You can display multiple viewboxes one behind the other in the Viewer. Click the viewbox tab at the bottom of the Viewer window to switch between viewboxes. The number of viewboxes that appear the first time you access the DP Editor is copied from the system default display protocol. From this base, you can add or remove viewboxes.
1. From the DP menu, select Open DP Editor.
2. In the DP Editor dialog box, click Next twice.
3. Click Add 
.
A new viewbox (represented by an additional viewbox tab) is added to the display protocol.
4. In the Monitors section, specify the size and location of the viewbox:
Number of viewbox monitors: Enter the number of monitors across which the viewbox displays (one or two).
Start Monitor: Enter the monitor number where the viewbox begins.
For example, in a two-monitor configuration, 1 indicates the viewbox begins on the left monitor and 2 indicates the viewbox begins on the right monitor.
NOTE: The viewbox appears across more than one monitor only if you defined the monitor configuration to include two monitors. See Creating a New Display Protocol.
