Cascade Studio

Download from the vendor
zalo.github.io
A browser-based CAD environment where you write the model as JavaScript code (or OpenSCAD syntax) and it is built instantly in a 3D view. The library offers primitives, boolean operations, sweeps, lofts and fillets, sketches, face and edge selection, and volume, surface area and centre-of-mass measurement. You can import STEP, IGES and STL, export STEP, STL and OBJ, and share a model through its link. Suited to mechanical engineers who want parametric parts reproducible from code. Limitation: there is no graphical sketching interface; everything is built in code.
