Maintain profile geometry in a loft?

Question asked by Tim González on Jul 18, 2016


I am trying to create a loft with two circles as the start and end profiles and I have them following two splines as the guides. I want the distance between these guide splines to be the diameter of the circular cross section throughout the entire loft. The issue I keep running into is that the cross section won't stay a circle. Instead it will adopt an elliptical shape as the guide splines get closer. I have attached images of what I have now. From the top view, you can see that the loft follows the splines well. However, from the side view you can see that the height of the cross section stays constant which is bad. Hopefully my description isn't too confusing. Please let me know if anyone has a suggestion.
