Using RayCAD with Navisworks: retag after every clash round
Navisworks finds the clashes. Fixing them moves ducts and pipes in Revit, and their tags go stale. RayCAD is a Revit plugin that retags what moved, to your firm's standard.
We make RayCAD. Facts about Navisworks come from its public pages, listed under Sources.
On this page
Navisworks is Autodesk's software for reviewing a federated model and finding clashes before construction. It is not a tagging tool, and RayCAD is not a clash tool: they sit at different steps of the same job. RayCAD is a Revit plugin that tags MEPF sheets the way your firm draws them.
It tags HVAC and piping now (ducts, flex ducts, fittings, air terminals, mechanical equipment, fabrication ductwork, pipes, pipe fittings, and pipe accessories), with electrical and fire protection coming soon.
Where Navisworks meets tagging
A clash round ends with a list of fixes: drop this duct 150 mm, reroute that pipe around the beam. The fixes happen in Revit, and every element that moves leaves its tags behind. Elevation tags now show the old height, size tags float off the duct, and some tags end up on top of each other. Someone has to find them all and fix them before the sheets go out again.
The workflow
- Run clashes in Navisworks on the federated model and agree the fixes.
- Make the fixes in Revit. Move and reroute the ducts and pipes.
- Select what moved and run Retag. RayCAD removes the old tags on those elements and places new ones that match the current model. The rest of the sheet stays as it was. See faster turnaround.
- Check Review Tags. It lists anything RayCAD could not place, with the reason. See fewer RFIs.
- Issue the sheets, and export the model to Navisworks for the next round.
What RayCAD does and doesn't do with Navisworks
- RayCAD has no Navisworks add-in and does not read clash reports.
- RayCAD does not find or fix clashes, and it does not move model elements.
- RayCAD places normal Revit tags with your own tag families. Anything Revit exports, such as PDF and DWG sheets, carries them.
For how to update tags by hand after model changes, see updating tags after model changes.

Frequently asked questions
Does RayCAD integrate with Navisworks?
No. RayCAD has no Navisworks add-in or link. It runs in Revit. You find clashes in Navisworks, fix them in Revit, and retag there with RayCAD.
Does RayCAD do clash detection?
No. Clash detection stays in Navisworks. RayCAD tags the drawings once the fixes are in the Revit model.
Do RayCAD tags show up in Navisworks?
Navisworks reviews the 3D model. Tags are 2D annotation in Revit views, so they belong to the sheets, not the coordination model.
Which trades does RayCAD tag today?
HVAC and piping. Electrical and fire protection are being added next.
