Introduction

When you are creating models, there are common scenarios that occur. You can create bits of models, called  "patterns" to use in these scenarios.  You can then re-use the model patterns whenever the scenario occurs. Patterns can be:

• controls
• groups of controls
• portions of models.

A pattern is any solution that is useful and reusable, from very simple methods to more sophisticated model-fragments.

This topic contains pattern suggestions for some common modelling scenarios.
