Is there a way to call 3D convex hull from C# code?

You could also implement MIConvexHull directly, which is what MeshEdit implements I believe. Here’s a GHPython example, should be simple to port to C#:

VB to Python

It’d help with debugging if you also upload a Grasshopper file that demonstrates the error. On a sidenote, I’d highly recommend implementing MIConvexHull for computing fast, clean and stable 2D/3D convex hulls. I’ve been using that on several projects recently (including this one), where the standard Grasshopper convex hull solver would fail. Here’s a quick example that should work if you unzip the MIConvexHull.dll to the default Grasshopper libraries folder: [2022-03-25 10_15_16-] 230425_Co…
