Cut Holes on Non Planar Surface

Hi there.

I'm designing a fence which has 2 elements.

1) Fence posts,

2) Fence screen.

Fence posts are sorted. i need help with fence screen. Fence screen consists for 12mm timber ply sheet with holes punched in it.

I have created a surface and projected curves (circle) on the screen and have also solved the intersection between surface and curves.

However, i need to use these circles to cut holes on the surface, but I'am not able to achieve it. I have used 'split surface' component, but it aint doing the job.

Can any-1 please help? - attached is my definition along with rhino file.

Regards,

Hi Agneesh,

Check the attached file.

Btw, I lowered the number of "populate 2d" component points (from 85 to 15) due to poor performance of my PC. You can get it back if you wish.

It works, thank you so much. Could you please explain me split-surface? i saw you have reversed the list?

kind regards,

Agneesh

"Split surface" will just cut/drill the initial surface with the supplied curves. As a result you will get the drilled pieces too. So what you need is to "select" only the drilled surface, without those pieces. In this case that was the last item.You can "get" that last item by using the "List Item", with index 0, and by reversing the list. The other way would be not to reverse the list, but simply to assign the index of the last item in the list.

By the way, I am not sure by which criteria the drilled surface index is determined. Sometimes it is the last item in the "Split surface" resulting list, sometimes it is the first, or even somewhere in between.
