Diamond Grid - Boundary

[Jin_Tae_Kim]

Hi all. Happy Humpday, I hope everyone is doing well.
Today I have a question about how to contain the diamond grid that I created using Lunchbox.
I can’t seem to figure out how to contain within the region of the boundary.

I have a surface and I would like to create the boundary within the boundary of the surface.
Any help would be greatly appreciated.

Thank you,

The reason it is because you are working with trimmed surface. You can either project the geometry back onto the orginal surface or use surface morph.

Also please upload your file, so people can help you.
