AutoCAD is a 2D and 3D computer-aided design (CAD) software application developed by Autodesk. It was first released in December 1982 for the CP/M and IBM PC platforms as a desktop app running on microcomputers with internal graphics controllers. Initially a DOS application, subsequent versions were later released for other platforms including Classic Mac OS (1992), Microsoft Windows (1993) and macOS (2010), iOS (2010), and Android (2011).
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 help protect 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.
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.
CAD data exchange is a method of drawing data exchange used to translate between different computer-aided design (CAD) authoring systems or between CAD and other downstream CAx systems.
Rhinoceros is a commercial 3D computer graphics and computer-aided design (CAD) application software that was developed by TLM, Inc, dba Robert McNeel & Associates, an American, privately held, and employee-owned company that was founded in 1978. Rhinoceros geometry is based on the NURBS mathematical model, which focuses on producing mathematically precise representation of curves and freeform surfaces in computer graphics.
ArchiCAD is an architectural BIM CAD software for Mac and Windows developed by the Hungarian company Graphisoft. ArchiCAD offers computer aided solutions for common aspects of aesthetics and engineering during the design process of the built environment-buildings, interiors, urban areas, etc.
Open Design Alliance is a nonprofit organization creating software development kits (SDKs) for engineering applications. ODA offers interoperability tools for CAD, BIM, and Mechanical industries including .dwg, .dxf, .dgn, Autodesk Revit, Autodesk Navisworks, and .ifc files and additional tools for visualization, web development, 3D PDF publishing and modeling.
Spatial Corporation was founded in 1986, and had one main product: ACIS, the first commercially available 3D modeling kernel. Through subsequent years, Spatial added products to its portfolio that enabled ISVs mostly in the CAD/CAM industries, to build applications. These components included extensions and updates to the ACIS modeler, visualization products, as well as acquisitions in translator technology.
PRC is a file format that can be used to embed 3D data in a PDF file.
T-FLEX CAD (T-FLEX) – is a parametric computer-aided design (CAD) software application for 2D design, drafting, and 3D solid modeling based on commercial Parasolid geometric kernel. It's primarily developed and distributed by Russian software company Top Systems. Supported platforms are limited to Microsoft Windows. Amongst features T-FLEX offers support for various CAD formats and diverse localizations.
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.
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.
HOOPS Visualize is a 3D computer graphics software designed to render graphics across both mobile and desktop platforms. HOOPS Visualize provides 3D Graphics API to render CAD models. It's part of the HOOPS 3D Application Framework SDK. Since June 2018 it's licensed via Siemens PLM Software.
Autodesk Inventor is a computer-aided design extension application for 3D mechanical design, simulation, visualization, and documentation developed by Autodesk.
