Hello, I have to build a particular mesh . I have built it manually using lines, but now i would like to turn it into an actual mesh to apply it to more complex surfaces. Can you suggest me a solution for this issue ? Thanks in advance [image] myfile.gh (21.2 KB)

This is quite close to an equilateral triangle mesh with midedge subdivision. [image] [image] Deleting the outer loop results in the same topology as on your screenshot. Do you have Weaverbird installed yet? midedge_subdivision.gh (19.5 KB) Alternatively if you want to stick with your approa…

Thanks for the quick response , yes I have weaverbird. The first method works good, but i don’t know how i can control the number of subdivisions/ cells (is there a place where i can attach a number slider?) the second approach seems to not work ( maybe i do something wrong, i attach the file). m…

check the L input you can specify the number of subdivisions. I exploded the curves and increased the maximum face valence to 6. myfile.gh (25.2 KB)

ok the second works good, so i will just continue with my appproach. Thanks.

Martin Siegrist could you help me with this one? I do get this error: [image] Or it works and i only get one face: [image] line to mesh.gh (12.1 KB)

Here’s a way to sort the intersection parameters… [image] [image] line to mesh mrtn.gh (22.2 KB)

That was fast, thank you for your help. I had to change the direction of the lines and now I have two more questions: Why is this one line still displayed after the “Trim Within Region” component, even though the line is outside the region? [image] How do I get rid of these triangular faces…

[image] Thomas: Why is this one line still displayed after the “Trim Within Region” component, even though the line is outside the region? it appears to be coincident. I wouldn’t worrie too much why this happens and instead use a filter to get just the lines which have the start and end point…

FWIW, the native Mesh.CreateFromLines method automatically adds ngons: [2025-05-25 16_43_12-Grasshopper - line to mesh v2_] line to mesh v2_AHD.gh (14.5 KB)

thanks to both of you, im gonne creat a new topic to find a solution
