How to convert 3MF 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.

3MF

3MF, 3D Manufacturing Format, is a modern replacement for the legacy STL (StereoLithography) file format with an explicit focus on the proper transmission of CAD and non-CAD model data for 3D printing as well as to downstream services and platforms. From Okino's long term perspective, the VRML2 file format was and is "just as good" for such requirements but never had the correct understanding nor traction since its introduction in 1995.

Features of 3MF over the legacy STL format includes: geometry instancing support, layered texture maps, multiple layers of UV texture coordinates, vertex colors and extended material types.

History, features, overviews, implementation partners and more can be read on the 3MF Consortium’s web site.

Note: Microsoft Windows uses the 3D Manufacturing Format (.3mf) for all 3D printing tasks.

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.
