EXTERNAL REFERENCE DRAWINGS (XREF)

The XREF command is used to insert an image of another drawing into the current drawing. AutoCAD calls the host drawing the Parent and the Xref dwg the Child . This command is very similar to the INSERT command. But when you externally reference (XREF) the Child dwg into the Parent dwg, the image of the Child dwg appears but only the path to where the original Child dwg is stored is loaded into the Parent dwg. The Child dwg does not become a permanent part of the Parent dwg.

Each time you open the Parent dwg, it will look for the Child dwg (via the path) and will load the image of the current version of the Child dwg. If the Child dwg has been changed, the new changed version will be displayed. So the Parent dwg will always display the most current version of...
