Open DWG Library error.........

[tgm]

I am having continuing trouble this morning trying to import and AutoCAd .dwg file. I keep getting an 'open library' type of error and nothing will import.

Any issues with dwg import ??

Thanks for the help,

The exact error message along with the version of VW is required.

Note - if the dwg is a 2007, the file will need to be saved to a 2006 file in order to import into VW.

That was it. It was a 2007 file format. Had it resent as a 2004 and it came right in.

How is one supposed to be aware of this as it is not in print anywhere that I can find??

Thanks again,

It's stated in the User's Guide. I've posted the subject in the online help in a few different places on the message board.

If you search in the online help for "DWG" one of the first paragraphs in one of the first articles strictly states supported versions of DWG files.

In other forums, you'd also find that an error type 8 (which I am assuming is the error number you received) means the file is not supported.

There's also a Knowledge Base article regarding this topic.

If you receive a DWG from and are suspicious of the version, refer to this webpage for determining the file version. ?Open? the dwg file with a text file editor and you will see something like:

"AC1018 L L ? ...etc etc"

In this case, the dwg file is a so-called AutoCAD 2004 format drawing (as it format change was introduced with AutoCAD 2004 and was subsequently used in 2005 and 2006

The next change in format occurring with AutoCAD 2007. Quite possible this may end up being referred to as the AutoCAD 2007 format file ? especially if the newly announced AutoCAD 2008 uses the same binary file format
