Tasks Tab
The Tasks tab enables you to create and manage project tasks. It shows all of the tasks in your schedule, listed in a table format. You can use the scroll bars at the right and at the bottom of the tab to move through the task records.
The Task View
The tasks are shown in a multi-column table, which provides some flexibility in how records are displayed. You can:
- Move or resize columns
- Sort column data in ascending or descending order
- Add new user columns to the default column set
The Task Hierarchy
Autodesk Navisworks TimeLiner supports a hierarchical task structure, as imported from a data source, for example Microsoft Project™ (see the Data Sources Tab for more information). The hierarchy can be expanded or contracted by clicking on the plus or minus sign, respectively, to the left of the task.
The Status Icons
Each task has its own status identified by an icon. Two separate bars are drawn for each task, showing planned against actual relationships. The color is used to differentiate the early (blue), on-time (green), late (red), and planned (gray) portions of the task. Dots mark the planned start and end dates.
Placing the mouse pointer over a Status icon shows a tooltip explaining the task status.

The Active Check Box
The check box in the Active column enables you to turn a task on/off. If a task is turned off, then it will not appear in the simulation. For hierarchical tasks, turning off the parent task will automatically turn off all child tasks.
The Context Menus
Right-clicking within the tasks area on the tab, opens a context menu that enables you to work with tasks in your schedule.
- Copy Date/Time - copies date/time values in the selected field. This option is only available when you right-click one of the date fields (for example, Planned Start).Note: Currently, you cannot use the CTRL + C keyboard shortcut to copy date/time values.
- Paste Date/Time - pastes date/time values. To access this option you need to right-click one of the date fields. Also, this option is not available unless a valid date/time has been previously copied.Note: Currently, you cannot use the CTRL + V keyboard shortcut to copy date/time values.
- Enable Planned Dates - Simulate Planned Dates for the selected task. This option is available when you right-click the Planned Start or the Planned End field.
- Enable Actual Dates - Simulate Actual Dates for the selected task. This option is available when you right-click the Actual Start or the Actual End field.
- Dates - Enables you to simulate actual and planned dates for the selected task. If no dates are enabled for the task, then it will not appear in the simulation.
- Add Task - adds a new task to the schedule. This option is available when you right-click in an area of the task view below any current tasks.
- Attach Current Selection - attaches the currently selected items in the scene to the selected tasks.
- Attach Current Search - attaches all items selected by the current Search to the selected tasks. See Find Objects for more information on searching.
- Attach Set - attaches all items contained within a Selection Set, to the selected tasks. When you choose this option a list of all Selection and Search Sets saved in the current scene is displayed. Choose the Selection or Search Set you wish to attach to the tasks. See Create and Use Sets of Objects Use Sets of Objects for more information on using Selection and Search Sets.
- Append Current Selection - appends the currently selected items in the scene to the items already attached to the selected tasks.Note: See Select Objects for more information on how to select items in Autodesk Navisworks.
- Clear Attachment - removes the attachment from this task.
- Add Comment - adds a comment to the task. See Use Comments, Markups, and Tags View Comments and Annotations for more information.
- Fill Down - sets the Task Type of all currently selected tasks in the Tasks view to match that of the task that is currently 'in focus'.
- Insert Task - inserts a new task above the one currently selected in the Task view.
- Delete Task - deletes the task currently selected in the Task view.
- Auto-Add Tasks - automatically adds a task for every topmost layer, top-most item, or every search and selection set.
- Find - finds items in a schedule based on the search criteria that you select in the Find menu. This option can be turned on/off in the Options Editor (Tools > TimeLiner > Enable Find check box).
You can use multi-selection (i.e. holding down SHIFT or CTRL) to perform most commands on several tasks at once. For example, should you need to delete all tasks, select the first task, then hold down SHIFT and select the last task, then press Delete.

The Gantt Chart View
The Gantt Chart displays a colored bar chart illustrating your project status. Each task takes up one row. The horizontal axis represents the time span of the project, broken down into increments (such as days, weeks, months, and years) and the vertical axis represents the project tasks. Tasks can run sequentially, in parallel, or overlapping.
You can drag a task to different dates, or click and drag on either end of the task to extend or shorten its duration. Any changes are automatically updated in the Task view.
