Questions about ConvextSweep and Ray Sweep

[Dr.Shepherd]

Hi, I want to make the thing below:
Once an object hits the ground, a hinge joint is produced at the contact point between the object and ground.

So first I need to get the contact point, is it? I read around and it seems that ConvexSweep and Raysweep would do what I want?

Could anyone give me some advice on it or tell me which demo I may get some information?

Cheers.
