COMPUTER AIDED DESIGN

COMPUTER AIDED DESIGN:-Computer-aided design is the use of computers to aid in the creation, modification, analysis, or optimization of a design. This 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.

Computer-aided design is a way to digitally create 2D drawings and 3D models of real-world products—before they’re ever manufactured. With 3D CAD, you can share, review, simulate, and modify designs easily, opening doors to innovative and differentiated products that get to market fast.

CAD (computer-aided design) is the use of computer-based software to aid in design processes. CAD software is frequently used by different types of engineers and designers. CAD software can be used to create two-dimensional (2-D) drawings or three-dimensional (3-D) models.

Computer aided design or CAD involves using computers to help with engineering and design for a wide range of projects in various industries. It has been important in applied computer science for decades.

Metal fabrication, carpentry, and 3D printing are some common applications for CAD that are valuable in manufacturing.

Another similar type of process to CAD is called computer-aided geometric design (CAGD). In CAGD processes, though, the computer science focuses specifically on creating geometric shapes, which is often used in applications like animation and graphic design, and perhaps less used in 3D manufacturing.

Computer Aided Design is also known as computer-aided design and drafting (CADD).

The purpose of CAD is to optimize and streamline the designer’s workflow, increase productivity, improve the quality and level of detail in the design, improve documentation communications and often contribute toward a manufacturing design database. CAD software outputs come in the form of electronic files, which are then used accordingly for manufacturing processes.

CAD is often used in tandem with digitized manufacturing processes. CAD/CAM (computer-aided design/computer-aided manufacturing) is software used to design products such as electronic circuit boards in computers and other devices.

Application of Computer Aided Design?

CAD is used in a wide variety of professions. CAD software is used heavily within various architecture, arts and engineering projects. CAD use cases are specific to industry and job functions. Professions that use CAD tools include, but are not limited to:

  • Architects
  • Engineers
  • City planners
  • Graphic designers
  • Animation illustrators
  • Drafters
  • Fashion designers
  • Interior designers
  • Exterior designers
  • Game designers
  • Product designers
  • Industrial designers
  • Manufacturers

Modern CAD Tools

As CAD evolved, tools proliferated. Now, in addition to AutoCAD, business users have all sorts of vendor-specific tools to choose from. For example, modern CNC electronic router or woodworking machines have paved the way for more specialization and capability in woodworking shops, from cabinet makers to creators of specialty commercial products. The modern CNC machine’s CNC arm is outfitted with different drills and tools, to be able to plane and otherwise work with wood in a very detailed way. Layers of software, some of which are open source, are used to control the design process and implementation.

Across the board, CAD has been a very valuable part of modern manufacturing and industrial processes.

CAD benefits

Compared to traditional technical sketching and manual drafting, the use of CAD design tools can have significant benefits for engineers and designers:

  • Lower production costs for designs;
  • Quicker project completion due to efficient workflow and design process;
  • Changes can be made independent of other design details, without the need to completely re-do a sketch;
  • Higher quality designs with documentation (such as angles, measurements, presets) built into the file;
  • Clearer designs, better legibility and ease of interpretation by collaborators, as handmade drawings are not as clear or detailed;
  • Use of digital files can make collaborating with colleagues more simple; and
  • Software features can support generative design, solid modeling, and other technical functions.

Computer Aided  Design software/tools
