A little help?

I remember back when I had gmod 9 I had a tool gun that let me take a prop/ragdoll and made it so the camera followed it while the prop/ragdoll could rotate & move freely I could also move the camera with the mouse. If anyone knows what addon it was or how to do this in gmod 13 I would greatly appreciate it.
