Parametric diagrams are used to express constraints (equations) existing between value properties. They are a restricted form of internal block diagram and represent constrained use in a particular context.

The most important elements are Constraint Properties and FlowPorts composing the ConstraintBlock, as well as their relationships modeled using Connectors or Item Flow links.
