Hi,

I have a dgn file created from OpenBuildings. Within OpenBuildings you can see attributes attached. However, they only seem to show in OpenBuildings not Microsation or FME (i.e they are not tags or xrecords). Therefore, the attribute data must not be stored as tags or xrecords. Does anyone know how attribute data is stored within OpenBuildings application and how fme can read them? Ta

Hi ​@couch,

I’m not too familiar with OpenBuildings, but could your attributes be stored in DGN as item types? There’s a parameter in the DGN V8 Reader you could try under Attribute Options called Read XAttributes and Item Type attributes (V8 Only). (This article has screenshots of the parameter).

I don’t have high expectations though if the attributes aren’t viewable in MicroStation, unfortunately. If you’d like to share a sample file and point out an attribute and element to look for, I’d be happy to take a closer look as well.
