The direction of the resulting surface


#1

The resulting surface may have an incorrect direction (for example, inside, but it needs to be inside), the direction depends on how I choose the curves or edges (the selection sequence). How to choose, so that the final surface has the right direction?


#2

It also depends on the direction of the curves the surface is being made from - and perhaps some other factors. So the short answer is - you can’t always predict which way the normal side will fall. Best is to make a display mode that shows backfaces as a different color, then when you see some surfaces are reversed from what you would like, select their original generating curves and call Flip - if you want history to transfer, or just flip the surface(s) - history will be broken.

And sure to be in any way? :frowning_face:
