How can i simulate a Rubber band?

[johnnychang]

Hi,

Crank up the amount of distance constraint iterations, then reduce the stiffness in the distance constraint's component. 

Simulating rubber bands is actually extremely easy, the hard thing to do is the opposite: rigid materials.

cheers!

And there has a problem,in the component ObiPinConstraints when i click Add Pin Constraint there is no response.
