How to convert Intergraph PDS to 3MF?

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.

Intergraph PDS

Intergraph 'Plant Design System' is a comprehensive, intelligent computer-aided design/engineering (CAD/CAE) application for plant design, construction, and operations.

Files can be exported from PDS as MicroStation DGN files and imported natively into Okino software via our dedicated DGN importer. Preferably, you should import only the .DRI (Design Review) file which itself will then read in all of the individual DGN files. Please follow the method as outlined in the 'How to Import from Intergraph PDS DGN Models' section of the Okino online DGN help file. It is also suggested that you read the 'Tutorial: How to Import Massive DGN Files (PDMS Plants, Oil Refineries, etc)' section of the same help page.

3MF

3MF, 3D Manufacturing Format, is a modern replacement for the legacy STL (StereoLithography) file format with an explicit focus on the proper transmission of CAD and non-CAD model data for 3D printing as well as to downstream services and platforms. From Okino's long term perspective, the VRML2 file format was and is "just as good" for such requirements but never had the correct understanding nor traction since its introduction in 1995.

Features of 3MF over the legacy STL format includes: geometry instancing support, layered texture maps, multiple layers of UV texture coordinates, vertex colors and extended material types.

History, features, overviews, implementation partners and more can be read on the 3MF Consortium’s web site.

Note: Microsoft Windows uses the 3D Manufacturing Format (.3mf) for all 3D printing tasks.
