Hi A., and all,
can I make the arrow from user to thing2 be to the center top of the rectangle as it is in thing1?
Not yet... (expect a possible proposal: see below) due to the management of nested element...
Here some other elements of answer...:
Here is a proposal, using sub-diagram:
rectangle thing2 [
user --> thing1
user --> thing2
If that can help,
If I can say briefly what I am trying to do.1. have a "high-level" deployment diagram with "micro services" identified by a rectangle.2. then have a Level -1 detail where I expand the components inside the microservice and show how they interact with other micro-services. So I want elements of the sub-diagram to have arrows out to the rest of the diagram.
Perhaps, for that you can see on C4-Architecture, see:
