Computer Aided Design

• Computer-aided design (CAD) is the use of computer systems to assist in the creation, modification, analysis, or optimization of a design. CAD software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing. CAD output is often in the form of electronic files for print, machining, or other manufacturing operations.

• Computer-aided design is used in many fields. Its use in designing electronic systems is known as Electronic Design Automation, or EDA. In mechanical design it is known as Mechanical Design Automation (MDA) or computer-aided drafting (CAD), which includes the process of creating a technical drawing with the use of computer software.

• 3D CAD drawing

Examples of CAD drawing

• (1) Autocad:AutoCAD is a software application for 2D and 3D computer-aided design (CAD) and drafting — available since 1982 as a desktop application and since 2010 as a mobile web- and cloud-based app, currently marketed as AutoCAD 360.• Developed and marketed by Autodesk, Inc.,AutoCAD was

first released in December 1982 — having been purchased a year prior in its original form by Autodesk founder John Walker. The software is currently marketed in its eighteenth generation

• (2) Autocad LT• The lower cost version of AutoCAD.• What are the differences between AutoCAD 2014

and AutoCAD LT 2014?Autodesk® AutoCAD® 2014 software differs from AutoCAD LT 2014 in three primary ways:• · 3D Modeling: AutoCAD LT does not contain any

tools for 3D modeling or conceptual design.

• · Customization: The functionality of AutoCAD LT cannot be extended or customized with the use of

• programming languages like LISP, VBA, and .NET that AutoCAD supports. This includes Express Tools,

• which are available for AutoCAD only.• · Network Licensing: AutoCAD can be run via a

network license. This option is not available for AutoCAD LT.

(3) SolidEdge a 3D CAD parametric feature solid modeling software. It provides solid modeling, assembly modelling and drafting functionality for mechanical engineers, designers and drafters

(4) Autodesk Inventor3D mechanical CAD design software for creating 3D digital prototypes used in the design, visualization and simulation of products.

(5) Autocad 360With the AutoCAD® 360 web and mobile app, you can view, create, edit, and share CAD drawings nearly anytime, anywhere. Get essential tools for sketching and documenting. This free* CAD for mobile app enables you to redline drawings on-site, document as-builts, and share DWG drawings. Formerly known as AutoCAD WS.
