SysML Block. parts compartment.

[Jinseok Jeong]

Hi. 

I have a question about parts compartment of SysML Block.

I'm curious why the composition relationship between blocks doesn't appear in the parts compartment.

For example, as you know, in the HSUV diagram of the SysML Example, the "Power Subsystem" block has a Composition relationship with both the "FuelTankAssembly" block and the "InternalCombustionEngine" block.

However, even when the 'Suppress parts' option is turned off in the Format settings of the Power Subsystem block, a part list including "FuelTankAssembly" and "InternalCombustionEngine" doesn't appear.

Are the contents of the part compartment written through the "Add part" feature and the composition relationship on the diagram not related to each other?

Hello,

In StarUML, relationships are not redundantly represented in compartments. This applies to both SysML and UML.

While there's no definitive answer, I believe it's clear in StarUML to differentiate between Features and Relationships and not represent them redundantly in a single compartment.

Thank you,

Thanks for your reply, I understood how part compartment feature and composition association are handling in the StarUML.

However, I still believe that those two should be interconnected in BDD.

I understand that the purpose of Parts properties is to describe the composition relationships of blocks.

What if there was an automatic creation of 'Part' when drawing Composition Associations between blocks in BDD?

Similar to how, in IBD, dragging and dropping a specific block automatically creates a part.

The current handling in StarUML leads to an issue where the automatically generated Part properties content, when dragging and dropping a specific block in IBD, does not align with the content written when creating Composition Associations in BDD.
They exist separately, causing inconsistency.
