Computer-aided design Computer-aided design ACIS stands for Alan, Charles, Ian's System. It is a solid modelling geometric modeling kernel that several CAD packages now use. ACIS uses a sophisticated object-oriented approach for modelling, the data is stored in boundary representation. ACIS is owned by Spatial Technology. This was the author's second generation system, the first generation being Romulus. In 1999 around the time when Spatial was bought out by Dassault Systemes, the file format changed slightly and was no longer openly published. ...more on Wikipedia about "ACIS"

Adobe released its last version of Atmosphere, version 1.0 build 216 in February 2004, then discontinued the software in December 2004. The product spent the majority of its lifetime in beta testing. ...more on Wikipedia about "Adobe Atmosphere"
Assembly Modelling is technology and methods used by Computer-aided design and Product visualization computer software systems to handle multiple files that represent components within a product. The components within an assembly are represented as solid or surface models. ...more on Wikipedia about "Assembly modelling"
An associative engine (AE) in CAD/ solid_modelling software is the component which maintains the associative relationships between the collection of geometric entities. The associative relationships are basically LISP expressions which describe the orientation and placement of two or more geometric entities in relationship to each other. AE will force a regeneration through the use of transmigration operations if a user changes any of the associations used to make up the final change_state. ...more on Wikipedia about "Associative engine"
AutoLISP is a programming language, a dialect of Lisp included with the CAD program AutoCAD to allow the user to add functionality to the software. It is not included with the AutoCAD LT product line. ...more on Wikipedia about "AutoLISP"
In computer-aided design, the term boundary representation — often abbreviated as B-REP or BREP, refers to storing information about how to make a model based on its geometric and often Euler topological boundaries. ...more on Wikipedia about "Boundary representation"
CAD data exchange involves a number of software technologies and methods to translate data from one Computer-aided design system to another CAD file format. This PLM technology is required to facilitate collaborative work ( CPD) between OEMs and their suppliers. ...more on Wikipedia about "CAD data exchange"
CAD Standards have been created to improve productivity and interchange of Computer-aided design documents between different offices and CAD programs, especially in architecture and engineering. ...more on Wikipedia about "CAD standards"
CAD/CAM in the footwear industry is the use of computers and graphics software for designing and grading of shoe upper patterns and, for manufacturing of cutting dies, shoe lasts and sole moulds. CAD/ CAM software is a PC-based system, which is made up of program modules. Today, there are 2D and 3D versions of CAD/CAM systems in the shoe industry. ...more on Wikipedia about "CAD/CAM in the footwear industry"
Caddie is a mid-range Computer Assisted Design ( CAD) software package for 2D and 3D design. ...more on Wikipedia about "Caddie (CAD system)"
In CAD or CSG, the change state or delta state (as defined by ACIS) refers to the intermediate modifications made to a document before it is saved. Hence, if one has a history of changes, it is the collective set of intermittent modifications, whose final outcome is one which satisfies certain properties. ...more on Wikipedia about "Change state"
Collaborative Product Development (Collaborative Product Design) (CPD) is a business strategy, work process and collection of software applications that facilitates different organizations to work together on the development of a product. It is also known as collaborative Product Definition Management (cPDM). ...more on Wikipedia about "Collaborative Product Development"
Computer-aided design (CAD) is the use of a wide range of computer-based tools that assist engineers, architects and other design professionals in their design activities. It is the main geometry authoring tool within the Product Lifecycle Management process and involves both software and sometimes special-purpose hardware. Current packages range from 2D vector based drafting systems to 3D parametric surface and solid design modellers. ...more on Wikipedia about "Computer-aided design"
Computer-aided Engineering analysis (often referred to as CAE) is the application of computer software in engineering to analyze the robustness and performance of components and assemblies. It encompasses simulation, validation and optimization of products and manufacturing tools. ...more on Wikipedia about "Computer-aided engineering" If you like you could tell us your opinion about http://www.shortopedia.com shortopedia
Integrating computer-aided manufacturing (CAM) with computer-aided design systems produces quicker and more efficient manufacturing processes. This methodology is applied in different manufacturing areas. ...more on Wikipedia about "Computer-aided manufacturing"
Computervision, Inc. (CV) was an early pioneer in turnkey Computer Aided Design and Manufacturing ( CAD/ CAM). Computervision was founded in 1969 by Marty Allen and Phillippe Villers, and headquartered in Massachusetts, USA. Its early products were built on a Data General Nova platform. Starting around 1975, Computervision built its own, Nova-compatible, computers using its own operating system. In the 1980s, Computervision transitioned to Unix. ...more on Wikipedia about "Computervision"
Digital MockUp or DMU is a 3D virtual technology method for Product visualization; it allows engineers to build large and complex assemblies of components and perform placement, alignment, collision and clearances analysis. It uses tessellation of the geometry to allow real-time moving of components, fly thoughts and 3D dynamic sectioning of products. ...more on Wikipedia about "Digital mockup"
Freeform surface modelling is the art of engineering Freeform Surfaces with a CAD or CAID system. ...more on Wikipedia about "Freeform surface modelling"
Function representation FRep [1] was introduced in [2] as a uniform representation of multidimensional geometric objects (shapes). An object as a point set in multidimensional space is defined by a single continuous real-valued function of point coordinates F(X) which is evaluated at the given point by a procedure traversing a tree structure with primitives in the leaves and operations in the nodes of the tree. The points with F(X) >= 0 belong to the object, and the points with F(X) < 0 are outside of the object. ...more on Wikipedia about "Function representation"
Geometric Work Bench is a BREP file format introducted by Marti Mantyla and discussed in his book "An Introduction to Solid Modeling". This file format is used by several open source CAD CAM modelers as well as MELCAD. ...more on Wikipedia about "Geometric Work Bench"

Many Product Lifecycle Management (PLM) companies have produced engineering software ( CAD/ CAE/ CAM/ PDM) software from the 1970s through to the present. Some of them are listed below. The list is far from complete or representative, since the CAD business landscape is very dynamic: almost every month new companies appear, old companies go out of business, companies split and merge. Sometimes some names disappear and reappear again. ...more on Wikipedia about "List of CAD companies"
