OpenSCAD is a software for creating solid 3D CAD objects. It is free software and available for Linux/UNIX, MS Windows and MacOS.

BRL-CAD is a powerful cross-platform open source solid modeling system that includes interactive geometry editing, high-performance ray-tracing for rendering and geometric analysis, image and signal-processing tools, a system performance analysis benchmark suite, libraries for robust geometric representation, with more than 20 years of active development.

Browser based 3D solid CAD editor, Openscad style, with a Coffeescript based syntax, using only Coffeescript + Javascript

Creo Elements/Pro – formerly Pro/ENGINEER – is the standard in 3D product design, featuring state-of-the-art productivity tools that promote best practices in design while ensuring compliance with your industry and company standards. Integrated, parametric, 3D CAD/CAM/CAE solutions allow you to design faster than ever, while maximizing innovation and quality to ultimately create exceptional products.

Antimony is a computer-aided design (CAD) tool from a parallel universe in which CAD software evolved from Lisp machines rather than drafting tables.

CadQuery is an intuitive, easy-to-use python based language for building parametric 3D CAD models. CadQuery is for 3D CAD what jQuery is for javascript. Imagine selecting Faces of a 3d object the same way you select DOM objects with JQuery!

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. This provides a number of advantages:

HyperFun is a simple specialized high-level programming language. It is intended for modeling geometric objects and their internal volumetric properties (color, material density and others). A model can include objects of mixed dimensions (1D, 2D, 3D, 4D and even kD)) defined by real functions of point coordinates. This language is applicable to modeling using algebraic, skeleton-based, and procedural “implicit” surfaces, convolution surfaces, distance-based models, voxel objects, constructive solids and volumes, and more general FRep objects.A model in HyperFun is interpreted by the modeling, rendering, animation, and fabrication software tools. »

ScratchyCAD is a web-based parametric 3D design software with a block-based programming language to create objects for 3D printing, animations, games and websites.

BlocksCAD is a 3D CAD program specifically designed to help kids create 3D printable objects while learning math and programming.

CScheme is the integration of geometric kernels in a functional language.

PLaSM (Programming Language of Solid Modeling) is an open source scripting language for solid modeling, a discipline that constitutes the foundation of computer-aided design and CAD systems. In contrast to other CAD programs, PLaSM emphasizes scripting rather than interactive GUI work. Users can create arbitrarily complex designs using a wide range of simple 2D and 3D objects, advanced curves and curved surfaces, Boolean operations, and elementary as well as advanced geometric transformations.

RapCAD is a Rapid prototyping CAD IDE for RepRap and RepStrap 3D printing machines.
