#2. Then, when filling, roll the middle button of the mouse to enlarge the area to be filled and then select that area.
#3. Then, when filling, fill separately, filling only one area at a time.
4. Then, if it is version 2012 or above, first temporarily hide the objects in the filled area that are not related to the filled boundary, so that the filled area becomes an independent simple area.
#5. Then, after the filling is completed, end the hiding operation of the hidden object.
