Our verdict on OpenPlant Modeler
OpenPlant Modeler is Windows-based 3D CAD software for engineering firms, owner-operators, and project teams designing process, mining, water, wastewater, and power facilities. Its parametric approach covers equipment, specification-driven piping, HVAC, cable trays, structural steel, and equipment placement. The product also supports multidisciplinary plant design, clash detection, customizable material reporting, and import and export across engineering and CAD formats. It is designed for teams that need plant-specific modeling rather than a general-purpose 3D design workflow.
The published plan is OpenPlant Modeler at $5,839 per license per 12 months, billed annually. The plan highlights collaborative 3D plant design, parametric equipment modeling, and PlantSight digital twin workflows. The subscription includes one license plus two service or training Keys, and pricing varies by region. This makes the licensing structure straightforward, while the annual per-license cost is a significant consideration for teams comparing specialized plant design software.
Its strongest fit is an engineering environment already aligned with Bentley workflows. Integrations include PlantSight, iTwin, ProjectWise, OpenPlant Isometrics Manager, Bentley Raceway and Cable Management, and ProStructures. Collaboration can extend through PlantSight and iTwin workflows, while point-cloud and reality-model integration supports projects that combine modeled and captured site information. Windows 11 or 10 and Windows Server 2019 or 2022 are supported, and the format list includes DGN, DWG, DXF, IGES, CGM, STL, SVG, OBJ, U3D, Parasolid, ACIS SAT, STEP, Terrain Model Land XML, and other CAD files. Choose it for specification-driven plant projects and Bentley-centered collaboration; consider a broader CAD product for work outside plant engineering.
