Aotocad 2014- curtain wall transom to be cut on 2 levels .

Hi all,

Attaching the draw.

The top transom (beam) has to be cut on 2 levels degree : in\out as the circle diameter , and up and down as the slope .
I made the drawing with the SWEEP  command  of a 2D transom view along a line, but the result is not good To getthe dimensions ofmanufacturing, it is good as a general "simulation".

How can i do it more accurate?, or it is a big task for the autocad?

Thank you all.

yaron.
