Hi, When extruding curve to mesh using Rhinocommon(Rhino.Geometry.Mesh.CreateFromCurveExtrusion), it adds one unit on both top and bottom. Please see the post below. [image] Mesh Extrusion not working as expected Grasshopper Developer I’m using the Rhino.Geometry.Mesh.Cr…

[image] woojsung: Tiny gaps might be closed off using the FillHoles method. FillHoles() will fill any holes detected in the mesh regardless of size - they do not even need to be planar, just have naked edges that form one or more continuous loops. Like the native Rhino command. I do not kno…

Yes, you’re right, using FillHoles() is probably going to fix my issues. Although the use of a bbox and vector for that mesh extrusion function are wacky to me, I am willing to jump through those hoops if it means I can use that function.

Hi @devin_jernigan , [image] devin_jernigan: but instead of addressing that issue, you’re giving us relatively slow workarounds I am providing you the solution, not a workaround. Mesh.CreateFromCurveExtrusion is not what you need. Honestly, this probably should not have been exposed in Rhino…

Ok, I understand. I tried to use the script you posted before, but it is doing this. I have tried a bunch of different MeshingParameters settings, but none of them give me what I’m seeing in your file (the simple single quads for each side of the extrusion). Any idea why this is? [image] test_ex…

This should work for you and be very fast, just building a simple mesh directly. Hope it helps! [Screenshot 2022-04-06 220350] ExtrMsh.gh (7.1 KB)

I have found FillHoles() quite slower than CreateFromClosedPolyline(), especially if you already have the Polylines (in this case is just the input and the translation of the input). If you have to find the naked edges then maybe it is different. I think FillHoles() is checking a bunch of other stuf…
