Descrizione
Questa macro crea una vite oppure un bullone, con o senza la filettatura, secondo le norme ISO.



Utilizzo
Selezionare le caratteristiche della vite e fare clic sul pulsante Crea

Se si seleziona un cerchio di un foro, o in alternativa la superficie interna di uno scavo circolare e contemporaneamente il cerchio superiore di questo scavo, la vite viene creata dentro lo scavo.
