External  Reference  FilesOverview

The  following  are  Xref  characteristics:

– An external reference file is known as an “Xref”.

– Current drawing contains only a “pointer”, the path and filename, to the Xref.

– The current drawing does not increase much in size when it contains an Xref.

– The Xref is reloaded each time the current drawing is loaded, thus always showing the latest revision   of the  Xref.

– Xrefs  import   their   linetypes,   layers,  text  styles,  dimstyles, v iews,  ucs’s vports,  and  blocks into   their   current  drawing.

– Each Xref named object is prefixed with the xref drawing name and a pipe “|” symbol. (i.e. HOUSE|A-WALL  for  drawing house.dwg  and  layer  a-wall)

– Xdep stands for external reference dependent objects.

– Xref’s layers can be turned on/off in the current drawing.

– Layer zero(0) resides on layer zero(0) of the current drawing.

– Xrefs  can  be  bound to the  current  drawing,   in  which  case they  become  blocks.

Overlay an Xref

Overlays are typically used when you need to view another drawing’s geometry temporarily, but don’t plan to  plot  using  that   data.  In the following illustration, several people are working on drawings referenced by master.dwg. The person working on a.dwg needs to see the work being completed by the person working on b.dwg , but does not want to xref  b.dwg because it would then appear twice in  master.dwg. Instead, the person overlays  b.dwg, which is not included when  a.dwg is referenced by master.dwg.
