What OpenPlant Modeler is

OpenPlant Modeler is parametric 3D plant design software for Windows, built for plant engineers and designers. It supports 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. The software uses ISO 15926 as its data model and exchanges information through iModels, including references from PDS, SP3D, and PDMS. Designers can work with point clouds and reality models, run clash detection, and generate customizable material reports. It imports engineering and CAD formats such as IGES, Parasolid, STEP, STL, and CAD files, and exports DGN, DWG, DXF, IGES, CGM, STL, SVG, OBJ, and U3D. Supported systems include 64-bit Windows 10 or 11 and Windows Server 2019 or 2022. The listed plan is $5,839 a year, billed as a 12-month Virtuoso subscription with one license and two training or service keys.
