Hello everyone
In 2025.1 FME Form I can use the Civil 3d reader, to read extended data from a dwg file just fine. Within the reader I just have to make sure the option for “Civil 3D and CAD entities” is on and leave the other settings as default.
The challenge comes on writing extended data. I can write ‘object data’ just fine but I cannot figure out how to write ‘extended data’. The picture below shows where I want to be able to write data to within the Civil 3D interface, from FME. Any insights would be valuable.

Thank you
