Hi all,

i would like to verify if a connected geometry is closed or not.

Is there a way to do this ?

Thanks

for polygons you can append Divide SOP
check Remove Shared Edges
and if result is empty geometry then the input is closed
otherwise number of faces on output geo means number of holes in your input
