MicroStation

MicroStation is Bentley Systems' 3D CAD and modelling application, built for the design, documentation and visualisation of infrastructure projects across architecture, engineering and construction. It is a general-purpose modelling environment that handles projects of essentially any size and complexity, from a single building to a bridge, highway, rail corridor, plant or utility network. The software supports both 2D drafting and full 3D parametric modelling within the same file, along with mesh, solid and surface geometry, so engineers can move between conceptual massing, detailed design and construction documentation without leaving the application. Its reputation rests substantially on stability at scale: MicroStation handles very large datasets, reality meshes, point clouds and federated models that would overwhelm lighter tools, and it maintains precision across the enormous coordinate ranges that civil and infrastructure work demands. Native DGN format is complemented by strong DWG interoperability, plus support for IFC and a wide range of other industry exchange formats.

Beyond geometry, MicroStation provides drawing production, annotation, sheet composition and printing tools geared to the deliverable standards of engineering practice, along with built-in visualisation covering rendering, animation and walkthroughs for design review and stakeholder communication. It functions as the technical foundation for much of Bentley's wider portfolio, meaning organisations already using Bentley's discipline-specific applications gain a consistent modelling core and shared data environment across teams. Scripting and customisation are extensive, allowing large firms to encode their own standards, automate repetitive drafting and integrate the tool into established workflows. Collaboration and version management connect to Bentley's cloud services for distributed project teams. The target user is the professional infrastructure practice rather than the occasional modeller — civil engineers, structural engineers, plant designers, surveyors and architects working on large or long-lived assets where data longevity, accuracy and interoperability matter more than ease of casual use. Pricing reflects that positioning, starting from roughly USD 2,284, and a free trial is available for evaluation. There is no free version. Expect a substantial learning investment; in return, the software is rarely the limiting factor on project scale.
