Drawing Line

I have a question.

Link takes points as a parameters. But i need to drawn to line like link. And i want to use routing. For example go.Link.Orthogonal.

My question is that what is the equivalent of this ?

[Link takes points and Orthogonal routing] ===> Node? Shape ? Geometry?

I do not understand what you want. Perhaps a few small screenshots or sketches would help demonstrate the behaviors that you want. Please show the results at each step of any state changes.
