Supported Files for Clash

Model Coordination supports 3D models from various file formats for clash detection.

File format Comments
DWG --
IFC (tracked) Includes IFC files exported from AutoCAD (architecture, AutoCAD MEP, and Civil 3D 2018 and onwards), ARCHICAD, Revit, MagiCAD for Revit and AutoCAD, Siemens NX, Strakon, Tekla Structures, and VectorWorks.
NWC (tracked) Includes NWC files exported from Revit or any AutoCAD-based application, including third-party apps.
RVT --

More file types are supported in Model Coordination for model aggregation, but not for clash detection, and can be accessed in Autodesk Navisworks using the Navisworks Coordination Issues Add-in. See the general supported files help topic for more information of these file types.

Note: When exporting NWC files from Revit for use in Model Coordination, turn on the Convert Element Ids option in Revit before exporting. This ensures Model Coordination recognizes that the NWC file is from Revit, and includes it in automated clash detection. See the Revit page topic in the Navisworks help for more information on the Revit file exporter options.
