InterBridge performs on-line translations of 2D and 3D models and data between a variety of CAD, BIM, and PLM systems. Our service is designed to assist you in sharing 2D and 3D models as you develop and view large-scale processing facilities. InterBridge manages facilities information to carry them through their life cycle. InterBridge is the essential tool for working successfully in heterogeneous CAD/BIM/PLM environments.

InterBridges System Requirements

    InterBridge requires no installation or administration. The product has minimal hardware requirements, and so visualizes 3D models of large processing facilities on ordinary office PCs. The minimum requirements are listed below:

  • 32- and 64-bit OS: Microsoft® Windows 8 and 7, Microsoft Vista, Microsoft XP and 2000
  • Processor: Intel Pentium/Celeron (or compatible), 450MHz or higher
  • Graphics board: OpenGL 1.1 or higher
  • Memory: 128MB
  • Disk space: 4MB install size

Comparing with Analogous Software

InterBridge boasts excellent performances in benchmarks of large-scale projects typical of those found in the oil, gas, chemical, and defense industries. Our benchmarking reported the following results:

  • Most compact software: The InterBridge distribution package is only 2MB, hundreds times smaller than competitors; see figure below.
  • The most productive software: InterBridge is able to manipulate very large 3D models (made of several hundred thousand elements) requiring a significantly smaller amount of memory; see figure below.

  • Fastest operations: InterBridge opens 3D models of large facilities (consisting of several hundred thousand elements) quickly, literally “flying” even on standard office computers. The software instantly opens the model, and then makes is ready for operators to manipulate the model in any way. Other software systems are sometimes unable to handle giant models, or simply cannot open models of this type. See figures below.

    The results come from a comparative analysis carried out by NEOLANT staff using the following hardware and software configuration:

  • Hardware: 3.4GHz Intel Core i7-4770 with 8GB RAM and NVIDIA GeForce GT640 4GB graphics board running on 64-bit Windows 7
  • Software: InterBridge 2015.2 2015.828, compared to Autodesk Navisworks Manage 2016 (64x) 13.0.1240.5, Bentley Navigator V8i (SELECTseries 6), and Intergraph SmartPlant Review 2015R1 (
  • 3D Model: 842MB with 131,016 elements
