Piston - Designed in Autodesk Inventor

I decided to share this assembly of a piston with connection rod now, as this is a part of my bigger project.

A piston is a component of reciprocating engines, reciprocating pumps, gas compressors and pneumatic cylinders, among other similar mechanisms. It is the moving component that is contained by a cylinder and is made gas-tight by piston rings. 

In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. 

In a pump, the function is reversed and force is transferred from the crankshaft to the piston for the purpose of compressing or ejecting the fluid in the cylinder.

Does CAD make better cars than human designs?

Did you ever spend hours as a kid sketching pictures of cars, devising design variations and more streamlined looks? Or carving derby cars from blocks of wood? Pencil and paper have gone the way of the dinosaur since then: Modern automotive designers and engineers have a powerful tool Computer Aided Design (CAD) at their disposal to help bring their ideas to life and facilitate the process of imagining, designing and refining them. CAD software is also used in packaging, shipbuilding, aerospace design, industrial and architectural design, film animation and many other applications.
