How to convert PRC (Adobe 3D PDF) 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.

PRC

PRC (Product Representation Compact) is probably one of the least known of 3D CAD file formats yet it forms the underpinning for Adobe Acrobat 3D PDF files. It may be considered the “silent younger brother of the more well known U3D file format”. It has a fairly long but little unknown history.

PRC is primarily used as a 3D file format to embed 3D data within a PDF file. It was originally developed by the TTF Group of France whom were purchased by Adobe in 2006. In 2014 PRC became an ISO published standard.

Okino's PRC geometry import converter reads in native PRC 3D CAD files. It will also extract PRC and U3D files from within any chosen page of an Adobe 3D PDF file. It is an intelligent and well implemented importer for all forms of complex source PRC CAD file data, including the import and processing of 3D mesh and BREP (solids) geometry, assembly hierarchy (incl. intelligent “proto node” handling), materials (with adherence to the PRC father/son inheritance rules), 2D bitmapped texture maps and meta data.

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.
