           D. Click the OK button to accept the changes, and the program will appear
              as shown in Figure 5. N ote that the grids appear in two view windows
              tiled vertically, an X-Y Plane View on the left and a 3-D View on the
              right. The number of view windows may be changed using the drop-
              down arrow located in the top right corner of each window.
              The “Plan” view is active in Figure 5. When the window is active, the
              display title bar is highlighted. Set a view active by clicking anywhere in
              the view window. If you are unable to see the grid bubbles in this view,
              click the View menu > Zoom Out One Step command until they be-
              come visible.
              Note that the Global Axes are displayed as well, and that the Z positive is
              in the “up” direction. When SAP2000 refers to the direction of gravity,
              this is in the negative Z direction, or “down.”
