If you've followed the trail so far, this should be completely clear. The only noteworthy thing is that this conversion means the HumidifiedRoom is "sending" a measurement of the humidity as a percentage HumidityPct not a relative humidity.

Let's now see how the Humidifier handles that HumidityPct to try to reach a targetHumidityPct.

BDD & IBD: Humidifier
Notes
[ASSERTION]{STRONG} Webel vs SysPhS-1.1: Annex A.5: Humidifier: It is assumed that "vapor" is a volume rate corresponding to the rate of consumption OF HEATED LIQUID WATER (from a tank) used to create the vapor.
[MODELLING, NAVIGATION, PATTERN, TIP, TOOL]{STRONG} UML/SysML: Navigation: Try to offer a way out of a diagram (usually up a hierarchy, but possibly across) using a navigable symbol (linked to a diagram) and/or a diagram symbol. Avoid "cul-de-sacs"!
[MODELLING, PATTERN, TIP]{RECOMMENDED} SysML: When using Property::defaultValue and Property::redefinedValue to carry a "shadow hierarchy" of redefinitions across an entire system hierarchy, considering using a user-defined keyword such as «configuration» or «scenario» on each redefining Block
[CAPABILITY, FEATURE, TOOL] MagicDraw/Cameo: Supports embedding of one or more Diagrams in another via the Diagram Overview feature. Awesome!
[CONVENTION, DISPLAY, STYLE, TIP]{STRONG} Consider creating a "focus" Block Definition Diagram (or Class Diagram) for each main Block (or Class) with expanded feature details and relationships to at least nearest neighbours
[NAMING, TIP]{RECOMMENDED} Suffix the "focus" BDD for a Block with .bdd so that it won't clash with a corresponding IBD on diagram export.
[DISPLAY, STYLE, TIP, TOOL]{SUGGESTED} Style: use line width 2 or 3 on the border of the "focus" element in "focus" diagrams (such as the main Block or Class of a dedicated Block Definition Diagram or Class Diagram)
[CONVENTION, NAMING]{STRONG} Webel: If you must name your Ports or Pins, name them simply 'i', 'o', or 'io' to indicate direction UNLESS you have to indicate a special role like 'iRole', 'oAuxiliary'. DO NOT use Port names like 'input', 'output', etc.
[CAPABILITY, FEATURE, STYLE, TIP] MagicDraw/Cameo: Consider showing the constraint parameter name and type label inside the small rectangular parameter symbol on SysML Parametric Diagrams!
