3D objects exported as dwfx files exported from Revit 2017 & Navis 2017 coming in different locations in Synchro2016
3D Models coming in from different software programs may have different coordinate systems.
In your case, I would recommend appending the Revit 2017 file into your Navis 2017 NWF and exporting from there either as dwfx or as .spx using our Navisworks plugin.
A good idea is to use the Navisworks 'hide unselected' feature to export different parts/trades of the model separately.
I would also try first to export from Revit and Navis using our plugins and see if those line up.
Note: spx files are imported to your master file using file > import > synchro project.
