Hi @iew,
In the reader parameters, have you tried checking off "Read Tags Attributes"?
Also, have you seen this article on Reading Tags? This may help you if you havent seen it yet. If you are still experiencing problems, would you be able to share your DGN file and your workspace? If you can't do it here, would you mind submitting a support ticket. Thanks!
Andrea
Thanks for your reply. I had looked at the article you suggested and tried to follow it, but no joy. I have also played around with the reader parameters but still no tags coming through. This makes me wonder if its more to do with how the DGN is actually structured, how the TAGs have been generated. I am not sure they have been assigned to an element/feature in a way FME requires to see them. Is there any way you can clarify exactly what FME is expecting from this perspective please?

The
documentation goes over how tags are represented and read. Most relevant in understanding how tags are read in to FME:
"FME will read the tag set elements and then the tag set definitions. Then as it reads each graphical element from the design file, it uses the element association ID to reconnect the data and attribute names with the graphical element. All the tag data values are then added to the feature returned into FME."
Also keep in mind that if there are "null" tags, these will not be read in. Perhaps trying to expose the attribute "igds_tag_names{}" with the AttributeExposer, will allow you to see a list of tag names (if FME is reading them).
Following up on this older forum post in case any other users encounter a similar sounding issue when trying to read DGN tags.
The issue that @iew encountered with a particular DGN is because the tags are not associated with an element. We currently are only able to read tag information that is associated with an element, this is also described in our documentation here.
We have an existing request to add support to read unassociated tag information (internal reference number: FMEENGINE-10364 ). We will update this post when the issue has been addressed.
