Non, c'était bien la première fois. J'ai supprimé les plugins installés dans l'Extension manager et j'ai installé le nouveau lien que tu as posté, fermé SU, réouvert, puis ensuite ré-installé TopoShaper. J'ai réussi à faire un mesh avec les points que j'avais!

Thanks a lot!! Un gros merci @fredo6, ça marche

Hi everyone. I'm came to this community to use the seemingly wonderful TopoShaper but nothing happens on my end... I followed the simple instructions and i get this lines in Ruby :

Error: #<Errno::ENOENT: No such file or directory @ rb_file_s_mtime - /Users/claire/Library/Application Support/.LIBFREDO6_DATA_Dir/LibFredo6_all_defaults.dat>

I'm not code savvy and im new to Point clouds too.
Can anyone offer assistance here?
