OwlCAD vs Rhino 3D

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.

Rhino 3D is desktop software for Windows and macOS with listed capabilities for parametric modeling, animation, rendering, and 3D print export. The commercial Rhino 8 single concurrent-user license is listed at $995 a month, billed as a permanent license that does not expire. Licenses for 10 and 50 concurrent users are listed at $9,950 a month and $49,750 a month, respectively, also as permanent licenses. Student or faculty and school options are listed, with educational-status or school-licensing requirements. Commercial and student or faculty upgrade options are available, though evaluation versions cannot be upgraded. A free evaluation license costs nothing and lasts 90 days; saving and plugins stop working after that period. The listing describes Rhino 3D as paid while also indicating a free plan and free trial. Its maker is listed as founded in 1980 and based in Seattle, Washington, USA.
