A 2D CAD drawing A 3D CAD model Computer-aided design ( CAD ) is the use of computers (or workstations ) to aid in the creation, modification, analysis, or optimization of a design . [ 1 ] : 3 This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to ...
In 3D computer graphics, 3D modeling is the process of developing a mathematical coordinate-based representation of a surface of an object (inanimate or living) in three dimensions via specialized software by manipulating edges, vertices, and polygons in a simulated 3D space.
3D rendering of a car in CAD software with boundary representation. Also important to the development of CAD was the development in the late 1980s and early 1990s of B-rep solid modeling kernels (engines for manipulating geometrically and topologically consistent 3D objects), Parasolid (ShapeData), and ACIS (Spatial Technology Inc.). These ...
A geometric modeling kernel is a solid modeling software component used in computer-aided design (CAD) packages. [1] [2] Available modelling kernels include: ACIS is developed and licensed by Spatial Corporation of Dassault Systèmes. SMLib is developed by Solid Modeling Solutions. [3] Convergence Geometric Modeler [4] is developed by Dassault ...
Solid modeling (or solid modelling) is a consistent set of principles for mathematical and computer modeling of three-dimensional shapes . 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. [ 1 ]
Digital modeling and fabrication is a design and production process that combines 3D modeling or computing-aided design (CAD) with additive and subtractive manufacturing. Additive manufacturing is also known as 3D printing , while subtractive manufacturing may also be referred to as machining , [ 1 ] and many other technologies can be exploited ...
