OpenPlant Modeler
What OpenPlant Modeler is
OpenPlant Modeler is parametric 3D plant design software for plant engineers and designers working on projects of any size. It models equipment, specification-driven piping, HVAC, cable trays, and structural steel while keeping project data aligned with 2D drawings and 3D models. Cloud collaboration and PlantSight integration support remote work and digital-twin creation during design. Its ISO 15926 data model and iModel exchange support interoperability with systems such as PDS, SP3D, and PDMS. Designers can reference point clouds and iTwin Capture Modeler reality models, run clash detection, and create customizable material reports. OpenPlant Support Engineering, Bentley Raceway and Cable Management, ProStructures, and OpenPlant Isometrics Manager extend the modeling workflow. The software imports numerous engineering and CAD formats and exports DGN, DWG, DXF, IGES, CGM, STL, SVG, OBJ, and U3D. It runs on 64-bit Windows 10 or 11 and Windows Server 2019 or 2022. Pricing is listed at $5,839 a year, billed annually, with no free plan.
