CAD OVERVIEW WITH ADVANTAGE

In the work place, technology has significantly change the way we go about our every day jobs, in design the introduction of computers and computer software has identified new and exciting ways to go about the design process. Computers have contributed to design for quite a while by providing analysis tools, data-bases and computer-aided drafting tools. Since its introduction 1960s CAD tools have been developed to more user friendly programs we use today.

The last 4 decades has been a back and forward process. It has jumped back and forth between attempts to totally automate the entire design process, to its partial support as a drafting mechanism, from a representation of objects properties, to complete modeling and visualization tool.

Design is an intelligent human process activity which requires many skills and lots of knowledge. Design problems can be solved by individuals or by teams. They may take minutes or years. Design occurs in a wide variety of domains, ranging from the design of a Nuclear Power Plant to that of a simple glass bottle. The general design process is often characterized as mapping needs, functions and structures, this process is carried out by using many different types of analysis and different sources of information. Hand-drawn plans or sketchers can be all a computer aided draftsperson or a modeler needs to get to complete a job. On projects without structural work that don’t require permits, even a quick sketch might be sufficient.

This computing evolution has precipitated a fundamental re-evaluation of space and time. The transition between pre-industrial conditions to a world of computers and cyberspace, taking place in the best part of half a century, affecting the modern designer’s concept of space, which has been an intangible medium for centuries and through constant manipulation and thought, has distinguished the design profession.

CAD TRAINING NOIDA
The value of a computer-aided design (CAD) programs depends entirely on what kind of jobs you do how much design work they regularly involve and the expectations of your client base.

Many consumers can’t envision the result of a 3D modeling project, and therefore have a hard time signing off on a contract. Programs that create realistic two dimensional or three-dimensional images of what the client or designer proposes down to the light at different times of day can help make the sale. Other consumers might not see the charm of a hand-drawn design and consider CAD drawings more professional. CAD programs can definitely accelerate the design process, especially if you do a lot of design work or have clients who change their mind frequently during the design phase. With CAD programs you can change one element of the design, perhaps lengthening one wall of a room, and the proportions of the other walls, the materials list and other affected elements update automatically. Even if your company doesn’t create the design, the ability to share files electronically with suppliers, subcontractors and architects can improve productivity and smooth production.

Advantages of using AUTO CAD TRAINING

• Reduces connectional time for new designs
• Products can be created more quickly.
• Costly mistakes in design or production can be avoided.
• Reduced Manufacturing time.
• Documentation can be printed in various forms for multiple users.
• Ease of document reproduction and cloning
• Visualization of complex technical elements
• The quality of designs.
• Clarity of documentation.
• Easier to apply new ideas.

Disadvantages of using CAD

• Training.
• Expansive start up costs (hardware, software, and training).
• Hard to get the connectional form.

The benefits of 3D CAD design fall into two categories:

Key Benefits:

Using 3D design modeling greatly improves design quality because it is a more complete process than 2D design. As a result, many human errors that can occur with traditional 2D design methods are avoided. In the past problems such as component collisions, incorrect quantities or parts that don't fit, would happen because a designer who works in only 2D is forced to hold much of the information mentally. It is this point that gives rise to errors because the brain CANNOT visualize to exact scale. Reducing human error by using the 3D modeling design methods shown in our 3D CAD manual minimizes the need for re-work because the design quality is greatly improved.

BOM and schedule generation with 2D methods also relies on mental visualization to generate a part count, and thus human error is again a risk when quantifying. With 2D methods, views are visually representative but quantity data from 2D views is poor because projections might show a particular component in several views while other components might be completely omitted to maintain drawing clarity. Using 3D design modeling to get quantity data is easy because items are represented as they occur. Consequently, as long as a CAD 3D design is created as a true to life model, the 3D modeling design represents quantities with exact accuracy. If done correctly - and our 3D CAD manual gives the details how - the CAD 3D modeling method used will give details of blocks and layers (i.e. items) automatically so human error risks when counting quantities become minimal.

Communication of design intent is vastly improved by using CAD 3D modeling. In the past, non technical people interested in a 2D design often had to wait for a prototype before they could truly understand a design. Since cad 3D modeling can be used to generate pictorial views, as well as traditional projections, the design intent can clearly be seen by anyone willing to look. Consequently, it is possible to communicate a 3D modeling design and promote inter departmental understanding earlier in the project cycle, thus creating a time saving. Customer presentations, brochures, manufacturing, and technical publications all benefit. Clearer communication of design intent at the earliest stage is always useful.

The possibilities for concurrent engineering take a real step forward with CAD 3D design because the sheer quality of 3D design modeling data can be instinctively understood and acted on by other departments.

A very impressive and up-to-date approach can be achieved by using 3D CAD modeling - particularly in the eyes of customers. This also applies to individuals because their skills as employees need to be up dated in order to remain competitive in the jobs market.

Advanced Benefits: 

Advanced benefits are more complex, and thus less easy to achieve but at the same time bring great efficiencies in reducing costs and lead times. Put briefly, there will come a time when 3D CAD methods can be smoothly integrated with other computer systems within companies - and even the internet. This will enable users to quickly locate the most cost effective components easily, reducing the CAD operators need to search for, and then model them, as well as allowing production and scheduling software to have visibility of bills of material that are evolving as the 3D CAD modeling develops. Although difficult to achieve at present, this will become common place in time, but only for those who work in 3D CAD methods.

2D methods are not able to relay the quality and quantity of design information because 2D methods will always rely on human interpretation or visualization skills to interact with a 2D design. Interpretation, visualization and interaction with a 2D design is always difficult for non design staff and almost impossible for computer systems to extract information, because computers do not have the ability to interpret representative (I.e. incomplete) visual information.
