FEATURE OF AUTOCAD

FAutoCAD is an interactive drawing system designed to permit a user to construct or edit a drawing on a graphics display screen. It was introduced in the early 1980’s by “Autodesk Inc.”, California, and U.S.A. 

FEATURE OF AUTOCAD Training 

Following are some of the distinguish features on the basis of which we prefer working in AutoCAD   instead of working manually. 

You can create fine drawings with hundreds of colors, line types, hatch patterns, presentation symbols and text styles. Even if you don’t like something about your presentation after you have finished it, you can quickly change it. It takes only a few simple steps to change the text style, color or line type and you can print a fresh copy of the drawing.

There are a number of ready-made presentation symbols and hatch patterns available in CADD that can be used to enhance the look of drawings. For example, a site planner can add tree symbols, shrubs, pathways, human figures, and other landscape elements to create a site plan. Similarly, an architect can use ready-made symbols of doors, windows, furniture, etc., to make a presentation.

In addition to preparing impressive presentations on paper, you can use CAD to make on- screen presentations. You can plug your computer into a projector and present your ideas on-   screen. Advanced CAD programs even allow you to create animated images. You can   illustrate how a building would appear while walking through it, or how a machine would function when different machine assembly parts operate.

CAD provides the flexibility to make quick alterations to drawings. You can erase any portion 

Of a drawing with pinpoint accuracy. It takes only seconds to do a job that could take hours on a drawing board. In many cases, you won’t even have to erase the drawing to make the change.  You can rearrange the existing components of the drawing to fit new shape. This enables you to analyze design options with minimal effort.

The following are some of the editing capabilities of CAD:

      · Move or copy drawing elements

      · Enlarge or reduce parts of a drawing

      · Add one drawing to another

      · Stretch a drawing to fit new dimensions

      · Make multiple copies of a drawing element

      · Change the size and style of text

      · Change units of measure, accuracy and style of dimensions

REASON FOR AUTOCAD Training

The most potent driving force is competition. In order to win business, companies used CAD to produce better designs more quickly and more cheaply than their competitors. 

Productivity is much improved by a CAD program enabling you to easily draw polygons, ellipses, multiple parallel lines and multiple parallel curves.

The speed is increased by the use of automatic fillets and chamfers; 

the computer ability to "snap" automatically to particular geometric points and features will spread the accurate positioning of line work. 

Copy, rotate and mirror facilities are also very handy when drawing symmetrical parts.

CAD is very suitable for repetitive and fast documentation where a product is one in a range of sizes. Assume that you manufacture a range of motor driven pumps operating at different pressures. Many parts will be used in different combinations in the range and the computer database documentation is programmed accordingly. 

A computerized tender can be sent with the appropriate specification and technical details. On receipt of an order, all of the documentation relating to manufacture, testing, dispatching and invoicing will be available.

Many CAD systems permit the rapid generation of models of proposed designs as wire-frames. The computer memory stores details of all the geometric data to define each part of the frame. From the dimensions of the components, the computer will calculate surface areas, volumes, weights for different materials, center of gravity, moments of inertia and radii of gyration; it can also use the applicable value for stress and other calculations, which are necessary part of design.

The biggest contribution of computers to the design process is soft prototyping - the process of creating a 3D-computer model of a design that can be subjected to computer-based testing. Soft prototypes are almost faster and cheaper to built than real prototypes and are often better at their main activity than a real ones; That because model shop prototypes usually use processes and materials very different from those ultimately used for the production version of the product.

A typical design involves producing part drawings in a CAD program right up to completion of design and making layers of the geometry required for the CAM processing software. The description of part created in a CAD program is translated into an appropriate format, such as DXF or IGES, and then loaded into the CAM programs which are used then to create tool paths that trace this description. This path can be edited and combined with other tool path files where necessary and the combined forms a complete program for the machine tool to manufacture the part.
