A short note about AutoCAD !!!

 AutoCAD is the Computer Aided Design (CAD) application both 2D and 3D formats. Typically it bridges the gap between imagination and execution, as designs can be made,

modified , and enhanced in electronic form.

 Characteristics of AutoCAD

 AutoCAD is perhaps the best known leading Computer Aided Design software, widely employed in industry such as aerospace,

Shipbuilding, Construction and Interior, Making the work of drafters, modelers and designers.

 AutoCAD software allows the users to effective conceptualization of ideas, simple modification of engineering designs, and use of varied fonts, colors and textures & other aesthetic features ,rapid design calculations and so on…..

History of AutoCAD

The beginnings of CAD can be traced to year 1957, when Dr. Patrick J. Han ratty developed PRONTO, the first commercial numerical-control programming system. In 1960, Ivan Sutherland MIT’s Lincoln Laboratory created SKETCHPAD, which demonstrated the basic principles and feasibility of computer technical drawing.

In the early 1980s,CAD techniques provided by AutoCAD were accessible only to group of people associated with

Specialize Graphics Terminals. However, the launch or release of the first version of AutoCAD allows the drafters or designing personals to use a tool that could be utilize on standards computers.

2D Time

The first CAD systems served as mere replacements of drawing boards. The design engineer still worked in 2D to create technical drawing consisting from 2D wireframe primitives (line, arc, B spline …). Productivity of design increased, but many argue that only marginally due to overhead – design engineers had to learn how to use computers and CAD. Nevertheless modifications and revisions were easier, and over time CAD software and hardware became cheaper and affordable for mid size companies. CAD programs grew in functionality and user friendliness.

3D Time

3D wireframe features were developed in the beginning of the sixties, and in 1969 MAGI released Syntha Vision, first commercially available solid modeler program.Solid modeling further enhanced the 3D capabilities of CAD systems. NURBS, mathematical representation of freeform surfaces, appeared in 1989 — first on Silicon Graphics workstations. In 1993 CAS Berlin developed an interactive NURBS modeler for PCs, called NöRBS.

Versions of AutoCAD.

The first version of AutoCAD 1.0 got launched back in the year 1982.the application was considered to be the first of its own

Kind and has exclusive features. From that point onwards Autodesk Inc. had launched various updated versions of AutoCAD on

Frequent intervals. Short details of  some of the latest versions and year indicated below.
