Computer Aided Design
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 design (CAD) involves creating computer models defined by geometrical parameters. These models typically appear on a computer monitor as a three-dimensional representation of a part or a system of parts, which can be readily altered by changing relevant parameters. CAD systems enable designers to view objects under a wide variety of representations and to test these objects by simulating real-world conditions.
A CAD system is a combination of hardware and software that enables engineers and architects to design everything from furniture to airplanes. In addition to the software, CAD systems require a high-quality graphics monitor; a mouse, light pen, or digitizing tablet for drawing; and a special printer or plotter for printing design specifications.
CAD systems allow an engineer to view a design from any angle with the push of a button and to zoom in or out for close-ups and long-distance views. In addition, the computer keeps track of design dependencies so that when the engineer changes one value, all other values that depend on it are automatically changed accordingly.
CAD is a type of software used for creating blueprints and schematics. CAD software is used in construction, engineering and other industries that use technical illustrations. CAD programs produce designs in 2-D, 3-D, or both, depending on the specific software. Many companies make CAD software-which ranges from open-source to extensive commercial packages-and its use provides several benefits.

There is the variety of use the computer aided design (CAD) includes, the design of goods used by consumers or other products, design of tools and machinery, building floor plans and for the detailed engineering designs. CAD is also widely used to produce computer animation for special effects in movies, advertising

    A part programme is coded using coordinates to give a detailed set of directions to be read by the machine control unit and then followed by the machine tool. When creating a part programme, first of all the programmer must look at a detail drawing to tabulate coordinates and create an operation plan which will include a tool list and materials – this can all be very time consuming and can leave much room for error. Any incorrect code in a programme could lead to errors in the machined component, for example if a datum point is not set in the right place then only part of the component may be drilled/milled in the wrong place; errors in the finished component will mean the entire written programme will have to be thoroughly checked through again, which again is very long and mistakes in the code are not easily identified by the same person who wrote it. If the error is so small the fault in the part made may go unnoticed until put into the final assembly – leading to malfunction. A much more efficient approach to creating a programme would be for the programmer to create a CAD drawing which software such as CIMCO can use to generate a code all by itself. Simulation using CAD can be used for testing a design before letting the programme make it straight away, this makes for less redrafting and delays, therefore saving time. When sent a CAD drawing from a client, it would be quicker to open them using a software – like CIMCO – to generate a tool path for use immediately rather than using the CAD drawing with dimensions to print as a detail drawing to then tabulate etc. Complex shapes and tool paths such as curvy three dimensional designs (for example see figure 1) are much more achievable using 3D modelling because there may be need for more than one tool path at a time which would not be very fun to programme manually. There are some…

    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).…

The fixed costs of Polymold will increase by a large amount due to the new computer cost. This is a negative effect on the company but it should not be taken as too big of a threat. The biggest threat is the competitors in the industry beginning to increase their own structures and strategies in making the product at the most efficient way possible and the consumers would like to receive the best product possible.

    Traditionally Building Projects were illustrated with manually created drawings, information was added to these illustrations by using motes and specifications. As CAD technology progressed this system became automated, though the output remained the same. The development of the Building Information Modelling methodology has created a new way of thinking and working. It gives us ability to model with objects and minimizes tedious drafting by allowing one 3D object handle multiple 2D representations when placed in an object. The coordinated data represented in the model allows us to visualize and analyse designs and make better informed decisions.…

    Throughout the last few years, technology has been improving the lives of people from all walks of life and all fields of study. One of the big pieces of technology in the civil engineering field today is computer aided drafting. AutoCAD is a computer aided design software for the 2D and 3D design of certain objects or places. Computer aided drafting is widely used in the civil engineering field because of its ability to plan sites a lot easier then hand drawings, it can help design a lot of engineering supplies, and is constantly upgrading. Up until a few years ago, civil engineers would hand draw their design plans which could take a while. Computer aided drafting makes this process faster and easier. It can also lay out sites, roads, sidewalks, bridges and other engineering items. There are constant upgrades to computer aided drafting being made every year to improve the system and help civil engineers.…
