Three-dimensional models are extremely useful in communicating your ideas to others, but sometimes you may find that the default appearance of your model is not exactly what you want. If you are only in a schematic design stage, you might want your model to look more like a sketch instead of a finished product. Conversely, if you re trying to sell someone on an concept, you might want a realistic look that includes materials and even special lighting. AutoCAD offers a variety of tools to help you get every type of view from a simple wireframe to a fully rendered image complete with chrome and wood. In this section, you will get a preview of what is available to control the appearance of your model. Unfortunately, with the limited space of this book, I can only cover these features in general terms, but you will at least gain an understanding of what is available, and if you re adventurous, you can experiment with the tools presented in this section.
