Stoyo,

I'm just working my way through all of this and was looking for AllowSplitArrows and can't find it...  I've done a search in the documentation and the flowchart properties.

Hi Paul,

We have some progress with that, try this version:

https://mindfusion.org/_temp/FlowChart.NET.zip

- dragging the middle point in two-segment cascading arrow will insert new segments
- there is a MergeThreshold property available now (0 by default); increase its value to let users merge segments without exactly matching the merge-point coordinates. This property depends on MeasureUnit.
- regarding the "last segment going away from the node" feature - try doing that with auto-routing. Now there is a RerouteArrows.WhileCreating flag that can be applied to RoutingOptions.TriggerRouting to show the arrow route while an arrow is drawn. There is a similar WhileModifying flag, but it's not implemented yet.
In addition, if you use anchor points, set RoutingOptions.Anchoring to Reassign.

That last feature make arrows a little jumpy because a small change in the mouse position could lead to a big difference in the route, we'll see whether we can improve this.

Stoyo,

Is it possible to get a source-based copy of this latest?

Thanks,
Paul.

I've recompiled using the new code and made the changes you recommend in your posts.

It looks better (especially the threshold on the merging of points) but I still have a couple of issues, illustrated by the following screenshots:

After creating each arrow I set AutoRoute to true.  I then get an exception in PointCollection.this[int index].get:

return (PointF)List[index];

(watch details and callback at end...)

This is called from Arrow.getCrossings():

...
for (int test = 0; test < arrow.SegmentCount; ++test)
{
PointF testPt1 = arrow.Points[test];
PointF testPt2 = arrow.Points[test+1];
...
