OpenSCAD is a free software application for creating solid 3D computer-aided design (CAD) objects. It is a script-only based modeller that uses its own description language; the 3D preview can be manipulated interactively, but cannot be interactively modified in 3D. Instead, an OpenSCAD script specifies geometric primitives (such as spheres, boxes, cylinders, etc.) and defines how they are modified and combined (for instance by intersection, difference, envelope combination, or Minkowski sums) to render a 3D model. As such, the program performs constructive solid geometry (CSG). OpenSCAD is av

LibreCAD is a computer-aided design (CAD) application for 2D design. It is free and open-source, and available for Unix/Linux, macOS, and Microsoft Windows operating systems.

BRL-CAD is a constructive solid geometry (CSG) solid modeling computer-aided design (CAD) system. It includes an interactive geometry editor, ray tracing support for graphics rendering and geometric analysis, computer network distributed framebuffer support, scripting, image-processing and signal-processing tools. The entire package is distributed in source code and binary form.

BricsCAD is a software application for computer-aided design (CAD), developed by Bricsys NV. The company was founded in 2002 by Erik de Keyser, a long-time CAD entrepreneur. In 2011 Bricsys acquired the intellectual property rights from Ledas for constraints-based parametric design tools, permitting the development of applications in the areas of direct modeling and assembly design. Bricsys is headquartered in Ghent, Belgium, and has additional development centers in Bucharest, Romania and Singapore. Bricsys is a founding member of the Open Design Alliance, and joined the BuildingSMART Interna

VariCAD is a computer program for 3D/2D CAD and mechanical engineering which has been developed since 1988 in the Czech Republic. VariCAD runs on Windows and Linux. It features many tools for 3D modeling and 2D drafting. VariCAD provides support for parameters and geometric constraints, tools for shells, pipelines, sheet metal unbending and crash tests, assembly support, mechanical part and symbol libraries, calculations, bills of materials, and more.

MeshLab is a 3D mesh processing software system that is oriented to the management and processing of unstructured large meshes and provides a set of tools for editing, cleaning, healing, inspecting, rendering, and converting these kinds of meshes. MeshLab is free and open-source software, subject to the requirements of the GNU General Public License (GPL), version 2 or later, and is used as both a complete package and a library powering other software. It is well known in the more technical fields of 3D development and data handling.

Sunflow is an open-source global illumination rendering system written in Java. The project is currently inactive; the last announcement on the program's official page was made in 2007.

rattleCAD is a parametric 2D computer-aided design (CAD) software specific for bicycle design, in particular for design bicycle frame, developed by the Austrian cyclist and programmer Manfred Rosenberger since 2008. The application is written in the programming language Tcl using the Tk-based graphical user interface (GUI).
