Control point issue

I’m having issues with the points on command. It seems whenever I use this on a rebuilt surface and try to move one of the points, it makes the surface pointy instead of smooth and rounded!Any idea how to fix this?

Seems your surface is Degree 1 in U and V, Rebuild it to atleast deg 3

When you run the Rebuild command, increase the Degree to 3, then the spiky surface will form smoother curvature (rule o thumb, U & V shouldalways have values of at least Degree + 1):

HA thank you so much. I’ve been using grasshopper for so long, the rebuild command on Rhino felt foreign to me. Thanks again!
