A geometric modeling kernel is a solid modeling software component used in computer-aided design (CAD) packages. [1] [2] Available modelling kernels include:
The kernel market currently is dominated by Parasolid and ACIS, which were introduced in the late 1980s. The latest kernel to enter the market is KCM. ShapeManager has no presence in the kernel licensing market and in 2001 Autodesk clearly stated they were not going into this business.[ citation needed ]
The world's newest geometric modeling kernel is Russian Geometric Kernel owned by the Russian government, and it is not clear if it is going to be commercially available, despite offering unique features over the other kernels on the market. [20] [21] [22] [23]
In the table below you can see a representative list of developers that belong to companies developing their own kernel or licensing the kernel from third-party. [24]
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.
Solid modeling is a consistent set of principles for mathematical and computer modeling of three-dimensional shapes (solids). Solid modeling is distinguished within the broader related areas of geometric modeling and computer graphics, such as 3D modeling, by its emphasis on physical fidelity. Together, the principles of geometric and solid modeling form the foundation of 3D-computer-aided design, and in general, support the creation, exchange, visualization, animation, interrogation, and annotation of digital models of physical objects.
In solid modeling and computer-aided design, boundary representation is a method for representing a 3D shape by defining the limits of its volume. A solid is represented as a collection of connected surface elements, which define the boundary between interior and exterior points.
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.
Autodesk Revit is a building information modeling software for architects, structural engineers, mechanical, electrical, and plumbing (MEP) engineers, design for contractors. The original software was developed by Charles River Software, founded in 1997, renamed Revit Technology Corporation in 2000, and acquired by Autodesk in 2002. The software allows users to design a building and structure and its components in 3D, annotate the model with 2D drafting elements, and access building information from the building model's database. Revit is 4D building information modeling application capable with tools to plan and track various stages in the building's lifecycle, from concept to construction and later maintenance and/or demolition.
Navisworks is a 3D design review package for Microsoft Windows.
Solid Edge is a 3D CAD, parametric feature and synchronous technology solid modeling software. It runs on Microsoft Windows and provides solid modeling, assembly modelling and 2D orthographic view functionality for mechanical designers. Through third party applications it has links to many other Product Lifecycle Management (PLM) technologies.
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.
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.
Cobalt is a parametric-based computer-aided design (CAD) and 3D modeling program that runs on both Macintosh and Microsoft Windows operating systems. The program combines the direct-modeling way to create and edit objects and the highly structured, history-driven parametric way exemplified by programs like Pro/ENGINEER. A product of Ashlar-Vellum, Cobalt is Wireframe-based and history-driven with associativity and 2D equation-driven parametrics and constraints. It offers surfacing tools, mold design tools, detailing, and engineering features. Cobalt includes a library of 149,000 mechanical parts.
HiCAD is a 2D-/3D-CAD-system from ISD Software und Systeme GmbH based on the software kernel ESM, developed by ISD.
Digital Geometric Kernel, is a software development framework and a set of components for enabling 3D/CAD functionality in Windows applications, developed by DInsight.
