I created 2 models in Revit - 1 arch, 1 electrical. They line up just fine in Revit. But today when I created an NWC of each model and brought them into Navis, they didn't line up. I can't figure out why, or how to fix it.
Looking at other posts, I checked that the project basepoint locations are the same in each Revit file. They are. I also checked the Importer to see if I was using Shared or Project Internal Coordinates. I tried it both ways, neither works.
When bringing the files into Navisworks (Manage 2012...from Revit 2012), I tried using open and selecting them both. I tried using Append and selecting the both, then selecting them 1 at a time. No difference.
I'm fairly new to Navis, so I'm open to any ideas.
How was the RVT model setup in the first place? Was "origin to origin" used? If so, then you are right to be confused. If "center to center" was used, then that would be the reason for the problem you are having now. If they are aligned correctly in your RVT file, try Exporting out the NWC with the option to grab links as well. Then you will have just one NWC with both files. Use the NW Appearance Profiler to get the two files to color differently if you so wish.
It was so long ago when I created these files, I don't actually remember, but I would assume I used origin to origin, simply because that's been my default for 15 years of Autocad and "center to center" seems weird to me. Having said that, the project base point in both files is in the same place relative to the building. Doesn't that confirm alignment of some type?
Whatever that issue, I did as you suggested and brought them in as one NWC. That seems to be working out just fine.
It would be nice to understand how this happens, so I can avoid it or manage it more efficiently in the future.
