How to convert Rhino (.3dm) to 3KO (NGRAIN .3ko)?

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.

Rhino

The '.3dm' file format, otherwise known as 'OpenNURBS', is the primary and native file format of the Rhino NURBS modeling package by Robert McNeel and Associates.

Okino was one of the earliest companies to recognize and support the McNeel Rhino software. We have natively supported the Rhino .3dm file format since the release of Rhino v2.0 and up to the current versions of the .3dm file format.

Okino also supports many of the other CAD and non-CAD file formats that Rhino can import and export.

3KO

'3KO' is a 3D voxel/mesh visualization file format designed by NGRAIN Corporation of Canada (previously known as i3Dimensions). It was used with their interactive 3D training solutions for the aerospace, defense, and manufacturing sectors. It is generally a "one way" format from such software packages as 3ds Max and Maya into the NGRAIN software.

Going back in time to the 2003 era, Okino and NGRAIN collaborated on the development of the NGRAIN 3KO exporter within Okino software.
