In this recipe, you will learn how to operate and utilize an existing iLogic assembly of a ladder. You will become familiar with the iLogic browser and how you can access and edit rules to construct models. You will also make changes to the assembly using the predefined iLogic form.

iLogic itself is a large topic, but this chapter aims to introduce readers to the core functionalities. Here are some common areas where iLogic is utilized:

• Suppress or unsuppress parts or features
• Control assembly constraints
• Run multiple operations on a single input
• Make configurations
• Update iProperties of models
• Work with iFeature, iParts, and iAssemblies
• Control drawing borders and title block information

As with most features and functionality in Inventor, there is a recommended workflow. For iLogic, this is as follows:

1. Create and define the model.
2. Create the iLogic rules.
3. Set rule triggers...
