How to convert Revit (.rvt,.rfa) to 3D Studio (.3ds)?


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.

     

3D Studio

The .3ds file format was the native file format of the old Autodesk '3D Studio R1-R4' software, which was popular up to about 1996 before its successor (3ds Max) replaced it. The file format is a dated, 16-bit, obsolete format. It is limited to triangle geometry, 65536 polygons per mesh, no vertex normals for accurate smoothing, 8.3 DOS filename naming and a maximum of 10 characters for object names.

Please do not confuse the .3ds format with the 3ds Max .max format. You will find throughout the 3D industry that some companies refer to .3ds as the "3ds Max file format" but this is not true. The native file format of 3ds Max is the .max format, whereas .3ds is just a legacy import/export file format ported over to 3ds Max by Tom Hudson during the transition from 3D Studio R4 back in the early 1990s. DO NOT use the .3ds file format to convert to/from 3ds Max but rather use Okino's dedicated PolyTrans-for-3dsMax plug-in system for 3ds Max.
