Engineering on Web - Free browser CAD, FEA and statistics
Engineering on Web is a free suite of three engineering tools that run entirely in the web browser, with nothing to install and no account required.
The CAD module handles parametric 3D modeling with constrained sketches, assemblies and technical drawings, and exports STL, STEP, IGES and DXF. Its AI assistant creates features from a typed or spoken description and can vectorize a photographed sketch.
The FEA module solves structural, thermal, fluid and electromagnetic problems in 2D and 3D with WebAssembly solvers and WebGPU acceleration. The Analysis module covers control charts, process capability and design of experiments, with AI that explains the results in plain language.
Available in ten languages, it is made for engineering students, teachers and small workshops that need CAD, simulation and quality statistics without commercial licenses.
