Table Of Contents
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, select Tools > TimeLiner from the menu bar.
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.
Note:
A Contained item is the child of another item. For example, if you select a Group, Block or Cell
which is comprised of various pieces of geometry, then that geometry is contained within the
Group, Block or Cell. A Group, Block or Cell may therefore be attached to a task and although
the child geometry is not directly attached itself, it is contained within an item that is attached.
Find contained items. Choose this to select any items in the scene that are either
attached to a task or contained within any other items attached to a task.
Find attached items. Choose this to select any items in the scene that are directly
attached to a task.
Find items attached to multiple tasks. Choose this to select any items in the scene that
are directly attached to more than one task.
Find items contained in multiple tasks. Choose this to select any items in the scene
that are either attached to, or contained within any other item that is attached to more
than one task.
Find items attached to overlapping tasks. Choose this to select any items in the scene
that are attached to more than one task, where the task durations overlap.
Find items contained in overlapping tasks. Choose this to select any items in the
scene that are either attached to, or contained within any other item that is attached to
more than one task, where the task durations overlap.
The check results are highlighted on the Selection Tree and in the main NavisWorks window.
