Autodesk Inventor vs MicroStation

Autodesk Inventor is Windows software for mechanical design, documentation, simulation, and model-based definition. Its 3D tools combine parametric, direct, freeform, and rules-based modeling, with support for assembly design, sheet metal, and surfaces. Inventor can open designs from other CAD systems without translation. Parts can be exported to formats including DWG, IGES, JT, OBJ, STEP, and STL; assembly exports also include RVT, while drawings support DWG, IDW, DWF/DWFx, and DXF. Design connections include Revit family data, Vault, Factory Design Utilities, and Inventor Nastran. Automation options include iLogic, the API, and Autodesk Platform Services. Inventor is paid, with a 30-day trial and no permanent free tier. Displayed monthly, annual, and three-year prices are placeholders, not figures. A subscription permits installation on up to three devices, but only the named user may sign in and use it on one computer at a time.

MicroStation is paid Windows desktop CAD software for precise 2D drawings and 3D infrastructure models. It targets engineers, architects, and construction professionals, combining CAD with built-in BIM capabilities. Workflows include parametric constraints, reusable cells, and automatic documentation from models. BIM-ready models integrate with OpenBuildings Designer, OpenRoads, OpenRail, and ProjectWise. Geospatial work can combine vector and raster data, Esri ArcGIS REST services, Google Maps, imagery, point clouds, and reality meshes. MicroStation imports DWG, DXF, and IFC into DGN files, references DWG files, and converts DGN files to iModels. A Python API supports scripting, while Python Assistant and Bentley Copilot are listed as technology previews. The product supports Windows 11 and Windows Server 2022 or 2025, and offline use is listed. There is no free plan; a trial requires a request, eligibility review, and approval.
