Question

I want to extract XFM data from the attached dgn file. I have tried using the Bentley Map V8XFM reader in both FME 2017 & 2018, but am unable to do so. I have exposed the igds_xfm* attributes as well. Is there a way out ?

    Hi @bb,

    I simulated your case in my machine exposing the elements from the reader:

    You can check the attributes in Data Inspector - Table View:

    Attached the Workspace template - workspace-dgn.fmwt

    Thanks,

    Thanks a lot Danilo. But how do i Decode these values ? Also these are non-geometric, I put a GeometryFilter with NULL option checked and segregated the features into with geometry and without geometry. These being non-geometric, should have some key, which relates them to Geometric features.

    I did another workaround and was able to read the data. I attached BinaryEncoder to the reader with Base64 Encodingtype on igds_xattributes{0}.data attribute. Then i connected the output to TextDecoder with Base64 encodingtype and System Default option in Character Encoding. The destination attribute "_decoded" in the inspector table showed me some meaningful data. I wrote the output in a csv file. Will have to format the output. Thanks a lot Danilo.
