Using Layouts to Set Up a Print - AutoCAD 2011 and AutoCAD LT 2011: No Experience Required - page 747

adjust the viewport scale to display the model space objects at 3 ⁄ 16 ″ = 1 ′ (1 = 70)
by assigning a viewport scale.
1. Select the viewport. You know that the viewport is selected, and not
the border polyline, when the Viewport Scale button appears in the
status bar.
TIP Since the viewport and the title block are drawn atop one another,
try using Selection Cycling if you're having a hard time selecting the
viewport.
2. If you are using metric units, skip this step and go on to step 3. If you
are using architectural units, click the Viewport Scale button and,
from the drop-down list, choose 3 ⁄ 16 ″ = 1 ′ -0 ″ (see Figure 14.51).
The viewport scales to 3 ⁄ 16 ″ = 1 ′ -0 ″ , and the scale is reflected on the
status bar.

TIP You can also change the viewport scale by selecting the viewport
and changing the Standard Scale value in the properties palette or Quick
properties panel.
