AVEVA E3D Design vs OwlCAD

AVEVA E3D Design is a data-centric, multidiscipline 3D engineering design tool within AVEVA Unified Engineering. It uses parametric modelling with assembly design and surface modelling, and supports Windows 10, Windows 11, Windows Server 2019, Windows Server 2022 and browser access. Teams can collaborate through cloud data services, working on shared project data with near-real-time coordination. The software identifies clashes across disciplines and generates drawings and deliverables that update with the design. It imports and exports DXF, DWG, IFC 2x3, IFC4, DGN, STL and STEP files. Built-in capabilities include an industrial assistant, predictive and generative design tools, laser-scan data handling and integrations with engineering and asset systems. Custom functionality can use macros, PML and a .NET API. Listed data features include real-time stream processing, custom dashboards, anomaly detection and machine-learning tools. AVEVA describes Flex subscription licensing across cloud, hybrid and on-premises deployments; pricing is available on request.

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.
