Parametric Diagrams are 2-dimensional, and the placement (or "ordering") of ConstraintParameter symbols on the boundaries of symbols for ConstraintProperties - or on the framed boundary of a ConstraintBlock context itself - need not be bound in any way by the ordering of the constraint parameters on a related ConstraintBlock. They are completely different ways of thinking!
In MagicDraw SysML Plugin and Magic Cyber-Systems Engineer ® (Cameo Systems Modeler®) you can order ConstraintParameters on a ConstraintBlock using the specification dialog or on a Block Definition Diagram (BDD); such a 1-dimensional ordering need not have any bearing at all on how you organise the representation of those ConstraintParameters as symbols in a 2-dimensional SysML Parametric Diagram. None at all.
Dr Darren says:
Take advantage of 2-dimensional SysML diagrams to represent networks and flows as best fits the modelling purpose.
