How to convert CADMATIC (3DP) to DirectX (.x)?

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.



Cadmatic Oy developers 3D software for the plant and ship building industries.

Okino and Cadmatic have collaborated for many years to create a fluid 3D conversion pipeline from Okino's CAD importers into Cadmatic 3D Plant software. This is achieved through a custom 3D export converter module for Okino software which creates "3DP" files. Such files can then be loaded into Cadmatic's 3D plant design software.

This custom solution allows Cadmatic users to source from all primary MCAD and CAD programs, resulting in highly optimized, clean and robust 3DP files. Commonly requested source MCAD programs include SolidWorks, ProE/Creo, IGES solids, STEP solids, PARASOLID solids, DWF-3D, (for the technically best AutoCAD, NavisWorks, Revit, Inventor conversions) DXF/DWG, JT and basically all other top named MCAD programs.

The 3DP Exporter plug-in for Okino software is developed and maintained by Cadmatic. Please contact them directly to obtain the 3DP installer.

If you wish to convert from the Cadmatic 3D Plant software into other BREP solids modelling programs (such as SolidWorks, Unigraphics NX, Siemens Team Center, ProE/Creo CATIA, etc.) then please contact Cadmatic directly for their speciality methods and processes. Such processes are not provided by Okino software as its requires special processing of data from the 3D Plant software. As examples, Cadmatic 3D Plant can export JT "solids-based" files for Unigraphics NX and Siemens Team Center, while the use of a local copy of AutoCAD allows Cadmatic 3D Plant datasets to be converted into "solids" for Autodesk Inventor and other programs.



.x files are the native 3D file format of the legacy Microsoft DirectX v2/v3 API and 3D toolkit. They were generally associated with 3D gaming whereby low polygon meshes with skinning (deformation) and "animation sets/clips" were the required norm. At the time of its introduction in 1995 there really wasn't any other similar 3D file formats which supported these capabilities in one, well defined and easily accessible format. Direct3D shipped for the first time in the DirectX 2.0 SDK in June 1996

Historically, the DirectX technology was developed a company called Rendermorphics of the UK which Microsoft purchased in February 1995. As little known history, 3 companies in the UK developed advanced realtime rendering toolkits prior to 1995: Argonaut Software (BRender), Criterion Software (RenderWare) and Rendermorphics (Reality Lab). Microsoft was to license the Argonaut 3D toolkit but opted to purchase the entire Rendermorphics company instead, at the last moment. As these various toolkits often sold for $50k at that time, the other two competitors eventually went out of business once Microsoft started giving DirectX away for free.

Okino knows of the .x file format well as it was the first company to properly and fully implement a DirectX importer and exporter, including full support for skinning and animation at a time when no other software provided such conversion support.

The DirectX file format had a long life until some people inside and outside of Microsoft started to push the FBX file format instead.
