This analysis can include annotation, viewpoints, animations, and reporting. NWF files are comprised only of analysis and comments on the NWD file made by the other participating parties. The NWD file is typically created and governed by the BIM project coordinator. The NWD file is your entire project including all of the model data and all of the analysis.
The NWCįile is really just how Navisworks translates the information that comes into it. In Navisworks there are really only 2 user managed file types NWD and NWF. A NWD can be opened with any Navisworks program, especially Freedom Viewer. This allows the ability to share a project with someone externally without having to send all of the linked/appended files.
Again, to relate it back to AutoCAD…it’s like binding the XREF’s in the sheet file. Typically, you take your project file (NWF) and publish it to NWD…which removes all links and keeps everything in the NWD. NWD – This is the equivalent of a DWF or PDF. Again, this is your project/working file…this is the file you use daily to update info and reload updates from the linked/appended files. The content that is saved in an NWF are things like redlines, saved viewpoints, materials, etc.
Think of it this way (from the world of AutoCAD)…NWF is the sheet file and that sheet file contains a bunch of XREF’s, which are the loaded (appended) files. The NWF contains all of the Navisworks data and pointers to the files that are loaded. If the DWG isn’t newer, then the NWC is used and loads much quicker. When you open a DWG, a NWC is created and is used the next time the Navisworks project is opened unless the DWG is newer. NWC is the format that is typically created (exported) from products like Revit and AutoCAD, and also is created automatically when Navisworks opens up a DWG directly. These files can only be read into Navisworks and Navisworks cannot export out or be saved as a NWC. NWC – This is sometimes also called the Cache file.
