Ceiling Panels with Attractor

I am trying to build a triangular ceiling grid and extrusion based on a point attractor. I have succeeded with a simple extrusion, however, when I add an offest modifier it fails. Any hint where there could be the problem?

I have now included a flatten “command” to the output. It might now work - but I do not really understand why. Might need some tutorials for data trees I guess.

“Graft” also works here. Mind the path matching. If you use Offset Curve, it will add the branch path index one more at the end…so I use Shift Pathsafter that.
