This seems like a simple one, or is it working “as expected”? I am using a 3d polyline to create points, this a long and narrow survey pickup a bit like a foot path or slab. I am using the Delaunay by points but if draws all the connecting lines, so for 37 points I get 1800+ lines. I have tried changing the lacing but that just fails for everything except Auto.
The reason I just didn’t want to use a TIN was I want to be able to do it over a number or elements creating a solid based on the value attached to the string.
Building the solid was no issue but the top and bottom surface are a poor representation of the data (to much curve). Any suggestions re setting or other solutions would be fantastic.
Thanks

I believe that is working as expected. My understanding of the Delaunay nodes is that they are for creating the triangulation of provided points. If you’re after a smaller subset of these lines, you’ll need to filter them out - possibly using your original polyline as a centerline of a swath boundary or use a “distance to” type of check.
Hard to say with the data given, but this does look right as far as the structure goes. That said you likely want to use a 2D Delaunay of the 3D points or you’ll get some unwanted triangles underneath/at the sides.
From a pure performance perspective it may also be that you are better off patching to a surface and triangulating that via Dynamo’s tessellation tools which are primarily used for the geometry display. But if you’re not working with real surfaces, you can also just take the surface as is and work with that.
