Network Surface Failing for these curves, suggestions?

Network Surface seems to be failing for the attached curves. Any suggestions?

Thanks,
Sam

I suggest you rebuild your curves to clean them up and get their point counts the same. Then use sweep 2 rails. Even if don’t rebuild the curves you will get a more accurate surface with sweep 2.

That worked, thanks Stratosfear,
