Unable to load this drawing file

By | May 18, 2017

Unable to load this drawing file because it contains inrrect or corrupted information” notification is one of the nightmares for AutoCAD’s users. This file will not open. The reason can due to virus or turn off power. For big project, this problem will cause a great consequence for you. In this article, I will help you to solve above error by AutoCAD’s tools.

1. Check the backup file
By default, AutoCAD will create a backup file when you save a drawing. For example: drawing file is “Foundation.dwg”, backup file is “Foundation.bak”. If AutoCAD do not create a backup file, you can do the following:
Tool> Options> Open and save> Create backup copy with each save.

create backup copy with save

create backup copy with save

2. Use the Recover command
File> Drawing Untilities> Recover, this command allows you to restore almost the full contents of the source file. After typing command, you specify the path to the error file and wait for the program to run. Next, it will tell you how many errors you have fixed and how many common mistakes will be fixed. This will eliminate approximately 60% of the common errors. If this step is successful, you go through step 3.

3. Use the AUDIT and PURGE commands
Type AUDIT command or File> Drawing Untilities> Audit. The program will ask Fix any errors detected? [Yes / No] <N>: You select Y then press Enter. AutoCAD will continue to scan the drawing and correct the errors that the RECOVER command can not fix and you do this several times until AutoCAD can not find it. To ensure then you use the PURGE command (File> Drawing Untilities> Purge) to remove unused references from the drawing (blocks, layers, xref …) because sometimes these references can also cause errors.

4. Use the INSERT command
In fact, sometimes you can use the INSERT command to restore the drawing. Here we see the error file as a block to insert into another drawing. Restarting AutoCAD will create a new drawing, and then type DDINSERT (Draw> Insert> Block) and then delete all the parameters in the new dialog box appeared and mark EXPLODE item and click OK. AutoCAD will try to insert and explode the error file into the current drawing, If this step is successful, you can execute step 3 again.

5. Use Partial OPEN feature
This method ensures a higher success rate but the percentage of drawings being recovered is lower. As you know, AutoCAD splits drawings into layers for easy management and manipulation. When the Open file is corrupted, usually due to some broken layers. AutoCAD allows you to open individual layers. By the Partialopen command (File> Open> Partial Open). If successful, the following window will appear, notice the right pane will display the layers in your drawing, you mark from one layer to another. Repeat Step 3, then Save as to another drawing, and then merge them into one, so that you get rid of the defective layer.

6. WBLOCK to extract the drawing out the block
After performing the PARTIAL OPEN command or RECOVER command, AUDIT command does not work. You can do the following: Select all layers in the drawing: ON, THAWED, and UNLOCKED for later operation that can affect all Both the layers, then type WBLOCK then select the object to extract and name the block and press OK. Close the current file (not SAVE) and then reblock. I have done this operation many times and found very effective.

7. Switch to DXF file
Open the corrupted CAD file and click OK. Immediately press ESC to cancel the first regeneration of the drawing. If open, the message “You may want to practice this process with an undamaged. Next, you type the DXFOUT command and then fill the file into OK and wait a few moments. Then restart CAD to create a new file, type DFXIN to re-open the newly created DFX file, if successful you save that file to DWG is done. Since DXF files are a translation of DWF files into ASCII code, if you do not use Notepad to open DXF files and look for the wrong code (with files of the same type), understand and save and try to open again. lie. This is a very new way I have not had time to study, if you know anything else please contact the editor.

8. Finally
After doing all the way and still not fix the problem, why not try running SCANDISK. A drawing when it is copied onto a floppy disk or hard disk may reside on faulty sectors, SCANDISK will scan the disk surface and repair those fault sectors. The hard disk is there, but the floppies sometimes happen.

The most effective way to prevent these losses is to regularly back up your data. Before you restore a drawing, you make a faulty drawing backup, because during the restore process it may be skewed to the original drawing.
