What is Computer-aided design (CAD) and its advantages or disadvantages
Computer-aided design (CAD), also known as computer-aided design and drafting (CADD), is the use of computer technology for the process of design and design-documentation. Computer Aided Drafting describes the process of drafting with a computer. for the processes; drafting, CADD software, or environments, provides the user with input-tools of purpose design streamlining documentation, and manufacturing processes.
What is Computer-aided design (CAD)?
1. CADD software also helps to create wireframe models. One can create models and also see the success of it by working on simulations being provided with the software.
2. Current computer-aided design software packages range from 2D vector-based drafting systems to 3D solid and surface modellers.
3. Modern CAD packages can also frequently allow rotations in three dimensions, allowing viewing of a designed object from any desired angle, even from the inside looking out.
4. Output is often in the form of electronic files for print or machining operations. CADD environments often involve more than just shapes.
5. As in the manual drafting of technical and engineering drawings, the output of CAD must convey must convey information, such as materials, processes, dimensions, and tolerances, according to application-specific conventions.
6. CAD may be used to design curves and figures in two-dimensional (2D) space; or curves, surfaces, and solids in three-dimensional (3D) objects. CAD is an important industrial art extensively used in many applications, including
(i) Automotive
(ii) Ship building
(iii) Aerospace industries
(iv) Industrial and architectural design Prosthetics 0 A 40
(vi) Computer animation for special effects in movies
(vii) Advertising and technical manuals. I-1.5 CAD has been a major driving force for research in computational geometry, computer graphics (both hardware and software), and discrete differential geometry.
Advantages of computer aided design
i) With the help of modern CAD software, project managers can produce better and efficient designs with less time and high degree of accuracy.
(ii) CAD drafting services focus on converting hand-drawn sketches and blueprints into a complete editable digital design. This allows easy customization and revision of design to suit the requirements of architects, interior designers or structural engineers.
(iii) CAD can give you multiple drawings in the same time-frame as compared to manual drafting.
(iv) Designer can better visualize the design using 3D modeling which in turn helps increase accuracy and minimize errors.
(v) With CAD services you have your design concepts and drawings digitally stored on a common database. Each team member can have access to every detail of the project right from design to installation.
(vi) Digitization and 3D modeling helps you make easy and quick revisions which in turn reduce errors before construction or fabrication starts. What you gain here is a competitive advantage.
Disadvantages of computer aided design
(i) Installations of the software is very costly.
(ii) Training involved for teaching the software is very expensive.
(iii) It is difficult to keep track of changes when many people are working on drawings for a project
(iv) Traditional skills will no longer be required and people will lose their jobs.
