AutoCAD LT:
AutoCAD LT is a "scaled down" version of AutoCAD. It costs less (approx. $900 USD versus around $4,000 USD for the full AutoCAD). It is also available for purchase at computer stores, unlike AutoCAD which has to be purchased from an official Autodesk dealer. It was developed so Autodesk could have an entry-level CAD package available to compete in that price class. Today AutoCAD LT is marketed as a CAD package for those who only need 2D functionality. Compared to the full edition of AutoCAD, AutoCAD LT lacks several features. Most notably, it has no 3D modeling capabilities (though it has a full suite of 3D viewing functions for looking at 3D models created in other CAD packages) and does not include any programming interfaces, such as support for most 3rd party programs and does not support LISP programs. A full listing of differences is on the Autodesk website. AutoCAD LT originated by taking the codebase of AutoCAD and commenting out substantial portions, which allowed AutoCAD and AutoCAD LT to be developed simultaneously.
AutoCAD Student Versions:
AutoCAD is licensed at a significant discount over commercial retail pricing to qualifying students and teachers, with both a 14 month and perpetual license available. The student version of AutoCAD is functionally identical to the full commercial version, with one exception: DWG files created or edited by a student version have an internal bit-flag set (the "educational flag"). When such a DWG file is printed by any version of AutoCAD (commercial or student), the output will include a plot stamp / banner on all four sides.
Vertical programs:
Autodesk has also developed a few vertical programs, sometimes called Desktops, for discipline-specific enhancements. AutoCAD Architecture (formerly Architectural Desktop), for example, permits architectural designers to draw 3D objects such as walls, doors and windows, with more intelligent data associated with them, rather than simple objects such as lines and circles. The data can be programmed to represent specific architectural products sold in the construction industry, or extracted into a data file for pricing, materials estimation, and other values related to the objects represented. Additional tools allow designers to generate standard 2D drawings, such as elevations and sections, from a 3D architectural model. Similarly, Civil Design, Civil Design 3D, and Civil Design Professional allow data-specific objects to be used, allowing standard civil engineering calculations to be made and represented easily. AutoCAD Mechanical, AutoCAD Electrical, AutoCAD Civil 3D, and AutoCAD Map 3D are other examples of industry-specific CAD applications built on the AutoCAD platform.

AUTO CAD
AutoCAD:
AutoCAD is a CAD software application for 2D and 3D design and drafting, developed and sold by Autodesk, Inc. Initially released in late 1982, AutoCAD was one of the first CAD programs to run on personal computers, and notably the IBM PC. Most CAD software at the time ran on graphics terminals connected to mainframe computers or mini-computers.
In earlier releases, AutoCAD used primitive entities — such as lines, polylines, circles, arcs, and text — as the foundation for more complex objects. Since the mid-1990s, AutoCAD has supported custom objects through its C++ API. Modern AutoCAD includes a full set of basic solid modeling and 3D tools, but lacks some of the more advanced capabilities of solid modeling applications.
AutoCAD supports a number of application programming interfaces (APIs) for customization and automation. These include AutoLISP, Visual LISP, VBA, .NET and ObjectARX. ObjectARX is a C++ class library, which was also the base for products extending AutoCAD functionality to specific fields, to create products such as AutoCAD Architecture, AutoCAD Electrical, AutoCAD Civil 3D, or third-party AutoCAD-based applications.
AutoCAD's native file format, DWG, and to a lesser extent, its interchange file format, DXF, have become de facto standards for CAD data interoperability. AutoCAD in recent years has included support for DWF, a format developed and promoted by Autodesk for publishing CAD data. In 2006, Autodesk estimated the number of active DWG files to be in excess of one billion. In the past, Autodesk has estimated the total number of DWG files in existence to be more than three billion.
AutoCAD currently runs exclusively on Microsoft desktop operating systems. Versions for Unix and Macintosh were released in the 1980s and 1990s, but these were later dropped. AutoCAD can run on an emulator or compatibility layer like Virtual PC or Wine, keeping in mind the performance issues that can arise when working with 3D objects or large drawings.
AutoCAD and AutoCAD LT are available for German, French, Italian, Spanish, Japanese, Korean, Chinese Simplified (No LT), Chinese Traditional, Russian, Czech, Polish, Hungarian (No LT), Brazilian Portuguese (No LT), Danish, Dutch, Swedish, Finnish, Norwegian and Vietnamese. The extent of localization varies from full translation of the product to documentation only.

CATIA used for CAD
CATIA:
CATIA (Computer Aided Three dimensional Interactive Application) is a multi-platform CAD/CAM/CAE commercial software suite developed by French company Dassault Systemes and marketed world-wide by IBM. The software was originally intended for the development of Dassault's Mirage fighter jet, but became a runaway success and was subsequently adopted by numerous well known companies world-wide, such as Boeing and IBM. The software was also famously used by architect Frank Gehry in his building of the Guggenheim Museum Bilbao. CATIA is written in the C++ programming language. CATIA is the corner stone of the Dassault Systemes PLM software suite.
Features and capabilities:
Commonly referred to as a 3D Product Lifecycle Management software suite, CATIA supports multiple stages of product development (CAx). The stages range from conceptualization, through design (CAD) and manufacturing (CAM), until analysis (CAE).
CATIA provides an open development architecture through the use of interfaces, which can be used to customize or develop applications. The supporting application programming interfaces are as follows:
*The Fortran and C programming languages for version 4 (V4).
*The Visual Basic and C++ programming languages for version 5 (V5).
These APIs are referred to as CAA for V4 and CAA2 (or CAA V5) for V5. The CAA2 are component object model (COM) like interfaces. They provide integration for products developed on the CATIA suite of software.
Although later versions of CATIA V4 implemented NURBS, version 4 principally used piecewise polynomial surfaces. CATIA V4 uses a non-manifold solid engine.
Catia V5 features a parametric solid/surface-based package which uses NURBS as the core surface representation and has several workbenches that provide KBE support.
As of 2007, the latest release is V5 release 18 (V5R18).
One of the main reasons customers choose CATIA V5 is its ability to seamlessly interact and work in tandem with a host of other applications like Enovia, Smarteam, various CAE Analysis applications etc.
Supported operating systems and platforms:
CATIA V4 is supported for various flavours of Unix - IBM AIX, Hewlett Packard HP-UX, Silicon Graphics IRIX and Sun Microsystems Solaris.Catia V4 and its predecessor versions were also available for IBM MVS and VM/CMS mainframe platforms.
CATIA V5 is provided on Microsoft Windows and the above-mentioned Unixes.

Power Systems CAD
Power Systems CAD:
Power Systems CAD refers to computer-aided design (CAD) software tools that are used to design and simulate complex electrical power systems.
Such power systems are typically found in mission-critical facilities such as computer data centers, network operations centers, air traffic control systems, transportation networks, power plants, manufacturing facilities, etc. The goal of these systems is to ensure that potential electrical power problems are "engineered-out" of the design, prior to a facility being constructed.
Electrical power systems CAD tools are used by electrical power systems engineers, a distinct discipline of electrical engineering. According to the Institute of Electrical and Electronics Engineers (IEEE), there are 21,000 power systems engineers worldwide focused on improving electrical grids, eliminating blackouts, and reducing electrical accidents.Such engineering expertise is instrumental to preserving the critical power needs of modern digital society, e.g. transportation, communications, computing, etc.
In the United States alone, power systems engineering is a $100 billion industry. Power systems CAD tools are credited with dramatically increasing the productivity, efficiency, and effectiveness of electrical systems designers by virtue of their:
Providing a design foundation that allows power systems to be created quickly Enabling design engineers to test the safety and integrity of their design concepts Allowing design engineers to create a repository if proven design elements that can be reused in future projects Thus power systems CAD software products allow organizations to develop higher-quality power systems designs, with faster turnaround time, than ever before possible.
Power Systems CAD Overview:
The electrical power systems CAD process, frequently called power systems "modeling," typically consists of two distinct stages:
The design stage, in which an electric systems model is created, and The simulation or analysis stage, in which software simulation programs are used to test the integrity of the design; these simulation programs test how the model would behave in real-world operation by checking for specific types of design or operational problems.It is important to note that this is an iterative process, in which simulation results will suggest ways that the design should be modified to increase safety, reliability, and serviceability. At the conclusion of the design effort, organizations will enjoy a far higher degree of confidence in the integrity of their power systems infrastructure than with manually-drawn schematics.
Further, in the case of "Power analytics" systems, the CAD model is also used for on-line diagnostics and predictive maintenance, once the facility is constructed.
