Hi,

I have a bent polygon that I want to transform into a very light and simple, yet exact, surface.

Patch does it, but not at all exact, as expected: the patch surface does NOT touch the curve perfectly.
I have tried adding a curve from the centre to sweep which rendered no result.

Attached is a file with:

  • a deformed polygon (pentagon)
  • the same polygon, mapped on a double-curved surface
  • the goal (made by cutting the lower part of a sphere, yet this is not an option)

Any suggestions very, very welcome!

Best regards,

Why don’t you explain why cutting a sphere is not an option?

Because I want to use Map to surface later!

SrfMorph is, according to me, to inaccurate but surely to heavy.

(Yes, ok I could do flow along surface in Rhino…)

So, creating surfaces after a multiplication of their construction curves is a faster sketch method.

Is that a good answer for you?
:wink:
