re-route overlapping arrows

I have a diagram that represents several artifacts that have relationships defined between them.  two artifacts can have more than one relationship between them (many to many).  The arrows that represent the relationships currently overlap so that it appears that only one relationship exists.  How can I ensure that the two or more arrows that connect to the same node do not follow the same path?

Hi,

At this time the control cannot separate such arrows automatically. You could try defining anchor for the nodes and allow only one arrow to be attached to an anchor point. Or after creating the arrows, explicitly set the positions of their first and last control points.

Hi,

You can do that by handling the ValidateAnchor event. Check if another arrow already has that anchor point index as a OrgnAnchor or DestAnchor value, and if it does, return false from the event handler.

It seems to work, although arrows are not routed very well. Thank's.
