Hi Emoscosocam,
Thank you for using Syncfusion products.
1. Drawing a node with rounded edges:A node with rounded edges can be created by using the class RoundRect. Please refer the below code snippet to achieve this:
Syncfusion.Windows.Forms.Diagram.RoundRect rr = new Syncfusion.Windows.Forms.Diagram.RoundRect(100, 100, 200, 100, MeasureUnits.Pixel);
rr.CurveRadius = 20f;
this.diagram1.Model.AppendChild(rr);
Please refer to the below sample that illustrates the same:
