Navisworks File Types


Navisworks has three native file types and it can be confusing as to what file type to utilize.

NWD: This file type contains all model geometry, review markups, viewpoints, Misspelled Wordetc are stored in the file. All NWD files are static, meaning they never change since there are no links to external files. .NWD files are typically the file type that is used to share models with other project participants..
NWF (Misspelled WordNavisworks File Set): This file type contains references to all the linked project files, as well as review markups. This is typically your master model file and where you link in all other models that pertain to your project. No model geometry is saved in the NWF, resulting in a small file size.

NWC (Misspelled WordNavisworks Cache File): When you open, merge or append a file create in another program like AutoCAD or Revit into Misspelled WordNavisworks, a cache file created in the same directory as the original native file. The next time that you open that same model, it will load much faster since it is now reading the information from the NMisspelled Wordavisworks cache file rather than the model itself. If the original model file isn’t newer than the cache file, it will re-cache and replace the older one. This process occurs for each file Misspelled WordNavisworks opens or merges natively.

Navisworks 2018 Database Link w/ Excel - Primer

For this demo, I am going to use the Gatehouse sample file that ships with Navisworks 2018. You can find the files C:\Program Files\Autodesk\Navisworks Manage 2018\Samples\Gatehouse\. If you have a newer or older version of Navisworks, the process basically works the same. The Process In order to connect an external data source such as an Excel spreadsheet or an Access database to a Navisworks model, we need to configure a DataTools within Navisworks. We will then be configuring the database connection. When working with the DataTools in Navisworks, there are a few very important rules to keep in mind. If you are using a 32-bit workstation, then you need to utilize the 32-bit ODBC drivers. 64-bit workstations need to utilize 64-bit ODBC drivers. It is also important to note, that the link to Navisworks is one way. Data can be linked and viewed inside of Navisworks, but the data can’t be updated within Navisworks. My workstations are all Windows 10 64-bit workstations. My PC’s are using

Navisworks - Multiple Iterations and Locked Files

Image
While working in Navisworks and you find that you are updating your models frequently, you have probably ran into the issue of having to close your Navisworks model in order to update your appended model. There is a quick way to get around this. In the Options Editor >  Model   > Performance , make sure “Close NWC/NWD Files on Load” is checked. This will now allow you to overwrite NWC files without unloading them in your NWF file. So when you have an updated NWC that has overwritten the existing file, you just need to refresh Navisworks for the new model(s) to load.
