Could you tell me if you have experience with export to DXF format from .NET
2005 C#. I tried library "DXF Export .NET" from "Soft Gold" firm, but this
software cannot save every objects attributes (like web link). Thank for
your answer. Daniel Bierza
I've recently released as open-source a DXF library that I used for an internal project. I don't remember if it supports web link attributes but you might find it useful. It's available at git http://github.com/cos/dxflibrary.
