טיפול בקובץ AutoCAD פגום

ראשון, 27 נובמבר 2016
47

קובץ ה AutoCAD שלנו נפגע או פגום ומראה אחד מהתסמינים הבאים:

  • קובץ לא נפתח.
  • קובץ נתקע או גורם לקריסת ה AutoCAD.
  • ביצועים איטיים בעת עריכת הקובץ.
  • הודעת שגיאה בעת פתיחה או בזמן בקובץ.
  • פקודות מסוימות אינן עובדות או יש עיכוב ניכר בתגובה.
  • גודל קובץ ענק ללא הסבר הגיוני.
  • בעיות תצוגה .
  • אלמנטים חסרים מהתכנון.

אין צורך להיבהל, ניתן להתקשר למוקד שירות והתמיכה ב 03-9267957

(רצוי להכין את המספר הסידורי של ה AutoCAD)

בכל אופן הגורמים לבעיות אלו יכולים להיות:

  • יישומי צד שלישי המופעלות ומותקנות בסביבת AutoCAD.
  • קבצי DWG נוצרו או נשמרו על ידי תוכנות שאינן RealDWG.
  • AutoCAD נסגר בעצמו בזמן שמירת השרטוט.
  • שרטוטים ישנים הנמאים בשימוש רב פעמי במהלך שנים.
  • בעיות רשת (שגיאות תקשורת, נעילת קבצים, כתיבה סמויה של נתונים).
  • מדיית אחסון פגומה (סקטורים פגומים בכונן קשיח).
  • בעיות ברכיב זיכרון.
  • בעיות במערכת הפעלה.
  • ברקים ונחשולי מתח.

אז מה עושים? נשתמש בקווים מנחים לטיפול בבעיות אלו.

במקרה שהשרטוט לא נפתח:

Your drawing may show the message "Drawing file is not valid," display a message about errors being found, hang or crash during the open process, or simply may not appear in AutoCAD after you have selected to open it (i.e., you open it but all you ever see is the default "Drawing1.dwg" or another file that you currently have open).

  • Refer to Error: "Drawing file is not valid" when opening a file in AutoCAD if you receive the "Drawing file is not valid" error when opening the DWG file.
  • You might have leftover .dwl or dwl2 files in the folder directory. These are two hidden files that have the same name as the dwg file but with the extensions .dwl and .dwl2. In the Windows Control Panel, go to Folder Options. On the View tab, turn on the option to show hidden files. You can then go back to the folder directory and delete the .dwl and .dwl2 files if they are found alongside your DWG file. Attempt to open the DWG again.

If neither of the above options allow you to open the DWG, move on to the next set of steps. These steps can be tried one at a time. Be sure to stop and try to open the file after each one. If the file opens, there is no need to continue to the rest of the steps.

  1. Open a blank DWG and run the RECOVER command. Select the problematic file. AutoCAD will attempt to recover the file and open it.
  2. Open a blank DWG and run the RECOVERALL command. Select the problematic file. AutoCAD will attempt to recover the file and open it.
  3. Open a blank DWG and run the INSERT command. Select the problematic file and see if it will insert. If it does, then run EXPLODE and select the inserted block. Run AUDIT and PURGE commands, and then use SAVEAS to create a new DWG.
  4. Look in the same directory where the DWG resides and see if there is a BAK file of the same name. If so, rename the BAK extension to DWG and see if the file can then be opened.
  5. Look in C:\Windows\Temp for files with an SV$ extension. If any exist with a similar name to the corrupted DWG file, then rename the extension to DWG and see if it can then be opened.
  6. Go to your backup system and restore the file from a time before it became corrupted.
     

If the drawing file (DWG) still opens:

Perform the following steps in the order listed:

1. Open the drawing file.

2. Purge Registered Applications (from the command line):

  • Type -PURGE.
  • "R" for Regapps (registered applications), then Enter.
  • "N" when asked to verify each name to be purged, then Enter.

3. Type PURGE at the command line. With all checkboxes checked on, click Purge All.

4. Audit and fix any errors:

  • Type AUDIT at the command line.
  • "Y" for Yes to fix any errors, then Enter.

5. Save the drawing.

 

If the drawing persists with problems, try the following steps:

1. Ensure all layers are on, thawed, and unlocked.

2. Detach all external references (XREFs).

3. Write Block all necessary information in the file out to a new drawing (from the command line):

  • Type WBLOCK at the command line.
  • Under Source, select "Objects".
  • Under Objects, click the "Select objects" icon.
  • Use a selection window to choose only the necessary objects from the file (do not simply type ALL).

Set file path and name, then OK.

4. Open a new blank drawing file.

5. Insert the file created in Step 3 (from the command line):

  • Type INSERT at the command line.
  • Select the file.
  • Uncheck "Specify On-screen" and check "Explode", then OK.

6. Type PURGE at the command line. With all checkboxes checked on, click Purge All.

7. AUDIT and fix any errors.

8. Type SAVEAS and create a new file name.

 

Still having problems?

Take the following steps.  They can be done in any order, but have been listed in the order that Autodesk recommends. The file can be checked after each step. If the problem is resolved, you don't need to continue.

  • Open a blank DWG and type RECOVER at the command line. Browse to the problematic file to allow AutoCAD a chance to restore the file.
  • Type OVERKILL at the command line, and select all objects. Check or uncheck properties to include or ignore, then click OK.
  • Type DELCON at the command line, and select all objects.
  • Type BREP and select all objects (if there are solids or surfaces in the file)
  • Type -SCALELISTEDIT, then "R" for reset, then "Y" for yes.
  • Type FILTERS, then click on the 'delete filters' button.
  • The DGNPURGE tool can be run if the file size is unexpectedly very large (see AutoCAD DWG files unexpectedly increase in file size).
  • Try using a different version of AutoCAD to open the drawing, such as AutoCAD 2013 vs. AutoCAD 2015 or plain AutoCAD vs. AutoCAD Architecture, etc. Try different computers if available.
  • Open a blank DWG, and try to attach the problematic file as an XREF. If it allows you to attach the file, try next to BIND it to the current file. If that works, run the repair steps listed above.
  • Use the SAVEAS command to save the DWG in an older file format. Attempt to open the newly created file.
  • ​Export the file to DXF format using the DXFOUT command. Next, open a blank DWG and use the DXFIN command to import the file just created.
  • ​Restore the Layout tabs:
    1. Right-Click one of the default layout tabs
    2. Select 'From Template...'
    3. Open the original file
    4. Choose the layout tabs to restore. (It is recommended to do this one tab at a time, in case one or more layout
    tabs are corrupted)/
  • Move drawing objects between model and paper space. You may find that only one drawing space is usable in your file, although your main concern is model space:
    1. ​​Create a new layout and if need be, create a viewport.
    2. Use CHSPACE to move all the geometry to paper space.
    3. Create a new drawing and use the Design Center (ADC) to move the layout from the damaged file into it.
    4. Use CHSPACE again to move the geometry back to model space.
    5. Restore the original layouts from the bad file using the Design Center.
  • Dissect the drawing. In a copy of the file, conduct a process of elimination using QSELECT to select different object types and then delete them to see if that fixes what is wrong in the file. Do PURGE All after each deletion. Eventually you should remove the problem elements and then you can choose to leave them out, copy them in again from another file, recreate them, or further troubleshoot individual items to pinpoint exactly which one is problematic. A quick start to this whole process is to delete everything in the drawing and then test it. This will quickly tell you if the issue is with a drawing object or if it is a part of the drawing database.​
