Free, browser-based 3D CAD modeling with parametric scripting and solid geometry.
Product memo
NASSCAD delivers a precise, independent 3D CAD experience directly in the browser. It avoids cloud requirements and installations, operating from a single HTML file for offline use. Its parametric scripting and non-destructive CSG engine handle complex mechanical designs, exporting directly to slicer-ready formats like STL, OBJ, and 3MF. The CC BY-NC 4.0 license emphasizes user ownership and removes subscription or telemetry friction.

About NASSCAD 4.2.30 Expand
NASSCAD provides a browser-based 3D CAD modeling experience for designers and engineers. It focuses on precision and independence, operating as a single HTML file without requiring cloud connections or installations.
Users use parametric scripting and a non-destructive CSG engine to build complex mechanical designs. The tool supports direct export to common 3D printing formats like STL, OBJ, and 3MF.
Its CC BY-NC 4.0 license underscores a commitment to user ownership, removing typical subscription costs and data telemetry concerns associated with other CAD software.
