A link set is a group of links to files, models, references, saved views, and supporting documentation. Link sets can be viewed in the Links tab of the Explorer dialog. The link set's name appears next to the Link Set icon.

A link set can contain links to DGN and DWG files; design, drawing, and sheet models; folders, references, saved views, and drawing boundaries. You can also link to supporting documentation created in other file formats such as:

• Microsoft Word documents, including headings and bookmarks within the documents
• Microsoft Excel workbooks, including specific worksheets within the workbooks
• Adobe PDFs, including bookmarks within the file
• Websites, key-ins, and e-mail addresses
• Folders, link sets and configuration variables
• Any other file type

Each link set is an independent object stored as non-graphical data in a DGN file or in a DGN library (DGNLib). If you move a DGN file with link sets stored in it, the link sets move with the DGN file and retain their links to the target files.

Links in a link set may be organized in folders. Links can also be created for folders in which everything in the folder is linked. To follow a link, double-click it or right-click the link and choose Open from the pop-up menu.

In the Explorer dialog’s Links tab, you can view the information in the link set, including browsing through the link set, adding links to the link set, opening links, adding links to elements, adding links to detailing symbols, and viewing a link's properties.

You can add links to elements either on-the-fly without creating a link set or by selecting a link from the link set and adding it to the element.

Link sets cannot be stored in DWG files.
