Drawing an arc by three reference points

[alex23]

I think that what I am trying to achieve is exactly what was asked in this post:

Reference point driven arc model line using Dynamo

Is there a node (built-in or package) or any other way, to create a Start-End-Radius Arc model line? To clarify I trying to create a reference point driven arc using dynamo to connect the reference points. Thanks!

In the end they don’t seem to find a solution neither.
