Rig Cad is described as 'Is browser-based parametric CAD for building, configuring, and exporting editable 3D models. It combines several geometry kernels in one readable project tree: solid CSG, NURBS surfaces, meshes, and implicit signed distance fields, so smooth blends and hard boolean' and is an app in the photos & graphics category. There are more than 10 alternatives to Rig Cad for a variety of platforms, including Mac, Windows, Linux, Web-based and Flathub apps. The best Rig Cad alternative is FreeCAD, which is both free and Open Source. Other great apps like Rig Cad are OpenSCAD, Onshape, FluidCAD and Dune 3D.
A powerful open-source parametric 3D modeler ideal for mechanical engineering, supporting Python scripting, running on Windows, Linux, and Mac, with modular architecture allowing extensive adaptability and use with scientific computing libraries.

CadQuery is an intuitive, easy-to-use Python module for building parametric 3D CAD models. Using CadQuery, you can write short, simple scripts that produce high quality CAD models. It is easy to make many different objects using a single script that can be customized.
ImplicitCAD is a programmatic CAD program, implemented in Haskell. Unlike traditional CAD programs, programmatic CAD programs use text descriptions of objects, as in programming. Concepts like variables, control structures and abstraction are used, just as in programming.
