Chapter 2: Le Tour de AutoCAD 2007
As with other Windows programs, the menus at the top of the AutoCAD screen enable you to access most of the program’s functions and are the easiest-to-remember method of issuing commands. When you want to get real work done, you need to combine the pull-down menus with other methods — especially entering options at the keyboard or choosing them from the right-click menus. We show you how throughout this book.
And They’re Off: AutoCAD’s Opening Screen
By default, when you start an AutoCAD 2007 session, a dialog box (see Figure 2-1) asks in which of the two standard workspaces you want to start your drawing session:
3D Modeling: Opens a new drawing file configured for a 3D modeling environment with navigation, visualization, and modeling tools suitable for working in 3D.
AutoCAD Classic: Opens a new drawing configured for a 2D drafting environment, with drafting and drawing management tools suitable for working in 2D.

Will that be 2D or 3D? Make your choice here.
A workspace is a collection of menus, palettes, and toolbars tailored for specific tasks, such as 3D modeling or 2D drafting. AutoCAD 2007 includes two workspaces for just those purposes, called 3D Modeling and AutoCAD Classic, and you can easily create additional workspaces to suit your requirements. For more information, look up “workspace” in the online help system.
22 Part I: AutoCAD 101_______________________________________________________________________________
In this chapter we’re going to focus on drawing rather than modeling — we’ll look at visualizing and navigating in 3D space in Chapter 9.
The Workstations dialog box appears only when you start an AutoCAD session — it’s not there if AutoCAD is already open. If that’s the case and you want to switch between 2D drafting and 3D modeling, follow these steps:
1. Choose ToolsOWorkspacesOAutoCAD Classic.
Assuming the 3D Modeling workspace is current, a bunch of toolbars and palettes open and close. You end up with the Tool Palettes and the Sheet Set Manager displayed at the left and right sides of the screen. (Don’t worry about what those are for right now — we’ll get to them in later chapters.)
2. Choose FileONew or open a 2D AutoCAD drawing file.
If you choose to start a new file, the Select Template dialog box opens. Choose acad.dwt if you want to work in imperial units, or acadiso.dwt, if you want to work in metric.
To switch back from 3D modeling to a 2D drafting environment, reverse the procedure as follows:
3. Choose ToolsOWorkspaces O3D Modeling.
After more whizzing and whirring, AutoCAD closes Sheet Set Manager and opens the Modeling tab of the Tool Palettes and the Dashboard (we discuss these features in Chapter 9).
4. Choose FileONew or open a 3D AutoCAD model file.
If you choose to start a new file, the Select Template dialog box opens. Choose acad3d.dwt if you want to work in imperial units, or acadiso3d. dwt, if you want to work in metric.
For the remainder of this chapter (and nearly all the rest of the book), we focus on 2D drafting, by far the easier way of getting your feet wet with AutoCAD.
After you switch to the AutoCAD Classic workspace, AutoCAD displays its old familiar 2D interface, as shown in Figure 2-2. You can close the Sheet Set Manager and Tool Palettes for now — we describe how to turn them back on and how to use them later in this chapter.
If you don’t see the Workstations dialog box shown in Figure 2-1, it means that you or someone who uses your computer checked that little box that says Don’t Show Me This Again down there in the lower-left corner. If you want to restore the Workstations dialog box, choose ToolsOOptions, and on the Systems tab, General Options area, check the box beside Show All Warning Messages. Then click OK.

If you have a previous version of AutoCAD on your computer, AutoCAD 2007 displays a Migrate Settings dialog box the first time you run the program. Unless you’re a competent AutoCAD user who is reading this book to find out about the new features, we recommend that you click Cancel and start fresh. If you later decide you want to migrate your custom settings, you can do so by choosing StartOAll ProgramsOAutodeskOAutoCAD 2007OMigrate Custom Settings and then choosing the installed version from which you want to migrate settings. Be warned, however, that doing so will overwrite any new customization you’ve added to AutoCAD 2007.
Those Well-Washed Windows
As shown in Figure 2-2, much of the AutoCAD screen is standard Windows fare — title bars, a menu bar, toolbars, and a status bar.
