98 Part I: AutoCAD 101
Pick two points to define a rectangle that falls within the drawing area of your title block (or within the plottable area of the sheet, if you chose no title block in Step 6).
AutoCAD represents the plottable area of the sheet with a dashed rectangle near the edge of the sheet. If you don’t select a location for the viewport(s), the Create Layout Wizard creates a viewport that fills the plottable area of the sheet.
9. Click Finish.
AutoCAD creates the new layout.
Copying and changing layouts
After you create a layout, you can delete, copy, rename, and otherwise manipulate it by right-clicking its tab. Figure 4-11 shows the right-click menu options.
The From Template option refers to layout templates. After you create layouts in a template (DWT) or drawing (DWG) file, you can use the From Template option to import these layouts into the current drawing. For details, see the LAYOUT command’s Template option in the Command Reference section of online help.

Chapter 4: Setup for Success
Many drawings require only one paper space layout. If you always plot the same view of the model and always plot to the same device and on the same size paper, a single paper space layout should suffice. If you want to plot your model in different ways (for example, at different scales, with different layers visible, with different areas visible, or with different plotted line characteristics), you may want to create additional paper space layouts.
Some different ways of plotting the same model can be handled in a single paper space layout with different page setups. See Chapter 13 for more details. If your projects require lots of drawings, you can parlay layouts into sheet sets — a feature that makes for more sophisticated creation, management, plotting, and electronic transfer of multisheet drawing sets. Again, see Chapter 13 for more information.
If you want to add another viewport to an existing layout, you need to become familiar with the MVIEW command. (See the MVIEW command in the Command Reference section of AutoCAD online help.) After you have the concepts down, using the Viewports dialog box (choose ViewOViewportsONew Viewports) and Viewports toolbar can help you create, scale, and manage viewports more efficiently.
Lost in paper space
After you create a paper space layout, you suddenly have two views of the same drawing geometry: the view on your original Model tab and the new layout tab view (perhaps decorated with a handsome title block and other accoutrements of plotting nobility). It’s important to realize that both views are of the same geometry. If you change the model geometry on one tab, you’re changing it on all tabs because all tabs display the same model space objects.
When you make a paper space layout current by clicking its tab, you can move the crosshairs between paper space (that is, drawing and zooming on the sheet of paper) and model space (drawing and zooming on the model, inside the viewport) in several ways, including
^ Clicking the PAPER/MODEL button on the status bar.
^ In the drawing area, double-clicking over a viewport to move the
crosshairs into model space in that viewport or double-clicking outside all viewports (for example, in the gray area outside the sheet) to move the crosshairs into paper space.
^ Clicking the Maximize/Minimize Viewport button on the status bar (for more information, see Chapter 2).
^ Entering MSPACE (MS) or PSPACE (PS) at the keyboard.
100 Part I: AutoCAD 101
When the crosshairs are in model space, anything you draw or edit changes the model (and thus appears on the Model tab and on all paper space layout tabs, assuming that the given paper space layout displays that part of the underlying model). When the crosshairs are in paper space, anything you draw appears only on that one paper space layout tab. It’s as though you were drawing on an acetate sheet over the top of that sheet of plotter paper — the model beneath remains unaffected.
This distinction can be disorienting at first. To avoid confusion, stick with the following approach (at least until you’re more familiar with paper space):
If you want to edit the model, switch to the Model tab first. (Don’t try to edit the model in a paper space viewport.)
If you want to edit a particular plot layout without affecting the model, switch to that layout’s tab and make sure that the crosshairs are in paper space.
Making Templates Your Own
You can create a template from any DWG file by using the Save As dialog box. Follow these steps to save your drawing as a template:
1. Choose FileOSave As from the menu bar.
The Save Drawing As dialog box appears, as shown in Figure 4-12.

2. From the Files Of Type drop-down list, choose AutoCAD Drawing Template or AutoCAD LT Drawing Template (*.dwt).
3. Navigate to the folder where you want to store the drawing.
