AutoCAD Inventor :: Switch From SolidWorks To ILogic And IPart

We are looking to switch from SW to Autodesk in order to utilize advanced surfacing in Alias, and its interoperability with Inventor.  However, we need to continue to perform Kinimatic linkage studies as well using Inventor.  I need to make sure we can perform the same calculations with ease before making the switch.

At this point I am trying to mimic in Inventor the kinimatic studies I perform in SW.  In SW I would perform these studies within a single part file, using a single sketch only (no solid parts).  Within this part file I would break up the total "travel" of the linkage into configurations that are driven by a "Design Table".  The Design Table would be used for both the main driving value, and for any driven values I wanted to use for analysis.

I am trying to find a way to get the same driven variables written to an Excel file to use for analysis using Inventor.

As a test example:

I would like to drive one variable(Damper Length) to get ~20 different iParts, each with the linkage moved to a new point within its set range of motion.  I then would like to write several Driven variables(Displacement_1-3 shown in "RULE CODE" attachement) from each iPart instance to an Excel file.

I have been able to get my 20 iParts and the linkage to move accordingly(iPART INSTANCES attachement), but I have not figured out how to write the driven data to excel for each iPart instance(20 rows of data, 3 columns).  I have only been able to write the dimesions for one row of data...whichever iPart is currently open.

with the necessary iLogic code or another solution?  It seems like this should be pretty straight forward.  Do I need to be using the "ChangeRow" iPart Snippet?
