How to convert Unigraphics NX (UG NX) to 3MF?

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.


Unigraphics NX

Unigraphics NX, or just "NX" is a BREP solids modelling software package with roots that go back to the early 1980s. In 2002 the prior Unigraphics and I-DEAS software packages were merged to create the next generation of solids modelling software called just "NX".

In terms of Okino sales, UG NX comes in within the top 3 of most requested MCAD solids modelling file conversions, along with SolidWorks and ProEngineer/Creo, even if they all focus on slightly different markets.

In simple terms, the best and most reliable way to transfer data from UG NX to Okino software is with the STEP AP214 file format. Other methods include JT files and Parasolid files.



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 Consortiumís web site.

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