Patch Surface Problem

I have got 5 curves from 1 exploded curve. But I can’t create surface from these curves. I used the Patch command. But Patched surface, it doesn’t fit the real curves exactly. There are some screenshots from my curves and surface. What should I do?



Hello- hard corners will seldom match exactly unless they are planar - the patch surface cannot have a kink in it, it must be smooth.
Please post a file with the curves, I’ll try to suggest an alternative approach.

Thanks for answering. Here are the curves and I got a one more question. Is there a different command to make surface from these curves?

Hello- try as two surfaces:
