A connection point is a special point on a shape that you can "glue" connectors and other shapes to. It looks like a blue x. When you glue a connector or shape to a connection point, they stay connected, even if one of the shapes is moved. Use connection points when you want connectors or shapes to stay connected to specific points on a shape.
Add a connection point to a shape
Tips: Be sure the shape is selected before you add the connection point. The selected shape has a green, dashed border. Connection points are created only for the selected shape, even if the pointer is positioned over a different shape.
