I have a number of files to process for this project, and so I'm using the DWFx export feature in Revit (because I can export in batches). The files are all linked in to a Revit file, and I'm sorting out the pieces I need with view templates. The Revit side works great, and the Navis side was, too, for awhile. One of my co-workers was using these files before the same way (except without the export batches) and it was working fine. I could clash between layers in the various DWFx files, everything was great. Then I clicked on "write report" and NW crashed. Now I can't even run a test between the DWFx files. Any ideas about what's going on?
It looks like you submitted an error report to us when you crashed the first time. Based on that, I can see that this appears to have been an issue that the development team was investigating and resolved in the 2014 release of Navisworks. It looks like your Subscription account includes Navisworks 2014, correct? If so, could you try testing in that version and see if the same behavior occurs?
