Accepted File Types


Detect3D and in:Flux can import any of the 8 CAD geometry formats listed below. Geometry files which have already been imported into Detect3D (.d3d) files or in:Flux (.ifx) files can also be chosen when importing geometry to a new project.


Best options:

DGN: Microstation file format, PDMS can export to DGN. SmartPlant can also export to DGN with the Interop Publisher package.

DWG: AutoCAD native file format

DWF: format exported from Navisworks Manage or Navisworks Simulate. Best way from converting from NWD or other CAD formats not listed here.


Also accepted:

DXF: AutoCAD file format for non-AutoCAD applications

IGS: a CAD format based on the Initial Graphics Exchange Specification

STEP: a standardized CAD file format under ISO 10303

OBJ: Triangulated file format used for storing a description of the surface of 3D objects, usually has an associated .mtl (material file), that is used for layers. For the layers to be imported correctly the .mtl file should be in the same directory as the .obj file

STL: Triangulated file format, the simplest 3D CAD file which does not have any layers.


IFX: The geometry model from a saved in:Flux project file (.ifx) may be selected when importing CAD models. Doing so will only load the CAD geometry from the ifx file.


D3D: Similar to above, any saved Detect3D file (.d3d) with geometry can be selected when importing CAD to in:Flux. Doing so will only import the CAD geometry from the selected file into the current in:Flux project.


Other options:

Navisworks is a great platform for importing a wide range of CAD file formats. With the DWF importer fuction, these formats can then be imported into Detect3D or in:Flux. A list of available import formats for Navisworks is available here.


Additionally, there are extensions for unique filetypes like SmartPlant .vue or VUE files (add-on link here). After installing this add-on users can import their .vue files into Navisworks and create DWF files for importing into Detect3D or in:Flux.
