AutoCAD is a commercial computer-aided design (CAD) and drafting software application. Developed and marketed by Autodesk, AutoCAD was first released in December 1982 as a desktop app running on microcomputers with internal graphics controllers. Before AutoCAD was introduced, most commercial CAD programs ran on mainframe computers or minicomputers, with each CAD operator (user) working at a separate graphics terminal. AutoCAD is also available as mobile and web apps.
Computer-aided design (CAD) is the use of computers to aid in the creation, modification, analysis, or optimization of a design. This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing. Designs made through CAD software are helpful in protecting products and inventions when used in patent applications. CAD output is often in the form of electronic files for print, machining, or other manufacturing operations. The terms computer-aided drafting (CAD) and computer aided design and drafting (CADD) are also used.
CATIA is a multi-platform software suite for computer-aided design (CAD), computer-aided manufacturing (CAM), computer-aided engineering (CAE), 3D modeling and Product lifecycle management (PLM), developed by the French company Dassault Systèmes.
The 3D ACIS Modeler (ACIS) is a geometric modeling kernel developed by Spatial Corporation, part of Dassault Systemes. ACIS is used by many software developers in industries such as computer-aided design (CAD), computer-aided manufacturing (CAM), computer-aided engineering (CAE), architecture, engineering and construction (AEC), coordinate-measuring machine (CMM), 3D animation, and shipbuilding. ACIS provides software developers and manufacturers the underlying 3D modeling functionality.
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.
SolidWorks is a solid modeling computer-aided design (CAD) and computer-aided engineering (CAE) application published by Dassault Systèmes.
Computervision, Inc. (CV) was an early pioneer in Computer Aided Design and Manufacturing (CAD/CAM). Computervision was founded in 1969 by Marty Allen and Philippe Villers, and headquartered in Bedford, Massachusetts, United States. Its early products were built on a Data General Nova platform. Starting around 1975, Computervision built its own "CGP" Nova-compatible 16-bit computers with added instructions optimized for graphics applications and using its own operating system known as Computervision Graphic Operating System (CGOS). In the 1980s, Computervision rewrote their code to operate on Unix-based platforms.
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.
QCAD is a computer-aided design (CAD) software application for 2D design and drafting. It is available for Linux, Apple macOS, Unix and Microsoft Windows. The QCAD GUI is based on the Qt framework.
EAGLE is a scriptable electronic design automation (EDA) application with schematic capture, printed circuit board (PCB) layout, auto-router and computer-aided manufacturing (CAM) features. EAGLE stands for Easily Applicable Graphical Layout Editor and is developed by CadSoft Computer GmbH. The company was acquired by Autodesk Inc. in 2016.
Parasolid is a geometric modeling kernel originally developed by Shape Data Limited, now owned and developed by Siemens Digital Industries Software. It can be licensed by other companies for use in their 3D computer graphics software products.
Rhinoceros is a commercial 3D computer graphics and computer-aided design (CAD) application software that was developed by Robert McNeil & Friends, an American, privately held, and employee-owned company that was founded in 1969. Rhinoceros geometry is based on the NURBS mathematical model, which focuses on producing mathematically precise representation of curves and freeform surfaces in computer graphics.
The table below provides an overview of notable computer-aided design (CAD) software. It does not judge power, ease of use, or other user-experience aspects. The table does not include software that is still in development. For all-purpose 3D programs, see Comparison of 3D computer graphics software. CAD refers to a specific type of drawing and modelling software application that is used for creating designs and technical drawings. These can be 3D drawings or 2D drawings.
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 longtime 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 Nizhny Novgorod and Novosibirsk, Russia; Bucharest, Romania and Singapore. Bricsys is a founding member of the Open Design Alliance, and joined the BuildingSMART International consortium in December 2016.
FreeCAD is a general-purpose parametric 3D computer-aided design (CAD) modeler and a building information modeling (BIM) software application with finite element method (FEM) support. It is intended for mechanical engineering product design but also expands to a wider range of uses around engineering, such as architecture or electrical engineering. FreeCAD is free and open-source, under the LGPL-2.0-or-later license, and available for Linux, macOS, and Windows operating systems. Users can extend the functionality of the software using the Python programming language.
SolveSpace is a free and open-source 2D/3D constraint-based parametric computer-aided design (CAD) software that supports basic 2D and 3D modeling.
LibreCAD is a computer-aided design (CAD) application for 2D design. It is free and open-source, and available for Linux, macOS, and Windows operating systems.
C3D Toolkit is a geometric modeling kit originally developed by ASCON Group, now by C3D Labs, using C++ and written in Visual Studio. C3D Toolkit responsible for constructing and editing geometric models. It can be licensed by other companies for use in their 3D computer graphics software products. The most widely known software in which C3D Toolkit is typically used are computer aided design (CAD), computer-aided manufacturing (CAM), and computer-aided engineering (CAE) systems.
DesignSpark Mechanical is a free 3D CAD solid modelling software application.
ABViewer is multifunctional software for working with AutoCAD DWG, DXF, PLT, STEP, IGES, STL and other 2D and 3D CAD files. The application allows creating and editing drawings, as well as saving them to AutoCAD DWG/DXF, PDF, JPG and a number of other vector and raster file formats.
