How to convert Unigraphics NX (UG NX) to LightWave (.lws,.lwo)?


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.

     

LightWave

LightWave is a well known and respected DCC/Animation system which has been around since the early days of the Amiga. It continues to be developed by Newtek Inc.

Okino implemented the main system to read and write LightWave .lwo and .lws files as of 1993, with the peak demand for our LightWave converters being throughout the 1990s and into the early 2000s, after which other animation systems became more popular (3ds Max, Maya and Softimage).

Fortunately a copy of the LightWave software is not needed to convert to/from the .lws and .lwo formats (as otherwise is the defacto case for the 3ds Max and Maya animation systems). The general scene data is stored in the ASCII .lws scene file whereas the binary .lwo file contains the geometry and material information.
