*.shp Reference Attachments in ORLD?

Hi,

I'm trying to use shapefiles with a *.dgn as reference attachments. I've managed to get them to work in Microstation (V8i SS3 as well as CE), but ORLD does not appear to recognize the contents of these same shapefiles when opening the same *.dgn.

Has anyone worked with shapefiles in ORLD?

I'm on Windows 10 and running ORLD v.10.03.00.43

Thank you,

-Karl
