Problem with creating a terrain

loft.3dm (8.0 MB)
Hello I have an issue with making the terrain , I have made the height segments and have tried the patch command but its not precise at all and the surface doesn’t stop at the terrain boundaries. I also have tried the loft command but it says ‘Some but not all of the curve end points touch’ to witch i havent find a solution yet .
Thanks a lot in advance!

Hi John - Patch or MeshPatch are going to be the way out here - I’d Join the elevation curves - currently they are grouped. Patch does OK if you leave out the rectangular/outer edge parts:

Needds to be trimmed in Top after the oversized surface is made.
