Deleting diagonal line from surface

image

Hello,

I try to get a surface between these grid points. The diagonal lines have to be removed. Does anyone know how to remove these? if that does not work i want to do it without mesh.

Looks like a mesh instead of a NURBS surface. Way, WAY too complex :bangbang:

P.S. I don’t know why your code is so complex? It appears you are exporting data to XML at the end? But the initial geometry can be this simple:

Thanks for helping me out. I’m a beginner with Grasshopper that’s why i can’t find all the components and try to do it in other ways. The complexity is done because i have to be able to change the coordinates by a mathematical formula, so that the coordinates change parametric with the formula.
And you’re right i’m making an XML-file at the end.

ps. with the ‘surface split’ component i get the points where the surfaces intersect. Is there an easy way to separate the center points from the edge points in separate lists?

Probably yes but I don’t know know what you are trying to do.

sorry for the confusion.
I’m creating a point supported floor that can be transported with an XML file to SCIA Engineer (construction calculation software).
The points have to be supported by supports, so i try to get the coordinates from the intersection points of the horizontal lines and vertical lines. To these coordinates i will connect the supports.

But the intersection points on the 4 edges of the surface need to have different supports than the coordinates in the middle part. That’s why i need the intersection points on the edges (blue) as a separate list and the intersection points in the middle (green) as as separate list.

Use the Value List (blue group) to choose which list of points is labeled.

P.S. You can rearrange components to put Sort Points before Dispatch, like this:
