Hi Domenico,
We have a support to achieve your requirement (“Node with multiple connectors”). Multiple connectors between two nodes can be achieved by using ConnectionPort. We have created the sample to represent this. Please refer to the sample from the attachment.
ConnectionPort:
ConnectionPort is used to connect the Node with LineConnector on a specific point. The ConnectionHeadPort and ConnectionTailPort properties of LineConnector can be used to specify the ports to be used for connecting to the nodes.
For more details about ConnectionPort please refer to our online help documentation link.
