Buonasera, vorrei unire due liste di circonferenze in modo controllato per generare con un solo comando sweep tutte le superfici che desidero, in allegato le foto ed il file gh,

Mi scuso se la domanda risulta banale o già discussa ma purtroppo sto approcciando da poco al software e non riesco neanche ad estrarre un singolo valore dalla lista.

Grazie mille cordiali saluti

Graft, in pratica divide una lista in tante liste da un elemento.  
Poi, come vedi, si possono riunire, in diverse liste, gli elementi che hanno lo stesso indice.  
Non è una spiegazione molto tecnica ma spero sia chiaro il concetto.
