VDA-FS Reader

The VDA-FS Reader provides full access to the Assembly, B-rep and View & PMI Data stored within a particular VDA-FS file. A file does not need to have a particular extension to be read correctly by HOOPS Exchange however the file extensions of VDA-FS files that you can expect to be loaded by HOOPS Exchange are:

  • .VDA

Our readers are updated to the latest released version within 90 days of the release of the authoring software. You can see the exact version supported in the current release here.


Datum planes and construction geometry are also supported and accessed through the assembly tree. Incremental load is not supported by our VDA-FS reader.


The VDA-FS B-rep is pretty simple and only supports geometry in NURBS form. The only types of surface and curve geometry that can be found in a VDA-FS B-rep is:

  • B-spline curve

  • B-spline surface

  • Circular curve


This visualization data for this format is generated by the HOOPS Exchange tessellation engine.
