postheadericon Use Of A Specialized Engineering CAD Design Program Made Easy






by Melker Fredriksson


Now that computers are such a part of everyday lives the programs that are used become more tuned to specific needs. So it is with the very specialized engineering CAD design program which MCAD supplies to the industry. This software can be used to create and develop different mechanical tools for use in specialized areas such as search and rescue.

With standard engineering parts like bolts, screws, and washers already in the database, it allows new parts to be created and blueprints produced. Parts can be saved with part numbers and referred to again at a later date. Frequently used parts such as levers and joints could be created and then called upon to fit anywhere within the finished article, and the sizes amended to fit each place.

The nice thing about this software is that the user can start with a rectangle or circle on a flat surface. This can then be manipulated using the mouse into a three-dimensional object. All the dimensions may be adjusted to suit. By using other circles or rectangles, the part can have slices removed or holes drilled. The edges might be softened using a fillet tool which allows the curves and slopes to be adjusted for each edge.

When you have an original shape, you can then add another shape and work on that too. It is possible to add a circle to an original shape and by dragging the circle with the mouse, this then turns into a pin on the original shape. You can place a hole inside the pin and the database contains all the necessary data to create the correct hole for the dimensions required. All dimensions can be adjusted as the work progresses and this will also change the dimensions on any blueprints already created.

Once you have created the parts, they can be fitted together on the screen, allowing a work through of the actual build process. Nuts, bolts and washers can be added from the database as required, as can locking washers and other regular fittings. The program then allows for a test on the movement of hinged or working parts to show if there is any collision between parts. If collision is found, the parts can be adapted at this point in the program and all the information relating to that piece will be changed accordingly.

Working in this way, allows a business to create anything from nothing. It is then possible to work through the actual build process. The article can be seen working at any stage through the process and any necessary adaption to the parts made at any point. Finally, it is possible to see the finished article working in full three-dimensional view.

During the whole process, the computer calculates the amount of material used, and the weight of each individual component. It keeps a log of all the component parts and the different sizes of standard data parts used. It also allows parts to be recalled for fitting in other areas of the tool.

The use of a CAD design program that is this advanced, means that its possibilities are endless. Theoretically, there should be no job that can not be done through lack of the proper tool. The system gives the means to design a product which has no build problems and works perfectly.
