Teigha Library Error on Export - The file could not be opened

Recommended Posts

I'm trying to export from VW 2014 to create a 2012 DWG file and I get a "Teigha Library Error - The file could not be opened".

I have rebooted and only opened Vectorworks and I still get the error.

I also deleted all previous DWG export folders previous exports had produced but were empty.

I'm running Windows 10.

I've even tried copying just the design layer I want to export to a new file, but I still get the error.

 

Can anyone help or point me in the right direction.

I've searched the community board.

The folders have _ (underscore) in the name and the file has , (comma) in the name.

I just tried it again but exporting to my desktop and it worked fine.

I tried it another time but to the directory with the underscore and it worked fine.

So I think it is the deep directory structure that causes the problem.

 

Good one. :-)

Hi @Alan61 and @JimW

 

I just had a session with a user getting this error and discovered a cause that might be as-yet unreported. I'm posting this to add to the (small) list of conditions responsible for this error message: 

 

One of the directories/folders in the file address used a huge number of characters (43). We shortened the name and all file exports worked thereafter.

 

It might be worth noting that when the directory/folder name was long, some Sheet Layers exported successfully sometimes but one Sheet Layer never did. After shortening the directory/folder name they all exported 100% of the time.

If it helps anyone for the future I also had a long filename trying to save to a folder with commas (on a network share) which threw up the Teigha Library error.  After keeping the long filename (48 characters) but switching to a folder without commas on my desktop, it worked fine
