Creating surface from points issue

i can’t create a surface from points in grasshopper; I have only succeeded to create a mesh surface
i am new in grasshopper help me pleaseeeeeee

you should send Gh file. (4.1 MB)
Thank you in advance

if you set a Curve that is a bit smaller than your mesh, then it works well:

that happens because the Delaunay mesh that is created is a bit smaller than the bounding box of the mesh itself, see the trimmed corner for instance

so when mesh rays are shoot they don’t intersect anything, like in this case, and the Surface from Points gets Nulls which make it fail


It worked …Thank you so much
