Hi, with reference to this image:
The five steps you did above are nice ones. I think there should be one more step before the last step (ambiguous)?!!!
I have tried many times with small and larges scales, to use Alt-Move with irregular objects, but always the model got distorted. Is the auto-fold used only with regular objects only? as it has equal distances from the far edge?
I can see clearly you used Alt-Move (auto fold) with irregular object and works fine. Please explain it to me very well as I searched the internet and the community forum but always they talk about regular shapes such as square, circle, polygon, etc…
In the red area (No.1) there was no straight line beside the curve but when I auto fold it a line separated the curve and the original edge (non smooth auto fold). Also, in the red area (No. 2), was not considered in the geometry when auto folded. Every thing is available for you, please investigate and provide your valuable comments and tips.

Many thanks Gully for your prompt support.
