How to convert Intergraph PDS to glTF?

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.

glTF

As described more extensively on Okino's dedicated glTF converter page, glTF is a newer 3D file format designed for the "last mile" of efficient, real-time delivery of 3D assets for Web-based browsers, AR/VR applications and gaming applications, amongst others. It is generally not to be considered as a long term and high fidelity 3D data storage format (such as FBX, COLLADA or VRML2) but rather an efficient transmission and viewing 3D file format. It has begun to gain good traction in recent years.

glTF stands for Graphics Language Transmission Format. glTF is intended as a vendor-neutral distribution format for 3D content, bridging the gap between 3D content creation tools and applications displaying 3D graphics. It is fully graphics API and operating system-independent.

Okino has one of the most extensively developed and refined implementations of glTF for both import and export.
