Hi how do i cull the floor underneath the ground. I was only able to isolate it but I am unable to cull it without the top disappearing.

you need to draw a flat surface that covers your tubes at Z=0. Use “split with surface”, then using the “3D center–point” of each resulting objects, cull those objects whose center point Z < 0. Or simpler, split the tree after the surfsplit and you will have top and bottom objects.

Sorry im on holidays… Cant do it for you. Hope this gets you going.

You could use Shift List to eliminate the bottom curve being passed to the ‘Curves B’ input of the SLOW Region Difference component:

By the way, I eliminated the ‘22’ slider being used for the last Extrude by re-using an earlier slider labeled “Distance Between Each Floor”.

P.S. Looking closer, I see that you ignored the “Distance Between Each Floor” slider at another point in the code and computed a value of 22.5, which leaves a small gap between each extrusion. Is that intentional?
