I have a DGN with linked word/excel/pdf documents and I am wanting to extract the filenames and connect to the relevant geometry within GIS. When I open the DGN in MicroStation I can see the linked documents but when I open in FME Inspector, they disappear. See attached image of links in MicroStation. I thought they may be pulled through into a 'linkage' field but they don't look to be.
Solved
Is it possible to extract linked documents from a DGN into GIS?

Hi @oli2wd,
The file linkage information can be found in the DGNV8 format attributes igds_xattributes{}.fullPath and igds_xattributes{}.fileName. It will take a little text manipulation to get clean file and path names out of these attributes, but this can be done using regular expressions in StringSearcher transformers:
I am attaching a workspace to illustrate the process.

Perhaps the link might be contained in the 'User Linkage' on the point features. Are you able to provide a sample of your DGN file for us to examine? If you do not want to share it publicly, perhaps you could submit a support case with us. Happy FMEing!

Thank you Evie. I will submit it via a support case if someone is able to take a look. Many thanks, Olivia.

This is just what we were looking for. Many thanks for your help.
