SysML: Cameo Systems Modeler: A ValueType that does not extend Real might not always simulate correctly when used to type a constraint parameter of a ConstraintBlock (in a SysML Parametric Diagram) or to type a parameter (in a SysML Activity Diagram)!

Webel: SysML4Mathematica: Cameo Systems Modeler: Can perform calculations with a custom Quantity ValueType (for Mathematica) directly, but DOES NOT perform units-aware algebra (no automatic conversions)

Webel: WISHLIST: MagicDraw/Cameo: UML/SysML: Ability to freeze the Feature lines shown on symbols under Edit Compartments so that the diagram does not "break" when new Features are added elsewhere (reduce graphical coupling)

Cameo Simulation Toolkit: You can assign the results of simulations calculations on instances to the default values of properties of the Classes/Blocks that type the instance.

UML/SysML: MagicDraw/Cameo: WARNING: If you assign a value to a Slot for an untyped Property then assign a ValueType later it will DELETE your assigned value! Assign a type first .

SysML Parametrics: You can use custom stereotypes keywords «i» and «o» to indicate value properties that are intended to be used as (i)nputs and (o)utputs when bound to constraint parameters for SysML Parametrics

MDSysML/Cameo: Unless a custom ValueType is otherwise specified through specialisation it is behaves like a Real for the purposes of data entry for value properties typed by that ValueType

MagicDraw/Cameo: A structured ValueType can have value properties (each typed by a ValueType), but they list in an 'attributes' compartment (not a 'values' compartment)

Computed category membership test values are sometimes adequate and can prevent Class/Block explosion. However, a dedicated Class/Block encapsulating a clear domain concept offers a clear documentation point and can carry other characterising features.

The constrained properties, such as mass or response time, typically have simple value types that may also carry units, quantity kinds, or probability distributions.
