When working with Naviworks design models, first decide whether to use iModel Connections or SYNCHRO 4D Pro importers. If you choose to use the 4D Pro importers, the RVT files will need to be exported to an SPX file through the SYNCHRO Plugin for Revit, or to DWF or DWFx files which can be later imported into SYNCHRO. Below are directions for using the plugin
SYNCHRO provides a plug-in to export SPX files directly from Navisworks. When exporting from Navisworks to DWF, object GUIDs are not maintained and therefore updated files cannot be synchronised successfully (Resource assignments to Tasks will be lost!) - therefore, it is strongly recommended to use the plug-in when working with Navisworks files.
First when exporting from Navisworks, always use an nwc or nwf file because these can be refreshed later on. If you export from an nwd, you will not be able to synchronize from a refreshed model, so you’ll have to regenerate an nwd, and the object IDs will be different, so you won’t be able to ‘synchronize from’ successfully.
It is important that Explode objects, Optimize for Synchronization, and Generate UIDs for New 3D Objects should be enabled. This will code a new property (parameter) called SynchroID in the elements of your model which make future synchronizations possible. That’s also why you will have to save the Navisworks file after export, and then refresh and export form that same file when the model changes and needs to be synchronized.
3. Select Export SYNCHRO Project, then Browse to Save As an SPX file containing the 3D geometry (and Resources, User Fields, and Tasks if applicable).
4. When export is complete you will recieve this dialog:
5. Save the Navisworks (.nwc or .nwf) file. Make further updates to the same file in order to synchronise from it in the future
6. The exported SPX can be imported into a new or existing "master" project
