Webel: SysML1.7: Port contract matching is Feature-based, not Type-based. There's nothing particularly magical or special about use of an ~InterfaceBlock on a "conjugating" SysML Port, it's just a convenient way of managing one-to-one Feature matching!

MagicDraw/Cameo v19SP3 vs SysML&SysPhS: GOTCHA: Will NOT correctly export a SysML-1.6 «~interfaceBlock» to Modelica (but does cope with a tilde ~ prefix in the name of a plain InterfaceBlock)

SysPhS-1.1: Annex A.5: Humidifier: Use of UML-style direct Port conjugation not permitted since SysML-1.6, prefer ~InterfaceBlock type-based conjugation (example requires migration)

[HISTORICAL] SysML: Some users employed the ~ tilde prefix for a conjugated Port type long before it was introduced for ~InterfaceBlock and you MAY use it to name a regular Block that is not an ~InterfaceBlock

Cameo: SysML: When sending a Signal via a Port with a SendSignalAction, Cameo does not care what the directed feature directions of the Signal receptions on the Type of the Port are (even if it should).

A "staging" BDD for defining the flows, ports, and item properties on blocks to be used in an IBD does not have to be a "work of art" if it is not intended as a final presentation diagram.

Typing a "standard" Port by an InterfaceBlock or ~InterfaceBlock IS allowed AND can be useful; typing a FullPort by an InterfaceBlock or ~InterfaceBlock is formally allowed but not so useful, because it would have no parts or behaviors to do anything.

Proxy ports are always typed by interface blocks, a specialized kind of block that has no behaviors or internal parts.

SysML Block Definition Diagram (BDD)

MagicDraw/Cameo 19SP3 still supports the DEPRECATED UML Port conjugation (but it is recommended here that you DO NOT use it, even though there might be future migration for such directly conjugated Ports).

Until tool support for ~InterfaceBlock comes you have to make a decision: (1) Bake your own «~InterfaceBlock» then deal with clashes when tool support comes; (2) stick with the DEPRECATED UML conjugation (not nested-port friendly) and await migration.

Avoid mixing flow properties on the Type of a Port with directed features (operations and values); One distinguishes between "ports with flows" and "contract ports".

Conjugation is specified by a constraint giving the features of ~InterfaceBlocks according to those of their original InterfaceBlocks ... It is expected that tools conforming to this specification automatically create features of ~InterfaceBlocks.

InterfaceBlock ... for example, in flow properties are conjugated as out flow properties and provided features are conjugated as required features.

The ~InterfaceBlock stereotype (shall be pronounced: "conjugated interface block") is a specialization of InterfaceBlock that has the same features as its original InterfaceBlock except that its DirectedFeatures and FlowProperties are reversed (conjugated

Conjugation in SysML-1.7 is Type-based: InterfaceBlock, ~InterfaceBlock, and DirectedFeature

[HISTORICAL] MagicDraw/Cameo 19SP3: Does NOT yet support ~InterfaceBlock [NOW SUPPORTED in 2024x Golden]

The mechanism for conjugated Ports has been changed in SysML 1.6, it now conjugates the Type! If you are using an InterfaceBlock to type a Port you can conjugate that 'original' on another Port by typing it with an ~InterfaceBlock.

SysML-1.6: Figure D.19: It's not clear why 'Port:~FuelTankFitting' (an ~InterfaceBlock conjugation port) does not match 'Port:ICEFuelFitting'

SysML: Typing a Port by an InterfaceBlock or ~InterfaceBlock does NOT imply that the Port is a ProxyPort (but ProxyPort must be typed by an InterfaceBlock or ~InterfaceBlock)

For Blocks and Interface blocks with one or more FlowProperty items, choose a direction convention and use it across one project.
