customizable values available with the built in templates are:
■ Column Name. Choose which column in the
Tasks Tab you want to compare Item names to. The default
is the Task Name, though you may also choose one of the ten User columns, identified in the
Field

.
■ Items. Choose what you would like the value in the Column Name to be compared to in the model
scene. The default is Item name, though you may also choose either Selection Sets or Layers.

choose Ignoring to ignore case sensitivity.

Validate Project Schedule
You can check the validity of your schedule, by identifying items that have not been included in any task, are
duplicated in multiple tasks or, are in overlapping tasks. This is especially useful, when you use rules to attach
tasks.
An item may remain unattached for a number of reasons. For example, a task in the project scheduling file is
omitted, or the geometry item has not been included in a selection or search set.
To check a schedule
1 If the TimeLiner window is not already open, click Home tab ➤ Tools panel ➤ TimeLiner .
2 In the TimeLiner window, the Tasks tab, right-click the tasks view, and click Check.
3 Select one of the available options:
■ Find Uncontained Items. Choose this to select any items in the scene that are not attached to a task, or
are not contained within any other item attached to a task.
