Software that simulates a wooden drawing doll?

I am learning to draw figures, and a wooden doll (pictured below) is a lot of help. But I'm having issues keeping a specific angle in regards to the doll. Even a little shift in position can make the drawing off.

Is there a program that provides a 3D dummy figure which can be adjusted to any position like a wooden doll? This would enable me to keep the angle exactly the same without having to worry about movement.
