Sweep on a conical spiral

Hello,
This problem is driving me crazy.
I would simply like to sweep a rectangle along a conical spiral and at the same time rotate it 90°.
If I use the sweep command, I can't control the amount of rotation (it can be 0° if I use lock profile direction, but it is not
what I want) ; if I use the loft command, the dimensions of the rectangle change along the path.
What can i do?
Than you very much
Mario

Have a look into tweep feature by Derek.
@mario_zadra … you need to use Loft…not Sweep.
The trick is to change the point where your Loft Profile intersects the spiral.
1. add a point on the bottom line at the mid-point for both profile sketches.
2. use the pierce constraint from that point to the spiral
