Surface From Points - question

(I want to post this to FAQ but couldn't find it from the category drop-down menu...)

Hi All,

I want to build a surface from a series of points by using Surface From Points, however, the result turns out as the attached images.
I've already flattened the points input and also put U+1 for the U Count expression.

I wonder how to fix it so that the outcome surface can wrap around nice and clean?

Thanks a lot!

Sorry for the quick update...

Lately, I figured that the reason why it wraps crazily is because the points are not in order. After flipping the surface around it looks much better.

Now, is there a way to close the gap between start and end?
Although I can always split the surface and mirror the good side, just wonder if its possible to make a closed continued surface in one shot.

If you want to make closed surface, then you should repeat first point grid branch at the end.
