OpenBuildings Designer CONNECT Edition

Interoperable and Scalable Buildings Design (BIM) software

WHAT is OpenBuildigs Designer CONNECT Edition?

OpenBuidlings Designer CONNECT Edition is the successor to Bentley’s AECOsim Building Designer, it includes MicroStation Triforma, Speedikon, Bentley Architecture, Bentley Structural, Bentley Building Mechanical Systems, Bentley Building Electrical Systems, Hevacomp Mechanical Designer, and Hevacomp Simulator.

OpenBuidlings Designer CONNECT Edition can do Design (Native DGN or DWG format), Analyze (Building Energy simulation), Documentation (Construction drawing), Visualization (With LumenRT Plugin), and Computation Design (GenerativesComponent).

OpenBuidlings Designer CONNECT Edition is designed for Interoperable and Scalable Buildings Design (BIM) software.


Highlight Features:

  1. Multidiscipline - Includes tools for architectural, electrical, mechanical, and structural systems design. Design-as-a-Mode workflow.
  2. Design - Native parametric modeling with Real DWG and Native DGN. Also, integrate with ProStrucutres to produce detailing drawings.
  3. Documentation - Link specifications, engineering calculations, and equipment documentation to models and drawings.
  4. Dynamic Modeling - Refine design alternatives to explore more possibilities in less time or "what-if" scenario modeling.
  5. Visualize - Generate images and animation with life-like and high-end photo-realistic renderings itself or LumenRT
  6. Analyze - Simulate real-world performance and evaluate building system performances.



    OpenBuildings GenerativeComponents Extension

    A Computation modeling design tool using for complex parametric modeling. (Included in package)


    On-demand Video : GenerativeComponents 


      AccuDraw - a smart drafting aid tool that helps to create parameters.  (Included in package)



       MicroStation CONNECT Edition is included as a mode in OpenBuildings Designer CONNECT Edition.


       OpenBuildings Designer can collaborate with other design tools via ISM (Integrated Structural Modeling)
