Remarks

To navigate to the model element or relationship that the shape represents, use ModelElement().

Important subtypes include:

Diagram – represents a collection of shapes and connectors. The content of a Diagram is persisted in a .diagram file. If you specify a diagram class in your DSL Definition, it is derived from this class.
NodeShape – represents a shape that has a non-zero area, not a connector. If you specify shape classes in your DSL Definition, they are derived from NodeShape.
BinaryLinkShape – represents a line between two NodeShapes. If you specify connector classes in your DSL Definition, they are derived from this BinaryLinkShape.

For more information, see [redirect] How to: Navigate and Update a Diagram.
