The Webel Balls & Boxes worked sample problem is the main first exercise for all attendees of Webel SysMLv1 workshop seminars and SysMLv1 Educational Consultancy web sessions. The task commences at the state of a fresh project created by following your Webel Quick Start Guide for Cameo and MagicDraw PDF slide kit.

The Webel Balls & Boxes task is based on actual coloured balls and boxes props that are used in Onsite Workshop Seminar courses. For Live Online courses and in the PDF slide set images representing the Balls & Boxes were generated using  Wolfram Mathematica.

The Webel Balls & Boxes problem is was deliberately chosen to be a fun example based on just some simple props:

But the concepts explored are crucial for application of SysMLv1 to all real world projects and for capturing system configurations and system variations!

Some key aspects of the Webel Balls & Boxes worked sample problem:

  • Explores the following modelling elements: Block, Property, ValueProperty, Generalization, Association, SysMLv1 Enumeration, InstanceSpecification.
  • Explores redefined properties and redefining properties with default values.
  • Explores SysMLv1 Parametrics mathematical calculations with ConstraintBlocks for those who have Magic Model Analyst® (Cameo Simulation Toolkit®).
  • Has optional advanced exercises exploring deep configuration hierarchies in SysMLv1.
  • Deliberately does not include Ports or any aspects of Behavior (Activities, StateMachines).
It is important that you successfully complete the basic exercises in the Balls & Boxes worked sample problem before moving on to other SysMLv1 topics.

It is recommended that before your attempt the Balls & Boxes worked sample problem you first watch this video after following your Webel Quick Start Guide for Cameo PDF slides:

If you can't attend a Webel workshop seminar course, you can still purchase a Webel SysMLv1 slide kit including the Balls & Boxes worked sample problem:

The worked sample problem is optimised for Magic Cyber-Systems Engineer ® (Cameo Systems Modeler®) but may be attempted in any tool.


Yes, there will also be a SysMLv2 version of the Webel Balls & Boxes worked sample problem

The new SysMLv2 language version uses different terminology, has some different concepts, and uses a more powerful and more flexible mechanism for handling redefinition of values. A separate Balls & Boxes covering the topic for SysMLv2 in Cameo is planned.
