Dot Notation

[rothnic]

Does EA support "dot" notation? I cannot find a reference to it.

From the SysML 1.3 specification:

A pathname dot notation can be used to refer
to nested properties within a block hierarchy. This allows a value property (such as an engine displacement) that may be
deeply nested within a containing hierarchy (such as vehicle, power system, engine) to be referenced at the outer
containing level (such as vehicle-level equations).

So a composite diagram or IBD could have a part of:
sb1:Subsystem1, which has a part of
sb2:Subsystem2, which has a part of
sb3:Subsystem3, and so on...

Instead of showing a sb1 rectangle, with a sb2 rectangle inside of it, and a sb3 rectangle inside of it, if you wanted to call out sb3 specifically in the context of the Block's ibd, instead you could have:

sb1.sb2.sb3:Subsystem3
