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. This makes choosing what you want to see in Navisworks very easy as you can turn off or hide any unwanted objects.Ĭivil Solutions Applications ExpertAs a software applications expert I provides knowledgeable and competent support and training, specializing in AutoCAD, Civil 3D, Infraworks, Advance Steel, ReCap, Pix4D and Leica's suite of point cloud tools including Register 360 and Cyclone Model.This is a common question I get…what’s the difference between the 3 Navisworks file formats - NWC, NWF and NWD? Here’s how I typically explain the differences… The NWC file that is created within Civil 3D will bring over any Civil 3D or AutoCAD objects that are displayed within Civil 3D including XREF’s and data references. Once the NWC file has been saved it can be opened in Navisworks. Instructions for doing so can be found at the following link: If Civil 3D returns an “Unknown Command” first check to see if the exporter has been installed. This will bring up a save dialog box asking where to save the NWC file. There are a couple of different ways to bring your Civil 3D information in to Navisworks. The process for this is fairly straight forward, as long as the exporter is installed. There are times for model coordination that an AutoCAD Civil 3D file needs to be brought in to Navisworks.
