Hi, I am new so be patient with me.

Il perché non funzioni non lo so, però io la risolvo così.

Benissimo Giuseppe, mi ha fatto molto piacere sentirti.

Scusa se mi sono rivolto al forum e non a te, ma è stato solo per non disturbarti.

Con l’anno nuovo mi riprometto di venirti a “scocciare” per le ultime novità di Rhino 8 e perché ti devo parlare.

Per ora ti auguro buon Natale e buon inizio d’anno. A presto, Leo.

Ma figurati che disturbo è invece un piacere sentirti!!!  
Contento vada tutto bene. Ti aspetto con piacere. Manda un messaggio prima così sono sicuro di esserci.

Avviata la definizione su Rh8 e creata una Brep simile non ho quegli zeri ma valori congruenti.  
Il fine della definizione è ottenere le curve di bordo della faccia superiore e inferiore?

Si, esattamente, mi servivano le sue curve di bordo.

Comunque ne parleremo quando sarà, perché ho un bel po’ di dubbi.

Grazie sempre di tutto Giuseppe.
