In TimeLiner tasks can be created in one of the following ways: 
- Manually, one at a time. 
- Automatically, based on object structure in the Selection Tree, or the selection and search sets. 
- Automatically, built from data sources added to TimeLiner. 
Tip: Unlike manual tasks, which need to be attached to geometry in your model, automatic tasks will be attached to the corresponding geometry as soon as they are created.
