G. Afternoon,

I’m trying to recreate the building in the image. Starting from the plain surface i run the comand and get quite a messy result, its like the two things do not match even though they should.

does anymody have an idea? on how to achieve this?

Ciao Francesco, benvenuto.  
Le superfici in piano come le hai ricavate?

mi sono state fornite, a dire la verità ho piu o meno capito perche non andava anche se la soluzione è un po rudimentale. dovevo stare più attento ad i parametri e punti di selezione del comando

Il comando, con le nuove versioni di Rhino, in effetti è diventato più “delicato”.  
Comunque ho provato a ricreare al volo le superfici piane con i comandi \_Unroll o \_Smash, e mi pare vengano parecchio differenti dalle superfici che stai usando.  
Con quelle che ho creato io, il comando \_FlowAlongSrf funziona correttamente.
