External References Manager
External References Toolbar
Ribbon: Insert – Reference > 
XREFs (External References)
Ribbon: Manage – Palettes > External References
Menu: Insert – 
External References…
Command line: EXTERNALREFERENCES, IMAGES, XR, XREF
The command opens the External References dialog box. It displays all external references contained in the document and manages these references.
The External references palette allows you to perform the following operations with the referenced drawing files:
· Loading/unloading an external reference in the current drawing.
· Binding an external reference to the current drawing.
· Updating an external reference in order to display in the current drawing the latest changes made to the external reference file (without reloading the current drawing).
· Complete removing an external reference insert from the current drawing with all associated data. It is not sufficient to simply remove a reference from the drawing, since such removal would not lead, for example, to removal of layers associated with the external reference. To remove the external reference completely, use the Remove parameter on the External references palette.
· Changing the name of the reference file and its location (path).
· Changing the file type and the format settings of the file of reference to the raster image.
Xrefs selected in the dialog box are automatically selected and highlighted in the drawing. And vice versa: when xref objects are selected in the drawing, their names will be automatically selected in the External references dialog. The ERHIGHLIGHT system variable is responsible for synchronizing highlighting with objects in the drawing. Single and multiple selection is supported (using CTRL and SHIFT):

Change Path Type
|
A path type can be changed to absolute or relative one. Remove Path – it is expedient to remove a path, if the referenced file is located in the same folder as the current drawing. Select New Path – allows you to set a new path for the missing reference. Find and Replace – allows you to find those among the selected xrefs, which use the specified path and replace all references of these path to a new path. Opens the Find and Replace Selected Paths dialog box. |
