Do engineers have a program where they can import the 3D CAD drawing and test it for physics and desired performance? Is there an industry standard simulation software for these things? If engineers design an engine or parts of an engine what is the simulation environment they test it in? Please let me know your ideas and mention any software you might have heard of that is used in the (mechanical/electrical/au... engineering industry - from laying out oil hoses for a piston to creating a rotating crank for that piston. Integration of circuits and electronics with this mechanical simulation would be ideal as well. I would like to design the "under the hood" portion of the car with this software (designing the body would be nice too). I suppose you would be able to design something like a toaster, shaver, iron or a lawn mower as well. Any ideas are greatly appreciated!!!!!!
