Hi John,
Thank you for the update.
GraphicsPath is a series of curves and lines.
So if your intention is to create a node consisting of several lines and curves using the array of points you have then it can be done by customizing the Group Class and creating a node consisting of several lines ,curves etc...
Kindly take a look at the attached sample.
In this sample, the Group class is customized and several closedcurve and line nodes are appended to form a group in this custom class. Then this group is appended to the DiagramModel under the form load event.
You can download the sample from the webpage link given below,

Thanks & Regards,
Ramya.
