About Repairing Damaged Drawing Files
If a drawing file is damaged, you can recover some or all of the data by using commands
to find and correct errors.
Repair and Recovery
When an error occurs, diagnostic information is recorded in the acad.err file, oracadlt.err file for AutoCAD LT, which you can use to report a problem.
A drawing file is marked as damaged if corrupted data is detected, or if you request
that the drawing be saved after a program failure. If the damage is minor, sometimes
you can repair the drawing simply by opening it. A recovery notification is displayed
while opening drawing files that are damaged and need recovery. You can
- RECOVER Performs an audit on, and attempts to open, any drawing file.
- RECOVERALL Similar to recover, it additionally operates on all nested xrefs. The
results are displayed in the Drawing Recovery Log window.
- AUDIT Finds and corrects errors in the current drawing.
- RECOVERAUTO Controls the display of recovery notifications before or after opening
a damaged drawing file.
Example: Auditing Files
Auditing a file generates a description of problems with a drawing file and recommendations
for correcting them. As you start the audit, you specify whether you want the program
to try to fix the problems it encounters. The report is similar to the following example:
DXF NAME Current Value Validation Default
PDMODE 990 – 2040
UCSFOLLOW 811 or 0
Error found in auditing header variables
4 Blocks audited
Pass 1 4 objects audited
Pass 2 4 objects audited
Total errors found 2 fixed 2
If you chose not to correct the errors, the last statement changes to
Total errors found 2 fixed 0.
The output from a recovery audit is written to an audit log (ADT) file if the AUDITCTL
system variable is set to 1 (On).
Recovery does not necessarily preserve the high-level consistency of the drawing file.
The program extracts as much material as it can from the damaged file.
