Navisworks and DWF Files

 

In 2019 Insight Numerics released an update for importing DWF files into Detect3D. This DWF file can be exported from Navisworks Manage or Navisworks Simulate software. Since Navisworks can import a large variety of CAD formats (including NWD and NWC files) it greatly reduces time spent for conversions.

 

To create a dwf file:

  1. Load your CAD model into Navisworks Manage or Navisworks Simulate

  2. Click the main menu "N" button on the upper left corner of the screen and choose the Export option

  3. Select "3D DWF/DWFs" as the format and choose a directory to save the file

  4. Once exported, open Detect3D or in:Flux and choose the saved DWF file

  5. When the CAD Import Options window appears, ensure that 'meters' is selected - this will match the scaling and coordinates from Navisworks

  6. Click the Import button

Dividing Up CAD models in Navisworks

On occasion, clients provide the entire site CAD model for F&G mapping analysis. These files can have sites larger than 1 km in length or with multiple complex offshore decks. Depending on your machine, these files may make it difficult for computers to process the file. Fortunately, Navisworks can also be used to help manage these larger complex CAD files.

 

After importing your CAD geometry into Navisworks Manage or Navisworks Simulate, you can select individual layers or equipment pieces from the ‘Selection Tree’ or highlight sections with the ‘Select Box’ tool, shown below.

Once desired items have been selected, from the 'Selection Tree' right-click on the blue selected items and choose “Hide Unselected”

Now export the file to DWF using the same steps above, this time only the selected items will be exported. This process can be repeated by un-hiding and re-hiding CAD pieces.
