Custom Gizmo/Handle similar to Off Mesh Links

Hi All,

I am building my own pathfinding algorithm for use within Unity Free and was wondering what the most elegant solution to displaying something similar to Off Mesh Links in the scene view.

I have tried using the Handles.DrawBezier command with a from empty object to another empty object similar to:

Code (csharp):

1. Handles.DrawBezier (jh.transform.position, jh.endTransform.transform.position, Vector3.up, Vector3.down, Color.white, null, width);

But the tangents seem incorrect, the beziers do not start in the up and end in the down position. I have tried all sorts of variations with bad results. You can see what I am seeing here or in the link to the image below:

If anyone has a better idea on how to accomplish my goal I would love to hear

But at the same time, why would this code draw such an incorrect bezier curve?

Thanks!
