Geneva mechanism simulation

NX cad has many tools similar to catia but its good at rendering and appearance. I like nx cad by the way it looks and realistic rendering makes me more deviated towards nx. So I prefer NX compared to catia. But catia is anyway good if you have good experience in it. Gears are used for transmission of power. Geneva mechanism is used in movie theatres to move reels and these days this mechanism is used in automations.
