I want to use this with an AdornerLayer. At the moment I have this (which works as far as it goes when the BezierSeqment is populated)

public class PathAdorner : Adorner

But I want to use Thumbs rather than just drawing in OnRender(). I know the principal is to create the Thumbs and add them to the VisualChildren collection and to place them in the ArrangeOverride method but can't work out how to get the correct placements.

Not sure I'm fully understanding what you want.

Why ArrangeOverride? Why not just add the thumbs to the AdornerLayer of the path?

I haven't actually played with this myself yet. (It's a to do item for my code <g>)

But I did load the code here:

and I "think" maybe it might be doing what you want???
