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.

Check a TimeLiner Schedule

1. Click Home tab > Tools panel > TimeLiner .

2. In the TimeLiner window > Tasks tab, click Find Items .

   Tip: If this option is not available, open the Options Editor, and click Tools > TimeLiner > Enable Find check box.

3. Select one of the available options:

   • Attached Items. Choose this to select any items in the scene that are directly attached to a task.

   • 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.

   • Unattached/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.

   • Items Attached to Multiple Tasks. Choose this to select any items in the scene that are directly attached to more than one task.

   • 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.

   • 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.

   • 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 Scene View.
