Se pueden agregar o insertar bucles en los contornos del sombreado. Los sombreados asociativos se actualizan para igualarse a los cambios efectuados en sus contornos. Los sombreados no asociativos no se actualizan.
Para editar un contorno de sombreado, utilice uno de los métodos siguientes:
Adición de un bucle interior a un sombreado.
Este ejemplo crea un sombreado asociativo. Después crea un círculo y lo añade como bucle interno del sombreado.
