The way to fix wavy loft surface

Rhino
1

Hello again, this piece is a civil aircraft engine pylon, I have the shape created by polysurface (1), because I am going to add mass details on it and some detail is positioned on the joined surface edges which will cause troubles when client ask me to modify, so I recreate 1 piece of clean surface by rebuilding the section curves (2) and lofted the surface with loose option (3) Maybe due to the distorted geometry, there is some wavy area, I tried smooth command and it will deform the whole piece of surface. I also try to select the edit points in related area but it will leave a mark at the surrounding of selected points.
So my question is how to control better the smooth fucntion, or alternative way to fix this wavy area. thanks.

Reduce the number of profile curves and maybe try the loose option…

Thanks for suggestion. Here is the result of loft surface with reduced profile curves with loose option. What do you think?


I use windows btn+G to record the video, the pop up of loft is not recorded.

Ok, better in one direction and for the other direction you need to rebuild the profiles.

Thank you and yes I think the other shape direction need to be control as well. I will try when I get back to work. :+1:
