Geometry.Intersect not work well

I used the geometry intersect with plans, and the result as you can see from the second picture. I just got half of the surface. I don’t know what’s wrong.

post your graph and/ or your files pls…

ExcelPoints.dyn (33.1 KB)
point.xls (49.5 KB)

your “workspace of geometry” is to low…set it to the highst…

…picture in german…

or just reduce the points from 100000 to 1000

Thank you very much.

pls mark my post as solution:)
