yes, changing the codec to iso-8859-15 has cleared any error messages, but when i am returned to the model, there is nothing there… sorry, i am a real novice with this program.
Blender handles CAD data of its own:
look at manual page on blender wiki (link is associated to the importer).
Then navigate to documentation of old importer version (2.49) - there are even more details about DXF code in Blender.
If you need more help you can contact me directly per email.
cheers,
