about the curves warning.

the g output tree has many nulls (due to different building heights), hence the warning in boundary component. try using a clean tree component and the warning will go away. the boundary geometry seem ok. also try working closer to world 0,0,0 origin.

about the normal. seems that boundary component outputs some surfaces flipped. don't why exactly. here is a way to flip them. for some strange reason these dont get flipped unless there is a merge faces component.

best

Dear Alex, thank you very much for the suggestions from which I learned a lot:

1. the "clear tree" component

2. the functions of "sift" and "combine data"

It seems that the list feeding into the sift component needs to be flattened to produce the right results. Hope you can kindly confirm.

Thanks!
