Descrizione
Questo strumento 
disegna un cerchio passante per tre punti selezionati dall'utente nella vista 3D. Quando lo strumento è attivo, il puntatore del mouse assume la forma di croce bianca con l'icona arco rosso.
Accanto al puntatore sono visualizzate, in blu, le coordinate della sua posizione, aggiornate in tempo reale.
Utilizzo
See also: Drawing aids.
- 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.
