	Hello, Stoyo. I tried to use CopyToClipboard call and after that I set the breakpoint in the public virtual DiagramItem Clone(bool clipboard) call in the DiagramItem class into your source code. And I see that the following returns null Code ConstructorInfo constructor = GetType().GetConstructor(new[] { GetType() }); My class has th default constructor Code public class TechnologicalOperation: TPDENode, IComparable { public TechnologicalOperation(): base() { Type = NodeType.SimpleProcess; HandlesStyle = HandlesStyle.Custom; } } Where is the problem?

	The TPDENode class also has the default constructor Code public class TPDENode: ShapeNode { public TPDENode(): base() { CustomDraw = CustomDraw.Additional2; InputNumber = 0; OutputNumber = 0; Type = NodeType.Bus; m_ShadowProps.ShadowDepth = 5; HandlesStyle = HandlesStyle.Custom; }

	Hi, That code tries to get a copy constructor. You can either override the Clone method, or add copy constructors to your classes: public TechnologicalOperation(TechnologicalOperation prototype) {...} public TPDENode(TPDENode prototype) {...} I hope that helps, Stoyan

	Thanks. Clone methods had been overriden but some classes doesn't have the copy constructor
