In recent years industrial has become heavily dependent on computers for design and assisting with like life situations that are simulated, this may be for safety orientation of for engineering design. With “Prototype” machines, animation is almost essential for simulation of its operation to ensure its design is fit for purpose in its designed environment to ensure it will work, which otherwise will have to wait until built and fitted which may then show design problems. With 3D technology you can virtually show any piece of machinery how it works before the machine is built. This can save money and resources that might go into developing a product that will require major modifications or even have to be disregarded completely.
