Descrizione
Disegna un arco dalla selezione di tre punti: il centro, l'angolo iniziale lungo (contemporaneamente) il raggio, e l'angolo finale.
Quando si avvia lo strumento, il puntatore del mouse assume la forma di croce bianca accompagnata dall'icona rossa di un arco. Accanto al puntatore sono visualizzate, in blu, le coordinate della sua posizione aggiornate in tempo reale.
Utilizzo
- Selezionare i punti su un'area vuota della vista 3D, o su un oggetto esistente. I vincoli automatici (auto constraints) si attivano nella scheda Azioni → Modifica controlli → Autovincoli del pannello Vista combinata.
- Premere il tasto Esc, o cliccare sul tasto destro del mouse, per annullare l'operazione.
