System Variables
INDEXCTL
Controls whether layer and spatial indexes are created and saved in drawing
files.
XLOADCTL
Turns xref demand-loading on and off, and controls whether it opens the
referenced drawing or a copy.
XLOADPATH
Creates a path for storing temporary copies of demand-loaded xref files.
Unload Xrefs
When a DWG reference (xref) is unloaded from the current drawing, the
drawing opens much faster and uses less memory.
When an xref is unloaded from the current drawing, the drawing opens much
faster and uses less memory. The xref definition is unloaded from the drawing
file, but the pointer to the reference drawing remains. The xref is not displayed,
and nongraphical object information does not appear in the drawing. However,
you can restore all the information by reloading the xref. If XLOADCTL
(demand loading) is set to 1, unloading the drawing unlocks the original file.
You should unload a reference file if it is not needed in the current drawing
session but may be used later for plotting. You can maintain a working list of
unloaded xrefs in the drawing file that you can load as needed.
To unload an xref
1 Click View tab ➤ Palettes panel ➤ External References Palette.
2 In the External References palette, select the reference name you want
to unload.
3 Right-click, and click Unload.
