In AutoCAD, xref is a shortened term for “external references”. As the name indicates, the xref feature allows you to attach external references to your drawing. External references can be in the format of other drawings, PDFs, images, point cloud data, and so on.
In this regard, what is XREF? An XRef is an ‘external reference’ to another AutoCAD drawing file. One file can reference many other files and display them as if they were one. These are used in larger projects for many reasons: They keep the file sizes down. They allow many users to work on individual components of a project.
Beside above, what is a reference in AutoCAD? In AutoCAD, you can import drawings in a way that keeps imported drawings independent of current drawings. This type of file is called an external reference or Xref. The Xref file does not become part of a drawing database and it is loaded simultaneously with other drawings in which it is imported.
People ask also, what is the benefit of using Xrefs? Xrefs are versatile and easy to use for different DWG types, whether they contain a single object or a complete design. Updates to the external drawing appear automatically in the host drawing when the drawing is opened, and notification of updates is provided during the host drawing session.
Similarly, what is the difference between a block and an XREF? Xrefs are drawings that are externally linked to a drawing. As the Xref changes it updates in all the drawings it is attached to. An Xref is really just a block that the definition resides in an external drawing opposed to locally within the host drawing. Many aspects of blocks are identical to an xref.
