Walls of decreasing thickness with height

[alahel]

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

Not using just a wall.

This is a 2D Room Molding Polyline (the external room) - which will cut away for doors and windows - but only full height.

It will automatically recognise doors and windows that it passes through and marks them No Molding On Selected Edge.
