Dates” choice enables the user to define the time interval within which the simulation
will run. The interval size of the simulation can be defined either as a percentage of
the overall simulation or as a number of weeks, days, hours, and so on. Also, the
type of simulation can be defined in terms of the planned or actual schedule and will
be displayed in the animation. The snapshots of the 4D animation of the building
component are shown in Figures 15.23 through 15.29.
Exporting Snapshots and Animation
In addition to the dynamic visualization of the 4D model described in the previous
section, the 4D model also can be visualized as a series of snapshots and a movie show-
ing the construction schedule. The snapshots and/or animation of the model can be
exported as an external file by utilizing the “Export Animation” interface of Navis-
works. Figure 15.30 shows the “Export Animation” box displayed in the “Simulate”
tab of TimeLiner. The animation of the model can also be exported by using the “An-
imation Export” dialog box given in the File menu. The export settings also can be
