What is the technique
Computer Aided Design-CAD is defined the use of information technology (IT) in the
Design process. A CAD system consists of IT hardware (H/W), specialised software
(S/W) (depending on the particular area of application) and peripherals, which in certain applications are quite specialised. The core of a CAD system is the S/W, which makes use of graphics for product representation; databases for storing the product model and drives the peripherals for product presentation. Its use does not change the nature of the design process but as the name states it aids the product designer. The designer is the main actor in the process, in all phases from problem identification to the implementation phase. The role of the CAD is in aiding him/her by providing: n Accurately generated and easily modifiable graphical representation of the product.
The user can nearly view the actual product on screen, make any modifications to it, and present his/her ideas on screen without any prototype, especially during the early stages of the design process. n Perform

    A CAD model can quickly display an engineer’s ideas in a realistic way. And those models can be used to generate technical drawings that can communicate the information necessary to make the idea a reality. In order to generate a 3D model, designs must start with sketches that are generated within the CAD program. These computer generated sketches will appear resemble hand drawn sketches in geometry (the combination of points, lines, and shapes), but have big advantages over hand drawn sketches. One important difference between a freehand sketch and a CAD sketch is accuracy. The lines of a CAD sketch can be drawn perfectly straight, with start and end points that occur in exact locations in space. By using numeric (dimensional) constraints a line may also be given precise length, placed a specific distance from another sketch feature, or constrained to be oriented at a specific angle from another straight line. By applying geometric constraints a line can be made perfectly horizontal or vertical. If more than one line is being sketched, they can be made perfectly parallel or perpendicular, collinear, or equal in length. Lines can be constrained to be tangent to circles or arcs, and two circles can be constrained to be concentric. In order to precisely model a part, the designer must be able to use dimensional and geometric constraints within the CAD program.…

    In order to use CAD effectively as a design tool, the designer must have the skills necessary to create, edit, and manipulate a 3D model of a part in order to create a realistic representation of an imagined object. In this activity you will build on the CAD skills that you learned in Activity 5.2b Introduction to CAD Skills. You will learn about and use additional tools and features available in most CAD programs and apply your new CAD skills to the creation of more complex parts that will be used in later activities (as components in the assembly of parts) to create complete products (including a complete Automoblox vehicle and a Button Maker machine).…

    5). This process enables the designer to explore the “design space” (combination of possible design ideas for a product) and deliver a design that fits users, which may then be transferred into a real design through development and testing, realising the design (Benyon, Turner & Turner, 2005, p. 41). In the FlightDeck project, this exploration was scoped down to the design and development of a single prototype; this afforded team members an experience into the design of a mobile application.…

    2d Verses 3d

    • 477 Words
    • 2 Pages

    Let me give you an example. Just creating a sheet metal box in the 2D world we would draw up the parts on paper, check our fits and clearances. Everything may look good on paper but you have a thing called human error involved. We might have made a math error or just put down the wrong number on the drawing. That in itself can throw everything off. For one because the prototype shop is going to try and make the parts just the way you have them on the drawing. So if it’s wrong you get the parts back wrong. On the other hand with the help of a good 3D modeling program like Pro/Engineer we can achieve good parts quicker. Let me explain. With Pro/Engineer when you are creating a 3D model, it is created in real space so what you see on the screen is what you are going to get. If you make a change to the model the whole model and drawing changes unlike in the 2D world only the drawing changes. In the 2D world you have to make changes to every drawing. In the 3D world the models are linked to the drawings so if you make a change to the model the drawing also changes. You don’t have to touch the drawings. For…

    3D Printing

    One of these industries is architecture, construction, and engineering. Architects are using 3D printing to save time when putting together their scale models. In the future there will be no limitations to their designs; the reason for this being that construction companies are now experimenting with 3D printing to build parts of buildings. They have started to print using concrete and have been able to print up some wild angles and designs. These were difficult to pull off before because it was hard to make the form to pour the concrete. In the future architects and project managers will be able to work together and print sections of a building in one location, then move and assemble on sight. Just like architects, engineers are using 3D printing to print up scale models of their designs. With the advances in this technology they are able to print these items with moving and working parts.…

    Aerospace Engineer

    My will to become an aerospace engineer comes indirectly from my father. Not that he is an aerospace engineer himself but because he gave me the love of space. Indeed, my father is a formal civil engineer and he spent a big part of his engineer's career to build runways for airports. He used to take me with him on his workplaces when during my childhood. There were many planes taking off and that fascinated me. later, when I was eleven years old, he took me with him in a small plane to show me how the cockpit was.at that moment I decided that I wanted to be a pilot and I did everything in order to realize my dream: I tried to travel by plane as many times as possible.in high school, I was not the best in every subject but I was untouchable in math and physics. Unfortunately my dream was broken after I graduated from high school, as I went to pass a test in the company my father worked for, a company that also formed future pilots, to determine if I had the abilities to become a pilot. Unfortunately for me I did not pass the test because of my eye's problem. Indeed, since I am nearsighted, the testers told me I was not qualified for their pilot program. I was really disappointed but I still wanted to find a job related to aerospace, planes and which fitted my abilities in math and physics. I searched on internet and I found the job that matched all the specifications I wanted.it was aerospace engineering.in my researches, I also found that engineers' job is to innovate, create new things to ameliorate living conditions to make the world better. Those characteristics caught my attention and really encourage me to in…

    When I grow older I want to become an aerospace engineer. Right now becoming an aerospace engineer is my so called “Dream Job”. I think that becoming an aerospace engineer sounds very fascinating. Although becoming an aerospace engineer is not an easy task. All the steps that are necessary to complete to become an aerospace engineer are very hard and very demanding. For instance, you have to go to a good college to get proper education on aerospace engineering. You can't go to some technical school for aerospace engineering; you have to go to a full four-year university. This is due to the fact that you need to have proper education for all a complicated tasks and aerospace engineer has to deal with.…
