This page shows (for purposes of historical reference only) an OBSOLETE early attempt at re-appropriating Unified Modeling Language (UML®) for port-based systems engineering. Please see now instead for latest Systems Modeling Language v1 (SysML®) !
Shows the “anatomy” of neutron beam instrument assembly blocks with parts, custom UML2 notation for neutron and air flowports, and control ports.
Note that this notation precedes the introduction of the early Systems Modeling Language v1 (SysML®) "FlowPort" (which is now achieved since SysML1.4 using FlowProperties on Block).
