Hi, thanks for the response. I don't believe that it's intentionally out of square (I can't confirm currently).
I would love to see a video of how you would reproduce the part in that I'd learn a great deal from it so I do greatly appreciate the offer.

I also still would like to learn how to address issues in an existing model so I look forward to more responses.

(A meta question, is anyone interested in providing for a modest fee some 1:1 MOI tutoring perhaps via screen share?--I love the simplicity of the UI of MOI but just still having a problem getting to the aha! moment with NURBS modeling)
