AutoCAD is software for doing 2D and 3D computer aided designs. Auto CAD is used for drafting and designing. Auto CAD allows a user to develop ideas, make  product designs, visualize drawings to the required technical accuracy, as well as perform rapid design calculations and simulations in the construction industry. AutoCAD is mostly used by architectures, engineers, interior designers, real estate developers and artists. It reduces human errors as well as helps users bring their imagination to life with precision.

It is easy to edit

Before the age of computers, a designer had to manually modify designs.  You will need to create a new draft or edit the draft you have, which can be confusing and difficult to interpret.  With AutoCAD, you can easily change and manage designs.

Faster in Production

You can create a reusable block library to repeat design parts.  Got a working window system?  Use it again.  A construction component you need again and again?  To maximize efficiency, save it to your block library.  Saved files can be reused and reused later, which speeds up the design process faster than when you do it by hand.

Provides Better Accuracy

You can only draw something very small by hand, but AutoCAD allows you to design into fractions.  This creates a more precise design in all dimensions.

AutoCAD is derived from Interact written it is a program that in the proprietary language.  The first version of this software used only by the primitive institutions of polygons, circles, arcs, lines, and text to create complex objects.  It came to support custom objects through the C ++ application programming interface in later.  The modern version of the software includes a set of tools for solid modelling, and 3-D. AutoCAD supports several application programs such as interfaces for automation and customization.

DWG (Drawing) is the native file format for AutoCAD and the basic standard for CAD data interoperability.  The software supports the Design Web Format (DWF) developed by Autodesk for publishing CAD data.

Autodesk offers free trials of AutoCAD, among many other programs in the design suite. Users can also take full advantage of AutoCAD’s full range of features for free trial. However, this means that for non-educational users, the time limit for free use of AutoCAD is limited.  The student version of AutoCAD will free for 3 years.
