Computer-aided design (CAD) is the use of computer technology to aid in the design of a product, particularly the drafting of a part or the product—a part visual (drawing) and part symbol method of communications particular to a specific technical field.

Hexagon creates these solutions for its clients by leveraging its domain and business expertise long with a complete range of services. With Hexagon, clients are assured of a transparent business partner and world-class processes.

It is in origination, the use of computers to aid the art of drafting—the integral communications of technical drawings — which for a three dimensional object are typically represented by three projected views at right angles —drafting is the Industrial arts sub-discipline which underlies all involved technical endeavors.

CAD is used to design, develop and optimize products , which can be goods used by end consumers or intermediate goods used in other products. CAD is also extensively used in the design of tools and machinery used in the manufacture of components, and in the drafting and design of all types of buildings, from small residential types (houses) to the largest commercial and industrial Structures (hospitals and factories).

CAD is mainly used for detailed engineering of 3D models and/or 2D drawings of physical components, but it is also used throughout the engineering process From conceptual design and layout of products, through strength and dynamic analysis of assemblies to definition of manufacturing methods of components.

CAD has become an especially important technology, within the scope of Computer Aided technologies , with benefits such as lower product development costs and a greatly shortened design cycle.

The HEXACAD is a complete CAD Software with features like 3D Modeling, database connectivity, built in Script support, customized report generation, walk through creation, animation, voice enabled interactive demo creation and many more. This software is compatible with AutoCAD dxf (Drawing Exchange Format) files and up to dwg 2000 file format. Currently hexacad is available on the site with HVAC vertical. Application is developed in VC++ using technologies like OpenGL, ODBC, SAPI, internet, automation etc.
