Interpolate curve

Heyy everyone, im still a newbie to ghp as I was trying to create a surface out of a list of interpolated curves. I started putting some 2D points on my base and I extruded them in Z so I could use them as a guide for my surface. Then I interpolated the curve to create some movement on the lower part and I wanted to create a loft out of the curves simulating the tower skin, but I cant get my loft to just use the exterior curves and not the ones that I created on the inside, could somebody help me please? Thanks!!

I’m not really sure I have understood what you would like to do here…
you can use a flip matrix to get these curves? lofting them won’t make you happy tho… :slight_smile:
