As you saw in Chapter 7 the different look of the Layout tab tells you that you are in Paper Spa ou alse learned that a viewport is automatically created when you first open a Layout tab Paper Space view. The viewport displays an overall viewof your drawing to no particular scale. In this section you will work with multiple viewports in Paper Space instead of just the default single viewport you get when you open the Layout tab. This first exercise shows you how to create three new viewports at once.
1. Right-click the Draw or Modify toolbar, and select Viewports to open the Viewports toolbar. You’ll use this toolbar a bit later in this exercise.
2. Click the viewport border to select it. The viewport border is the solid rectangle surrounding your drawing, just inside the dashed rectangle.
3. Click the Erase tool to erase the viewport. Your drawing disappears. Don’t panic; remember that the viewport is like a window to Model Space. The objects in Model Space are still there.
4. Click Display Viewports Dialog in the Viewports toolbar. You can also choose View> Viewports >- New Viewports. The ‘iewports dialog box appears. This dialog box contains a set of predefined viewport layouts.
You’ll learn more about the Viewports dialog box and its options in Chapter 16
5. Click the Three Above option in the Standard Viewports list box. The box to the right shows a sample view of the Three Above layout you selected.
6. Click OK. The Speci fy fi rst corner or [Fi t] <Fit>: prompt appears.
7. Press.J to accept the default Fit option. The Fit option fits the viewport layout to the maximum area allowed in your Paper Space view. Three rectangles appear in the formation, shown in Figure 12.33.Each of these is a viewport to your Model Space. The viewport at the top fills the whore width of the drawing area; the bottom half of the screen is divided into two viewports
When you create new viewports, AutoCAD automatically fills the viewport with the extents of your Model Space drawing. You can specify an exact scale for each viewport, as you’ll see later.
Notice that the dashed line representing your paper margin has disappeared. That’s because the viewports are pushed to the margin limits thereby covering the dashed line. . You could have kept the original viewport that appeared when you first opened the Layoutl tab then added two new viewports. Completely replacing the single viewport is a bit simpler since it fits the viewports in the allowed space for you.
Reaching Inside Viewpbrts
Now suppose you need to have access to the objects within the viewports in order to adjust their display and edit your drawing.
1. Click PAPER on the status bar. This gives you control over Model Space even though you are in Paper Space. (Youcan also enter MS-l as a keyboard shortcut to entering Model Space mode.)
The first thing you notice is that the UCS icon changes b~ck to its L- shaped arrow form. It also appears in each viewport as if you had three AutoCAD windows instead of just one.
2. Move your cursor over each viewport. Notice that in one of the viewports the cursor appears as the AutoCAD crosshair cursor while in the other viewports it appears as an arrow pointer. The viewport that shows the AutoCAD cursor is the active one ¥ou can pan and zoom as well as edit objects in the active viewport
3. Click the lower-left viewport to activate it.
4.. Click View> Zoom> Window and window the elevator area.
5. Click the lower-right viewport and use View> Zoom> Wmdow to enlarge your view of a typical unit. You can also use the Pan Realtime and Zoom Realtime tools
You’ve seen.how you can zoom into a viewport view but what happens when you use the Zoom command while in Paper Space? Try the following exercise to find out.
1. Click the MODEL button on the status bar or double-click an area outside the viewports to return to Paper Space.
2. . Click the Realtime Zoom tool in the Standard toolbar then zoom into the Paper Space view: The entire view enlarges including the views in the viewports.
3. Choose View :>- Zoom :>- All or enter Z.J A.J to return to the overall view of Paper Space. This brief exercise shows that you can use the Zoom tool in Paper Space just as you would in Model Space. All the display-related commands are available including the Pan Realtime command.
Getting Back to Full-Screen Model Space
Once you’ve created viewports, you can then re-enter Model Space through the viewport using the MODEL/PAPER button on the status bar. This button performs two functions: It shows you which space you are in and it allows you to switch between the two spaces. But what if you want to quickly get back into the old familiar full-screen Model Space you were in before you entered Paper Space? The following exercise demonstrates how this is done.
1. Click the Model tab at the bottom of the drawing area, or enter Tm.J 1.J. Your drawing returns to the original full-screen Model Space view-everything is back to normal.
2. Click the Layoutl tab or enter Tm.J O.J.You ~ back in Paper Space. Notice that all the viewports are still there when you return to Paper Space. Once you’ve set up Paper Space it remains part of the drawing until you delete all the viewports. Also notice that you didn’t see the Page Setup dialog box this time. Once you’ve chosen a sheet size AutoCAD assumes that you will continue to use that sheet size and other page setup information until you tell it otherwise.
You may prefer doing most of your drawing in Model Space, using Paper Space for setting up views for plotting. Since viewport layouts are retained you won’t lose anything when you go back to Model Space to edit your drawing.
