Wow π² Rich & Marian I'am blown away by these brilliant interpretations. So, Rich I downloaded Fredo's Curviloft and did just what you said, viola! That is soooo smooth and pretty simple to understand the way in which you can achieve this through the drawing of the connected curves. You're right, after this just spend a little time and round it up a bit.
Marian, nicely done as well. Your process ended up pretty smooth and not leaving a whole lot to fine tune. I guess it depends on how critical and precise one wants to get. I will now take some time to attempt your process and get back.
Awesome, thanks a million π
