The association of each task with a task type shows how 3D objects will be displayed
within the 4D simulation, along with their time associations. The available options
in the Navisworks TimeLiner for the task type are “Construct,” “Demolish,” and
“Temporary”; however, new task types can be added, or existing types can be renamed.
The available options in the Navisworks TimeLiner for visualizing 3D items that are
linked with predefined task types are none, hide, and model appearance. “Construct”
is mainly used for tasks whose attached 3D objects need to be constructed. The default
start appearance of “Construct” is green (90% transparent), and the end appearance
is “model appearance.” “Demolish” tasks are the ones whose attached 3D objects
will be demolished during or after the construction. The default start appearance of
“Demolish” is red (90% transparent), and the end appearance is “hide.” The final task
type, “Temporary,” represents the associated objects when the relevant tasks are solely
temporary items within the execution of the project. The default start appearance of
“Temporary” is yellow (90% transparent), and the end appearance is “hide.” Also,
new task types can be created by selecting “Add” and entering a new name for the
task type, as shown in Figure 15.15.
The “Appearance Definitions” command, as shown in Figure 15.14, enables the
selection of predefined or custom-created appearances that can be used to display
