How to convert Revit (.rvt,.rfa) to OpenFlight (.flt)?

PolyTrans|CAD+DCC performs mathematically precise CAD, DCC/Animation, GIS and BIM 3D file conversions into all key downstream 3D packages and file formats. Okino software is used and trusted throughout the world by many tens of thousands of 3D professionals in mission & production critical environments, backed by respectable personal support directly from our core development team.

Revit

Autodesk Revit is a building information modelling software tool for architects, landscape architects, structural engineers, mechanical, electrical, and plumbing (MEP) engineers, designers and contractors. The software allows users to design a building and structure and its components in 3D, annotate the model with 2D drafting elements, and access building information from the building model's database.

Revit is a key and core product from which Okino customers often receive and/or coordinate their data files. At Okino we have spent the good part of 2 decades writing our DWF-3D importer specifically to import large, textured files from Revit models.

Note: you would ideally pre-center the model at the origin and pre-scale the model to be of a "sane size" within Revit before exporting the DWF-3D file for Okino software consumption. This will ensure that the model displays properly in your final destination 3D software.

OpenFlight

OpenFlight is an industry standard realtime 3D scene description format developed, owned and maintained by Presagis, Inc. OpenFlight is the most widely used file format for visual simulation databases and is supported by dozens of vendors of realtime 3D tools. Military visual simulation includes battle simulation, fighter jet flight simulation, tank simulation. Visual simulation also includes geospecific terrain for accurate realtime fly through of regions of the planet.

In visual simulation, OpenFlight is the defacto standard format. OpenFlight is also prevalent in the PC animation and modeling communities for optimizing and tagging 3D data for realtime playback. As application examples, in the visual simulation industry OpenFlight is the format for entire worlds. In the entertainment industry it is widely used for level building in realtime games and in the AES or urban simulation industries it is used to organize and optimize scenes for realtime walkthroughs.
