CONVERT NWD & NWC TO IFC
WITHOUT NAVISWORKS.
Drop one .nwd or .nwc file and get an IFC4 model back — rendered in the browser before you download it. No Navisworks licence, nothing to install.
NWD / NWC → IFC
ONE FILENOT EVERY MODEL CONVERTS YET. Most do, some still fail. If yours fails you will see why, and we work through the failures one by one. Very large or geometry-heavy models are the usual cause: split those by discipline or area.
Auto-detect reads the unit every Navisworks loader stores with the model (Revit, IFC, AutoCAD/DWG, plant exports), so it is the right choice. On the rare file that has no unit the converter refuses rather than guessing — pick the model's units from the list and convert again.

ABOUT
Navisworks has no IFC export. Veksle fills that gap. Send a .nwd or .nwc and an IFC4 model comes back, with no Navisworks installation and no licence involved anywhere in the process. The model's units come across with it, so there is normally nothing to set.
The output is IFC4 Design Transfer with real classes: elements that carry an IFC class or a Revit category come out as that class — IfcBeam, IfcColumn, IfcSlab, IfcPlate, IfcMember, IfcCovering, and the MEP flow classes for ducts, pipes, fittings, terminals and equipment. Every element keeps its Navisworks property sets as IFC property sets, sits on its building storey, and MEP elements keep their Revit systems. Anything the source never classified becomes an IfcBuildingElementProxy rather than being dropped.
The result is a model you can query — filter by class, read the property sets,
schedule by storey, trace a system — not just look at.
A successful conversion leaves nothing behind: the upload is deleted the moment the converter is done with it, and the generated IFC as soon as your download is served, or within 30 minutes either way. No account is needed.
FREQUENTLY ASKED QUESTIONS
Is Veksle a Navisworks plug-in?
No. It runs in your browser. Nothing is added to Navisworks and nothing is installed on your machine — unlike the other tools in this space, which all load inside Navisworks Manage or Simulate.
Do I need Navisworks installed to convert a file?
No. No Autodesk software and no licence are needed at any stage. A computer that has never run Navisworks converts a file exactly the same way.
Does Navisworks export IFC on its own?
No. It imports and appends IFC, but ships no IFC export in any edition — not Manage, not Simulate, not Freedom. That gap is why Veksle exists.
Which formats does it handle?
.nwd or .nwc in, .ifc out. Element geometry and the properties attached to it both survive the trip.
What is the difference between NWD and NWC?
An NWC is a cache file — the lightweight export Navisworks writes from a native CAD or Revit model. An NWD is a published document holding the whole federated model in one file. Either one converts here.
Which IFC version does the converter produce?
IFC4 Design Transfer. Elements arrive as their real IFC classes (IfcBeam, IfcColumn, IfcSlab, the MEP flow classes and so on) wherever the source carries a class or Revit category, with their Navisworks property sets, storeys and systems. Only unclassified items fall back to IfcBuildingElementProxy.
Which applications open the converted file?
Any openBIM tool — Solibri, BIMcollab, BlenderBIM, usBIM, Navisworks itself, or Revit's IFC link. It suits clash detection, coordination and quantity review, not re-authoring the model.
How large a model can I convert?
Up to 200 MB, one file per conversion, with a 30-minute ceiling on each run. Models with very complex or very large geometry convert more reliably when they are split by discipline or area and converted in parts. Expect the IFC to come back several times bigger than the file you sent — IFC is a text format.
Do I have to set the model units?
Rarely. Every Navisworks loader (Revit, IFC, AutoCAD/DWG, plant exports) stores the model's unit, and auto-detect reads it. Where a file has no unit recorded the converter stops instead of guessing — choose the units and run it again.
Are my files kept on the server?
No. Your file and the IFC it produced are both erased the moment the conversion ends, and no account is needed. A desktop build is available if you would rather the model never left your machine.
