- Because xrefs are display-only, they provide no access to object data, such as surface elevations or alignment length. For example, you cannot create a surface profile from a surface in an xref. Both data shortcuts and Vault object references provide access to object data.
- Xrefs provide no inherent security. Anyone can break links by moving or renaming referenced files.
- When a Vault DWG contains an xref, you must perform all Xref Manager user operations in the parent DWG, not the xref DWG.
