Here a multiple variable Fillets on a same edge! :)
One general with 3 unities angle
Two with 2 unities angle
One with 0 unity angle

When you press the last "Done" edition will be not possible : only CTRL + Z but all will be losted!



Remark that previous fillets will be not visible when you add news point!
So draw Lines Guid for some help! They stay between new adds till the last "Done"! ;)
