Frederik, It is not immediately obvious to me how to attach general purpose attributes to DXF entities in a way that will be useful so I have not yet attempted this. With some guidance something could likely be done. >> There will be further work on this provider.

I think there is ambiguity or at least several different ways of associating what we think of as attribute data. So something can be done with money/time but I'm concerned it won't be as generally useful as it could be. It would also take some investigation to come up with the best method.
