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.
To repair a damaged drawing file
1 Click the Application button, and click Drawing Utilities ➤ Recover ➤
Recover.
2 In the Select File dialog box, select a file. Click Open.
After the audit, all objects with errors are placed in the Previous selection
set for easy access. The output from the audit is written to an audit log
(ADT) file if the AUDITCTL system variable is set to 1 (On).
To repair a damaged drawing file due to a system failure
1 If the program encounters a problem and cannot continue, it displays
an error message and, for some errors, an error code. Record the error
code number, save the changes if possible, and exit to the operating
system.
