I'm trying to figure out how to extract attribute data from my drawing but it seems something's going wrong.

I'm using a template file that works with autocad but seems that DraftSight is unable to open the file.

The message says: "The file "tracciatura.txt" wasn't opened"

And here is the template file(not sure if you can download it):

If the file isn't downloadable here is the content:

===Content beginning===

BL:NAME C010000

BL:X N010000

BL:Y N010000

UFFICIO C020000

===Content end===

Important: in Autocad is needed an empty line at the end

Where's the problem?
