You can attach
an entire drawing to the current drawing as a referenced drawing
(xref). With xrefs, changes made in the
referenced drawing are reflected in the current drawing. Attached
xrefs are linked to, but not actually inserted in, another drawing.
Therefore, with xrefs you can build drawings without significantly
increasing the drawing file size.
By using
referenced drawings, you can
Coordinate your work with the work of others by referencing
other drawings in your drawing to keep up with the changes being
made by other designers. You can also assemble a master drawing
from component drawings that may undergo changes as a project
develops.
Ensure that the most recent version of the referenced drawing
is displayed. When you open your drawing, each referenced drawing
is automatically reloaded, so it reflects the latest state of the
referenced drawing file.
Keep the names of layers, dimensioning styles, text styles, and
other named elements in your drawing separate from those in
referenced drawings.
Merge (bind) attached referenced drawings permanently with your
current drawing when the project is complete and ready to be
archived.
NoteLike a block
reference, an xref appears in the current drawing as a single
object. However, you cannot explode an xref without binding it
first.
