1. Computer Aided Design

2. 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 designform of electronic files

3. 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.Electronic Design Automation Mechanical Design Automationtechnical drawing

5. 3D CAD drawing

6. 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.software application2D3D computer-aided design (CAD)draftingapp 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 generationAutodesk, Inc.John Walker

7. (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.

8. · 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.

9. (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

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

11. (5) Autocad 360 With 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.
