Is the drawing encrypted or digitally signed?

Tony - Thanks for your reply.

The drawing doesnt appear to be digitaly signed, the digital signature dialog box doesnt open up and I have it set to display in the options, but the drawing has been created in microstation and I get the following message in the command line :

Non Autodesk DWG. This DWG file was saved by a software application that was
not developed or licensed by Autodesk. Autodesk cannot guarantee the
application compatibility or integrity of this file.

Well, it could be that Mr. Bass has decided to do something
to AutoCAD 2011 that could become a problem for Autodesk.

Can you post the file or email it to me?

Hi Tony, here is the problem dwg file

[Anonymous]

This could be an API change.

Can you post the code that opens the document?

Hi Tony
Here is the code that opens the drawing attached

Try changing the call to open to this:

acadApp.Documents.Open( filename, True, Type.Missing )

Hi Tony

I still get exactly the same error.

[Anonymous]

Do you get the same error with other files, or just
this one?

Do you run the code from an external application (exe) or inside AutoCAD
("netload" it into AutoCAD)?

Hi Norman

The code is run from within autocad (acad 2011).

Thanks Peter

Hi Tony

This is another drawing (saved as a dwg from microstation) gives the same problem

I have actually fixed this problem, it seems to have been a lisp file that I had in my startup suite contents that caused the error, still not really sure why but my .net macro now works on all drawings it open up. Thanks for your help in trying to solve this problem.

I am running into this same problem.  I tried the COM Interop example that Tony Tanzillo gave but it still throws that error when I try to open it.  My file was generated by a third-party tool as well.

[Aaron.Warnke]

I'm having the same problem too.  Seem to only happen with dwg files created from something other than autodesk products.  Drawings open fine directly through AutoCAD (2011), but noth with vba.  Also works fine with 2010. 

[Anonymous]

I ended up using a workaround for the problem.  The operation that I needed to do did NOT require opening the drawing so I just opened it using Database.ReadDwgFile.  It didn't throw any exceptions by doing it this way.

[Aaron.Warnke]

Thanks for the quick reply,  but I need to open the drawing. I wonder why it is different between 2010 and 2011?

[hgasty1001]

This problem is related to the DWGCHECK system variable, set it to 2 , the default is 1, this problem also apears in VBA but with a different error message, something like "Filer error" , but the "solution" is the same set DWGCHECK=2.

It works!

Thanks alot Gaston!
