I would like to make a rounded surface that follows two guide curves but I can't find an adequate function... Indeed, when I use a sweep, my section is respected but my surface follows only one of the two curves. So I tested with a smoothing or the boundary surface tool by adding sections but it gives me a not very satisfactory result because as you can see on the photo it is not continuous.
Do you have a tip, a tip to make a beautiful continuous surface?
