In this case you can use Surface Split:

Hi Marthin, thanks for your time! Yes. I was trying with surface split actually.

But I was also trying with the shatter component, to have more control of the line direction.

Do you have any idea?

Thank you!!

Without Pufferfish, I did not understand your objective until I looked at @martinsiegrist’s code, then did something different. I moved the LINHA CALÇADA in the direction and twice the distance between nearest corner points, intersected the moved curve with LINHA LOTE, shattered both and joined the correct fragments.

Curves are internalized, no need for Rhino file.
