SysML Parametric Diagram

SysML Parametric Diagram⌘

• Parametric diagrams model a network of constraints on system properties to support engineering analysis, such as performance, reliability, and mass properties analysis.
• Parametric diagrams is a restricted form of internal block diagram that includes usages of constraint blocks.

Constraint Property⌘

• A constraint property may be shown on a parametric diagram using a rectangle with rounded corners.
• This graphical shape distinguishes a constraint property from all other properties and avoids the need to show an explicit «constraint» keyword.
• A value property may optionally be shown by a small square box, with the name and other specifications appearing in a text string close to the square box.
