Here is the FAQ page of the SysML Tools.
-
When I open my old model with version 1.0 of SysML editor, an image appears on the connectors shown in my Internal Block Diagram, as well as a new label, and I can't remove them.
-
This is due to a new functionality we have added in this version : ItemFlow.
To solve this problem, you have to 'delete from diagram' the connector and then do a "Restore Connection" on one of the element it was bound at.
