I was wondering if SSDE allows to show directionality of an interface on a topological diagram, similar to what can be done with flow ports and item flows in SysML. As far as I saw, Interface Usage Links only connect two Interface End Usages, but don’t specify the direction of what is passing in the link. Is there a way to add an arrow head at the end of a link? It would basically work like a Function Interface.
InterfaceUsages are not directed in the ECSS ETM 10-23 Model so far. Neither have InterfaceEndUsages (i.e. “Ports”) have input and/or output flags. Hence the SSDE doesn’t support that. I suggest you raise an issue if this critical to you.
