FluidCAD is a parametric CAD tool that uses JavaScript for scripting, enabling developers and engineers to create 3D models programmatically. It provides a familiar CAD workflow—sketches, extrusions, fillets, shells, booleans—but expressed in code. Users write JavaScript functions to define geometry, and the 3D scene updates in real time. The tool includes smart defaults (e.g., extrude picks up the last sketch), shape references (faces, edges, vertices), and feature transforms like linear and circular patterns. It supports STEP import/export for interoperability with standard CAD tools.
