Hi All,

I cannot open a drawing which is 99% complete and is worth many thousands of dollars to date, so I need to be able to repair it or open it some how.

I get the following error message. Decompression Error: 105.

The drawing then shuts down so I cannot pack and go or edit it in any way.

How can I open, repair and complete this drawing ? Any suggestion are much appreciated.

Cheers.

With all drawings closed, have you tried the File, Repair option? I don't recall if it helps with decompression errors though. Another thing to try is create a new blank drawing and then try using File Import to import your original file. Might have to get in touch with Datacad's tech support if those options don't work.

Look for a RECOVER_ARCHIVE folder in your DataCAD program folder (i.e. C:\DataCAD 19\RECOVER_ARCHIVE). There may be recovered copies of your drawing in this folder with a DRF extension. There may also be a swap file in the Temporary Files folder (i.e. C:\DataCAD 19\Temporary Files). In the folder where your AEC file resides, there may be copies of your drawing with a DBK, ARF, or ARB extension.

You can send these to help@datacad.com for us to look at.

Thank you all, the DBK file was able to be opened and worked OK. None of the other suggestions worked.

Cheers

You might also consider doing a File/Purge Drawing and then working from the newer drawing or use the File/Savecopy option to create a copy of the working file and do this periodically as another form of backup.
