XLOADCTL (System Variable)

Turns xref demand-loading on and off, and controls whether it opens the referenced drawing or a copy.

Type: Integer
Saved in: Registry
Initial value: 2




Turns off demand-loading; the entire drawing is loaded.


Turns on demand-loading. Referenced drawings are kept open and locked.


Turns on demand-loading. Copies of referenced drawings are opened and locked; referenced drawings are not locked

When XLOADCTL is set to 2, a copy of each referenced drawing file is stored in the folder specified by the XLOADPATH system variable or the temporary files folder (set in the Options dialog box).

Additionally, xrefs load faster when you work across a network: the performance enhancement is most pronounced when you open drawings with many xrefs.
