Repair and Recovery
When an error occurs, diagnostic information is recorded in the aclt.err file,
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.
■
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:
Auditing Header
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.
