Work on Drawings During Loading
You can work on drawings before they are fully open. This is useful when you
work on large drawings and you want to begin working immediately. To take
advantage of this capability, three conditions are required.
The drawing must have been saved in paper space.
The OPENPARTIAL system variable must be set to 1.
The INDEXCTL system variable must be set to a non-zero value.
When these conditions are met, you can create or modify visible objects, pan
or zoom, turn off or freeze layers, and any other operation that does not require
displaying objects not visible when the drawing was last saved.
NOTE The Quick View feature will not be fully functional during loading under
these conditions.
Resolve Missing References
As you open a drawing, you are notified (messages and task dialog boxes)
when a reference cannot be located. From the References - Unresolved
Reference Files task dialog box, click Update the Location of the Referenced
Files to open the External References palette to make changes to missing
external references.
The following table outlines some of the references that might be missing and
describes how to handle them.
DescriptionMissing Reference Types
Missing external references are the result of AutoCAD
not being able to resolve the last known location of
External references
an xref, raster image, or underlay. To resolve a missing
external reference, locate the file and update its loca-
tion using the External References palette.
For information about resolving missing referenced
files, see
