 Knjižnica ukazov za izdelavo zaokrožitev se nahaja v viru BRepFilletAPI in jo je potrebno vključiti v program pred uporabo ukaza:

 Pri apliciranju vseh vrst zaokrožitev je potrebno imeti podatek o robu oziroma točki kamor hočemo izvesti zaokrožitev ter o parametrih zaokrožitve (radij zaokrožitve).

 Pri izdelavi zaokrožitev moramo biti pozorni na velikost zaokrožitve. Vrednost zaokrožitve mora biti dovolj majhna da lahko normalno zaokrožimo robove.
