I would send you the file, but it is part of your graduate thesis Does this look right?
Your graph was getting close, I think you just thought it was generating incorrectly because you had preview on for both Geometry.Translate and Geometry.Rotate
In either case, there are some unnecessary aspects of your graph - you don’t need to be creating as many ellipses as you were with Geometry.Translate, the lofting will still be smooth with less cross sections and will run more quickly.
Also the Excel file is not necessary for generating the ranges of your Z values for the distance input on Geometry.Translate, and the degrees for Geometry.Rotate. The link that @Thomas_Vogt shared brings you to this tutorial (PDF download): https://onedrive.live.com/?authkey=!ABAke5h1US5JMMk&cid=7EAF8D40A42D53C5&id=7EAF8D40A42D53C5!2763&parId=7EAF8D40A42D53C5!2104&o=OneUp
Since you are creating your ellipse with Ellipse.ByOriginRadii you can skip some of the first pages of that tutorial. The instructions for pages 18 and beyond will get you your results. Post back with progress (like I said, your Dynamo file was giving you close results so you’re nearly there) and I will be happy to give more specific advice !
