MicroStation vs OwlCAD

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.

OwlCAD is a parametric CAD tool for modeling 3D objects and assemblies in a browser or on Windows, macOS, and Linux. Its editor, modeling features, customizer, and file import and export are free forever, and every plan includes commercial rights to sell prints and files. The browser version requires no installation and can be opened without an account. OwlCAD imports and exports STL, 3MF, OBJ, GLB, STEP, SVG, and DXF files, and imports OpenSCAD SCAD and CSG files. Cloud projects autosave and keep version histories that can be rolled back. Projects are private by default; read-only share links, embeds, and comments can be enabled. Print preparation tools check mesh watertightness, repair geometry, estimate filament cost, and split oversized parts, with profiles for Ender 3, Prusa, and Bambu Lab. Published models can expose dimensions, counts, and text as browser sliders for downloadable print-ready versions. Pro adds AI generation and editing, monthly credits, and MCP access for use with Claude Code, Claude Desktop, Cursor, and other MCP clients.
