Trying to export an i.dgn from ABD U3...
I've noticed that any orphan cells (Ctrl-G) elements will cause problems.
Also had problems with Stair and even Wall elements as well as some SmartSolid extrusions.
Is there a list of workarounds / known problems?
Can you please specify what kind of problem you are facing?
I get this error "Unable to publish business data for element <1716817> of type <2>"
I then have to use "analyze element selectbyid 1716817" to select the problem element and either use Ctrl-U to ungroup the element or Drop the element (Application Elements)
This seems to allow the elements to process, but is of course not a long term solution, especially becauee the dropped elements will lose their business data. This will screw up any downstream BIM workflows like quantification and rules-based clash detection etc.
