SysML Part Property representations

The notations that apply to an Internal Block Diagram (IBD) also apply (where relevant) to the internal structure compartment on a Block symbol in a BDD:

SysML-1.6: 'A part or value property is always shown on an internal block diagram with a solid-outline box.'

Here we see the part properties screen:Screen and speaker:Speaker shown in both the parts compartment and as symbols in an internal structure compartment. There are pros and cons of each form. One advantage of the symbol form is that one can make connections; another is that in SysML one can expose information about the features of the Type that types a Property on a Property symbol, which very nice capability we'll see used often later during these tutorial trails.

[CAVEAT, DISPLAY, TOOL]{INFORMATIVE} MagicDraw/Cameo: Does not show the “structure” label at the top of an internal structure compartment.

Snippets (quotes/extracts)

[SysML-1.6] A property typed by a SysML Block that has composite aggregation is classified as a part property, except for the special case of a constraint property ...

[SysML-1.6] A compartment with the label “structure” may appear as part of a block definition to show connectors and other internal structure elements for the block being defined. This compartment may contain any of the graphical elements of an internal block diagram

[SysML-1.6] A part or value property is always shown on an internal block diagram with a solid-outline box.

[SysML-1.6] Part, reference, value, and constraint properties may be shown in block definition compartments with the labels "parts," "references," "values," and "constraints" respectively.
