to design and prototype the 777 jetliner. This level of engineering would be impossible without CAD.

So far the tutorials have dealt with drawing and modifying objects. This lesson will be a primer on how to move around in your drawing. With simple drawings like the assignments in Level 1, you didn't have much need for moving around or zooming in your drawing. The more complex your drawing is, the more you will need to master the power of zooming and panning. Mastering these techniques will enable you to be more productive in your drawings and life will be better.

Now that you have learned how to draw objects and modify them using special commands, you need to know more ways to change the properties of an object. For instance, you may have made a spelling mistake in your text. You could erase it and re-create it, or you could double-click on it and just correct the error. Maybe you drew something on the wrong layer? This process is an extremely important tool to help you with your CAD work.

There are many ways to do things in AutoCAD. To enter distances, you have been shown Absolute, Relative and Polar Co-ordinates. Now you will be shown four more ways to tell AutoCAD where the locate the point you are drawing to (the easy way).

This lesson will introduce you to text, dimensioning and the concept of layers. Without dimensions you can not communicate what size your objects are. Is it a real house or a doll house? Text is used to convey information that is needed other than size - materials, manufacturing process, part numbers, etc.

Now it's time to learn a few more commands. Like all of the commands learned so far, these too will be ones that you will use regularly.
