To attach multiple tasks to a current selection
1 If the TimeLiner window is not already open, click Tools ➤ TimeLiner.
2 Select the desired geometry objects in the Scene Area, or on the Selection Tree.
3 In the TimeLiner window, the Tasks tab, hold the CTRL or SHIFT key to select all required tasks.
4 Right-click the task selection, and click Attach Selection on the shortcut menu.
The task icons have changed indicating that the selected tasks now contain attached items. Look under the
Attached column to get information on the attachment type.
NOTE If you need to add additional items to already attached tasks, click the Append Selection option on the
shortcut menu, otherwise any previous task attachments will be overridden.
Use Rules to Attach Tasks
Attaching tasks manually could take a long time. It is a good practice to either user task names, which correspond
to Selection Tree layers, or create selection and search sets that correspond to the task names. If this is the case,
then you can apply predefined and custom-made rules to instantly attach tasks to objects in the model.
Predefined Rules
■ Items By Task Name. Choose this rule to attach each geometry item in the model to each task with the same
name in the specified column. The default is to use the Task Name column.
■ Selection Sets By Task Name. Choose this rule to attach each Selection and Search Set in the model to each
task with the same name in the specified column. The default is to use the Task Name column.
■ Layers By Task Name. Choose this rule to attach each layer in the model to each task with the same name
in the specified column. The default is to use the Task Name column.
■ Attach Items to Task by Category/Property. Choose this rule to attach each item in the model with the defined
property, to each task with the same name in the specified column. The default is to use the Task Name
column; however, you will also need to define the <category> and <property> values.
To add custom TimeLiner rules
1 From the Rules tab of the TimeLiner window, click the New button.
The Rules Editor dialog is displayed.
2 Enter a new name for your rule in the Rule name box.
