Sorry for the late reply Corrado, I was trying to get an answer with Support team from AVEVA Spain...
I had some inconsistancies in one database but those elements were not being used in this sheets. I have deleted them... and still did not export.
Also I have copied the project to them... and they were able to export to dxf... but I still can not export.
... Don't know why... This is a big problem to us... Do you have another sugestion?
Best regards, and sorry again for the late reply.
Sorry for the late reply Deva,

Do you have any other suggestion too?
Thank you for your help and again sorry for the late reply...
Best regards!
