Navisworks File Has Expired

[Libby Cowen]

Revuis registered, but a message displays saying the trial is expired when you attempt to use the AutoCAD, Navisworks, Revit, SolidWorks, or SketchUp Pro plugin. If you attempt to register, a message displays reporting the serial number and product key cannot be validated.

With IFC Exporter you can export any file (or parts of large files) that can be opened in Autodesk Navisworks to the IFC format (IFC2x3 or IFC4). When exported, Navisworks model items can be mapped to corresponding IFC objects. This plugin will export both the model geometry and the related data (Property Sets).

The plugin functions in 2 different ways. The straightforward way is to select model items (selection) that you want to export from the Navisworks model and export them without mapping objects. If using this way, all entities in the IFC file are represented as IfcEquipmentElement. The second way is to use object mapping. For this, you need to create a predefined selection or search sets for each different object type in the Navisworks model and tell the plugin which IfcType to use when exporting them.

After installated, the all the word in plug in cannot be seen.

And after exported the IFC file. I am trying to import to Dialux Evo to do the lighting design calculation. But the IFC file is having import to Dialux Evo.

Hi, It may be due to fact that different IFC schema versions may also require little different IFC reader functions.E.g. Navisworks 2025 version have option to use 4 different conversion methods (V1-V4). Please find them in Options Editor -> File Readers -> IFC -> Conversion method. Please note also that using latest schema 4.3 is not yet supported by many viewers and applications.

This is one of the only ways to turn NWCs into IFCs out there. It works great at doing that, however if you have an NWC with many objects, then the file size of the converted IFC can be massive which makes the IFC practically useless in Revit. Really hoping they can compress the file size somehow in the future.

Hi,In licensed version links will be added to IFC properties and it depends on target application or viewer how they are opened. For example in BIMCollab ZOOM there is an "open" command in the context menu for that. In trial version values of the properties have been removed.

Hi Aniket,Trial version starts automatically from installation date and last for 15 days. After that same main version can't be launched in the same computer without a license. Please contact jari.he...@codemill.fi if you have issues with expired trial to get extended trial period.

I use this to export IFC from both Navisworks and AutoCad files. i use 12D Survey Sortware which has IFC importing and exporting, but 12d AutoCad import leaves out a lot of solid detail. Making an IFC fileout of the Navisworks/Autocad file gives better solid details that i can then import, manipulate and export a new IFC file to Trimble Connect. it works and baffles the Engineers who can't do what i do ;-)

I tried using this 3-4 years ago and it worked, but it was very time consuming to create the IFC files, and I had to be very careful about how many objects were selected for conversion or it would fail altogether. I decided to try the 15 day trial again this past August, 2022 and it seems so much smoother and faster now!

Hi, I have an NWF file which I have attached several 3D models from Plant3D (piping and equipments). I wonder if someone knows how to export this file in IFC while maintaining the layers of the objects? When I use IFC exporter and bring it in revit, the XREF stayed in a big block and it's impossible to make a query on one pipe to have the information of that line.

Hi Julie,Unfortunately I am not familiar with correct Revit importing settings, but we have now also Plant3D IFC exporter available.If you are interested in trying it, please find the download link:https:\\www.codemill.fi\download\IFCP3D2022.2.zip

I do not know if it is a problem with the IFC of my computers, but when executing the file it stays in the "saving" option and extracts a file of 4 kb which at the moment of opening it does not show anything, I would appreciate someone to help me.

Hello, you have to choose proper txt options file. -products/troubleshooting/caas/sfdcarticles/sfdcarticles/Revit-IFC-file-not-exported-or-contains-no-objects-after-Revit-interface-language-change.html

That link seems to be related to Revit, not for using Navisworks IFC Exporter plugin. However the most common reason why the IFC file doesn't contain anything is that there aren't selected any model items in the Navisworks before starting the process

Thank you for your comments.Yes it can be used with any files that can be opened into the Navisworks. When Navisworks reads the source file, it will basically creates a triangle mesh of the model. After that the geometry of the model is almost equal between different source formats and can be saved as an IFC file

Thank you for the feedback,Please check that the model / submodels are not transformed / rotated in the Navisworks. Please also check that in File Options -> Orientation that Up vector is 0,0,1 and North vector is 0,1,0If it is possible for you to send us the file, we are pleased to look at it
