I couldn't retrieve surfaces ( boundary surfaces and others not working )

Hi all ! i used parakeet and shaper3d for the pattern, the output of the visual script is a set of curves , after that nothing is working in order to retrieve surfaces from closed regions , " network regions" from parakeet , “geometric region” from Heteroptera , “boundary surfaces” from native grasshopper… i would be very thankful for any help .


data internalized :
boundary surface issue.gh (107.5 KB)

Isn’t region 2D?

before fitting to surface, yes it is 2D .

Anyone ?
