Macro cutCircle/it

Descrizione

Questa macro suddivide un cerchio(i) o arco(i) in archi, gli archi possono essere di colori alternati per distinguerli.

Uso

Copiare la macro cutCirle completa nella console Python di FreeCAD, selezionare il cerchio(i) e/o l'arco(i) poi digitare nella console:

cutCircle(5, 1)  # here with 5 arcs and coloured
cutCircle(4)     # 

per vedere i cerchi e gli archi tagliati, come in questo esempio, in 5 archi contigui.

Gli oggetti originali non vengono eliminati.
