The following appears when exporting a DGN file from AutoPIPE:
---------------------------
---------------------------Exception: Could not export to dgn format---------------------------OK ---------------------------
Why, and how to avoid/
There has only been one documented case where this message has appeared. The problem was directly related to 2 node points having the exact same name. After locating, renaming 1 of the node points to different name the model was exported without issue to a *.DGN file.
Export AutoPIPE *.DGN model
