Hello, is it possible in CA to have a wall with changing thickness? i.e. a bottom wide thickness and a narrower top one, varying smoothly with elevation? I was not able to find a "proper" way; I am currently modeling with a wall of the minor thickness and a cad block faking the sloping part. I was also thinking about 3d molding but I am not sure if it is the best way. Any ideas? Thanks, - Alessandro
