Each link requires a link template, which identifies what fields from a table are associated with the links that use that template.
You can select linked records in the data source to automatically select the linked objects in the drawing, and you can select objects to select the linked records in the data source
The Synchronize option analyzes the links in your drawing and detects errors.
You can export information about links to a text file.
