Square-Grid on planar surface

Hi everyone,

I am novice in Grasshopper and so I joined this forum.

I wanted to create a square grid on a variable surface, as shown on the pic:

As you can see, the subsurfaces touches the boundaries were not generated. Anybody knows why?

Thanks

Projection doesn't work the way you seem to expect. See comments in the GH file.

Thanks so far! Didn't know that "project" produces open curves at the edges. The further step to close these open curves is replicable, but why is returning of the overlapping region of boundary and edge suqares such a heavy operation? Just for a better understanding.

Is it now possible to pick one subsurface to measure the distance for example to a point. I want to do this for each subsurface.

RInt is just a component that takes a lot of time to solve. I don't know why.

All the interior squares will come out unchanged anyway so there is no need to calcualte RInt for them.

Easyiest way to calculate the distances is to get the surface centroid (surface area component) then measure point to point distance for each subsurface.
