iLogic Tutorial From Autodesk – 01

An iLogic Tutorial from Autodesk

The following ilogic tutorial is the first of three ilogic tutorials that were part of the Autodesk Subscription Bonus Pack 2010. The files needed for this and the next two ilogic tutorials can be downloaded here:

Unzip the file and save it to a location where you can find it. The default location is: C:UsersPublicDocumentsAutodeskInventor 2011Tutorial FilesiLogic Tutorials

The sample files are in 2010 format, so if you do not have 2010 with iLogic (subscription only), you are out of luck. A shame they did it that way, but it is very likely that 2011 will have iLogic built in.


This iLogic tutorial will provide you with a hands-on introduction to the Autodesk® Inventor® iLogic Extension. iLogic extends the computational capabilities within Inventor to include rules. These rules work along with the parameter update mechanism of Inventor, and allow you to include much more sophisticated design intent into your models.

Traditional parametric modeling involves driving geometry with dimensional parameters. These parameter values can be input directly by the user, or can result from fixed equations involving other parameters or even linked spreadsheet values. Using rules in a parametric model allows for conditionally-defined equations. These “conditional equations” are not limited only to the parameters, but can involve all aspects of the design. Equations or relationships can be defined between the parameters, properties, attributes, features, components, or any other aspect of the design. 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. A rules-enriched model is therefore far superior to a simple parametric model.

This iLogic 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.

Subsequent tutorials expand on this information, and show you how to create even more intelligent models, still with only very simple rules.

This tutorial assumes that you are familiar with Inventor 2010, and its basic part modeling functionality and concepts.
