Making the Most of Model Space

After you've decided on drawing scale and sheet size, you're ready to set up your drawing. Most drawings require a two-part setup:

  1. Set up model space, where you'll create most of your drawing.
  2. Create one or more paper space layouts for plotting.

As I explain in Chapter 2, model space is the infinitely large, three-dimensional environment in which you create the “real” objects you're drawing. You can set up your model space as described in this section; Chapter 5 introduces you to setting up your paper space layouts.

  1. Click the Application button and then choose Units from the Drawing Utilities group.

    The Drawing Units dialog box appears, as shown in Figure 4-4.

  2. Choose a linear unit type from the Length Type drop-down list.

    Choose the type of unit representation that's appropriate for your work. Engineering and Architectural units are displayed in feet and inches; the other types of units aren't tied to any particular unit of measurement. You decide whether each unit represents a millimeter, centimeter, meter, inch, foot, or something else. Your choice is much simpler if you're working in metric: Choose Decimal units.
