How to convert DWG (AutoCAD, DXF) 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.

DWG

DXF and DWG are the native file formats of the Autodesk AutoCAD product since 1982. DWG is the binary file variation to the ASCII DXF file format. These files can be viewed by many programs including Autodesk's free DWG TrueView application. It is a closed file format but has been documented by the Open Design Alliance.

At Okino we consider DXF/DWG to be one of the worst 3D file formats when translating 3D model data between applications (depending on its contents). There is very little understanding about this in the 3D graphics world. As outlined in our "CAD Data Sourcing Suggestons and Rules" page you should ideally use the DWF-3D file format when sourcing from either AutoCAD, Navisworks, Revit and optionally Autodesk Inventor.

Due to deep history, Autodesk software can embed ACIS SAT "BREP solids" data in some of its DXF/DWG files. This is the ideal case as the "BREP solids" geometry definitions lead to cleaner and higher fidelity MCAD file conversions. But even so, it would generally be a safer bet to use a STEP AP214 or "IGES BREP solids" file in such cases.

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.
