To link a comment, line, area, CAD file, or model to a specific timeline, follow these steps:
When you create a new comment in SkyView, for example, it automatically gets tagged with the active timeline.
To view an object's association, click on the object in the object list.
Under Timeline, you can see the object's association.
If the object doesn't have a selected tag, you can link one by clicking on the dropdown menu and selecting the timeline to which the object belongs. An object doesn't necessarily have to have a tag and can imply that it belongs to all timelines for the project.
To remove a link, click on the cross icon next to the tag.
