Simulations - What software is #1

[HULK]

Hello,



I need to make a video similar to this: http://www.youtube.com/watch?v=Q9SIYuN9aDU<a href="http://www.youtube.com/watch?v=Q9SIYuN9aDU" target="_blank" target="_blank">
</a>

to move components in my assemblies to show motions.



From past experience with other software
