How to convert PRC (Adobe 3D PDF) to Softimage|XSI (.xsi)?

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.

Softimage|XSI

Softimage|3D and Softimage|XSI were two well known 3D animation systems written by Softimage Inc. of Montreal Canada. Autodesk eventually came to buy the company in 2008 and then kill off the software in 2014.

Okino had a very long standing relationship with Softimage and its software, having written the main import/export converters for both Softimage|3D and Softimage|XSI in the 1990s.

Conversion to/from Softimage|3D was done with the .hrc and .dsc file formats which are now considered obsolete. In simple terms, you would need to get a running version of Softimage|XSI v7.x on your Windows machine in order to read in older .hrc and .dsc files.

Conversion to/from Softimage|XSI was done with the .xsi v3 and v5 file formats which are still supported in Okino software.
