Suggestions on how to make a clean surface out of these curves

Hello everyone!

I have these construction curves that I need to use to make a clean surface, in the end it should look like these one:

the issue is that whenever I try to sweep for exemple a part of the arch or the whole arch itself along the top curve, I will always have some parts that are not intersecting and so on. Do you know if there is any other way around this? I tried already the sweep1 and sweep2 also the loft but nothing seems to work out for now…..

if you could post your file that would be helpful for someone to take a look :+1:

Hi Leo,

I rebuilt your curves and then created the organic form using a Network Surface, which I trimmed afterward. The issue comes from having two separate lines instead of one continuous curve — Rhino will split the surface at the join. To fix this, you can either Rebuild the curve or redraw it using the Interpolate Curve command.

Hi Jesse,

Thank you for your solution that also works out, I think I have managed in the end with a simple loft between the arches.
