Link OLE Objects in Drawings
When you link information from another document in a drawing, the information can be updated when it changes in the source document.
You can link information from a document created by another application to a drawing. For example, you might want to insert a schedule that will be automatically updated. You can also install multimedia icons that are activated when double-clicked.
Links can be set to be updated either automatically or manually when information in the linked document changes. By default, links are updated automatically. Use OLELINKS to specify automatic or manual updating.
Because a link references the location of the linked document, you need to reconnect the link if the document changes location or is renamed.
Breaking a link does not remove the inserted information from the drawing. Instead, it removes the connection to the linked document. You can break a link when you no longer need to update the information.
