Now a day the designing product has develop to
by using speed and accessory and also with low price to competing with the world technology development that
why computer progress are needed to catch up with the
world.

            Start with 3 dimension model and we would do an
experiment on the 3D model in the computer, if there was
a problem we will use the mistake to develop the model and
experiment it again until there are new more problem.

            After the 3D model has pass the experiment to 2D
drawing for checking the product and in the same time 3D
model can be used to make the progress to control the
machine to build the product with accessory and speed.

            In the opposite way 2D model can be used to make
3D model and use CAE for the experiment then used CAM
software control the machine to run the production process
and support such as mold, prototype and checking fixture.

            From all of what I have it all work out in the computer
that why we can used this progress to design and make the
product with out using any supply so we can decrease the
cost of designing product and also we do not need to make
the any port to do any experiment that also lower the cost
of making the product, also all the product are in the
computer So we can sent the product to the client easier and
faster and also safe by using the security system, and this can
also decrease the cost of delivery.
