SysML: Using redefined Property and Property::defaultValue to create deep hierarchical value configurations of "initial values" configurations for SysPhS simulation is notoriously fiddly and requires experience and patience. Better tool support is needed!

What is needed is some kind of dedicated GUI worksheet for managing an entire "shadow" extension of a Block hierarchy and the ability to offer and edit possibly redefined values for a specific system configuration or scenario.

Unfortunately, given that SysMLv2 will have a nicer built-in way of addressing deep hierarchical system configurations, tool vendor will have little impetus to improve this in tools for SysML-1.6/1.7.

In the meantime, it basically has to be done "by hand" as shown in:

Annex A.5: Humidifier (with Units)

A procedure is described here:

MagicDraw/Cameo: HOWTO: Create a redefining value property with a default value using drag-n-drop

This tip can also help:

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

This improvement would also help:

WISHLIST: MagicDraw/Cameo: Ability to set project-wide option to NOT set the multiplicity of a redefining Property to [0..*] on using drag-n-drop when the redefined (dragged) Property has Multiplicity
