Needed help with surface

Hi I’m trying to create a shoe that I’m gonna 3D print later. I’m trying to make surfaces from curves using curve network but It’s not creating what I had in mind. It’s creating this mangled shape that curves inwards. I’m wondering if I should add some more curves, change the existing ones or do some repairing later.

Could you share a skech or a rendering of what you originally had in mind? Also, could you share your current .3dm file? Thank you.

It might be easier to create this with a larger surface in the area, then use trims and/or wire cuts to separate the surface that you want to keep. Perhaps that is not your design intent, and there is a reason you would not choose to model it that way.

Thanks a lot but I decided to do curve network in smaller sections and it worked!

that is most likely the worst solution. if you ever decide to learn rhino a bit better share a file.
