Grid Pattern on irregular surface

[serabouch]

I want to create a simple grid pattern on an irregular surface:

However, using lunchbox doesn’t fit the grid within the surface boundary:

Is there a way to trim the excess going outside the boundary?:

something like this?

If higher precision is needed, it may be necessary to output it as a grid, trim it, and then reconstruct the surface, which might require scripting. The simplest approach might be to directly export it to Rhino and manually trim it.
