Yes it does need to be a smooth transition. I am using V18 and I don't see a variable blend option. I am assuming that the solution lies in the Face Blend menu.
I need some assistance on creating a compound blend on the root fillet of a blade. I thought it may be in the Face Blend command but I could not get it to work. I need to have 2 different Radii on the leading edge and trailing edge and 2 different radii on the suction side and pressure side.
