Failed SmartSolid, Failed Cell

Hello, I am having trouble opening a MicroStation DGN file with NavisWorks. The problem is that complex solids are not brought into NavisWorks. They are simply omited when I open the DGN file. I know that elements are omitted because I can go to View > Scene Statistics and it tells me that there are failed smartsolids and cells. I get a description as shown below. I usually locate the offending elements and drop them to surfaces, and that seems to fix the problem. It is a real pain to try and located those elements. It's a trial and error process to look for elements that are complex and guess that they are the elements that fail. My question is how can I locate the omitted elements easily? I might expect NavisWorks to create a log file showing the location or element ID's of the failed elements, but I cannot find any such file. Any recommendations? Thanks.

If you have access to Microstation, the best way of bringing DGN files into Navisworks is to export from Microstation as an NWC using the Microstation export plugin. The Microstation export plugin has access to the Microstation API and is able to handle complex elements that the reader has trouble with.

You can do a DGN to NWC conversion using Microstation via the command line, so the process can be automated. Navisworks comes with a sample perl script for converting a whole directory of DGNs.

There is no additional logging for the DGN reader that will show the location or element IDs of failed elements.

That worked. Thanks! For others benefit, here is what I did. I opened MicroStation and loaded the NavisWorks export plugin using the keyin "mdl load nwexport6". Then keyin "nwdout" or "nwcout". You will then export the NavisWorks file from within MicroStation.
