Subsequent tutorials expand on this information, and show you how to create even more intelligent models, still with only very simple rules. This tutorial will introduce you to the most important aspects of working with iLogic rules, and show you how to create simple (but powerful) rules that control the modeling of a simple part. A rules-enriched model is therefore far superior to a simple parametric model. Defining the relationships between all objects in a design makes it possible to update the model completely, correctly (according to the rules), and automatically when input parameter values are changed.

Equations or relationships can be defined between the parameters, properties, attributes, features, components, or any other aspect of the design. These “conditional equations” are not limited only to the parameters, but can involve all aspects of the design. Using rules in a parametric model allows for conditionally-defined equations. These parameter values can be input directly by the user, or can result from fixed equations involving other parameters or even linked spreadsheet values. Traditional parametric modeling involves driving geometry with dimensional parameters. These rules work along with the parameter update mechanism of Inventor, and allow you to include much more sophisticated design intent into your models. iLogic extends the computational capabilities within Inventor to include rules.
