Hi Jiss,
Thank you for using Syncfusion products.
You can use Ellipse and Rectangle classes for creating diagram shapes ellipse and rectangle.
Please use the following code snippet.
[C#]
// Creating Ellipse
Ellipse ell = new Ellipse(30, 30, 150, 50); this.diagram1.Model.AppendChild(ell);
// Creating Rectangle
Syncfusion.Windows.Forms.Diagram.Rectangle rec = new Syncfusion.Windows.Forms.Diagram.Rectangle(90, 190, 70, 70); this.diagram1.Model.AppendChild(rec);
