Data conversion failed from Curve to Brep

Hi every one,

I’ve been trying to create an uniform grid on a surface but I have ran into this error that the “Data conversion failed from Curve to Brep”. Does anybody know how can I fix it?
Thanks in advanced.

The component you are using expects the ‘C’ (Cutting Shape) input to be another brep, not a curve.
