Hi Greg, With a single turn primary, the top and bottom heights can be equal as long as the single loop is given a radius of r2 larger than r1. I had to find some way to prevent impossible dimensions from running. When this happens, geotc will cause a bailout, thus, I was writing validation for every "possible" configuration. I ran into this very situation with single turn loops, where we would want to make r1=r2, but this causes problems elsewhere if h1=h2 at the same time. In order to run the single turn loop, I wrote the validation to prevent an r1=r2 if h1=h2 situation. Thus, to run the single turn loop, make r2 slightly larger than r1. Check the single turn loop demo. There you'll find r1 = .5, r2 = .500001, h1 = 0, h2 = 0. That's the way to do this at this time. I'll look into seeing what I can do with the validation to allow this and still prevent bad inputs from getting into geotc. I figured this would come up and glad it did. It just confirms that I need to spend more time in that area.
