External References

autocad_entity:autocad_xref

External References are references to external files, they consist of two parts:

  • External Reference
  • External Reference definition

The External Reference is a feature with point geometry that represents the location where the contents of the external file should be placed. The External Reference definition is much like a block definition but instead of containing geometry the External Reference definition contains information about the type of External Reference and the path to the external file.

There are two types of External Reference; attached, which will include nested External References when viewed in an AutoCAD application and overlaid, which will not include nested External References.
