Contour command generates fragmented curves

[Til_Frank]

Hi,

I am having problems creating a contour map of a terrain surface. The surface is very large, about 4000x6000m in size. When I try to create the contours, the curves always come out split with large gaps between them, not connected to each other. See image

I have already tried to create the contours using Grasshopper, also with the Intersect command and cutting planes. As well as splitting the surface into several smaller pieces and also using a lower unit tolerance. I hope someone can help me.

This is typical behavior when contouring complex NURBS surfaces with a lot of points. If you mesh the surface - or use the original DEM point data to create a mesh instead of the surface - and then slice the mesh, you should then get complete curves.

It worked. Thank you very much!
