I am trying to make a ring. Please see the attachment for the results.

Looking from the 0.0.0 to the right
The first sweep
I cannot filet all the sharp corners.
Rails were rounded sides
The scaling rail - both the straight sides (joined)

The second
After the sweep there is something in the bottom.
Rails were rounded sides
The scaling rail - one of the straight sides

The third
After the sweep there is something in the bottom (some sprit).
Rails were straight sides
The scaling rail - one of the rounded sides

I am confused. Can you help me please.

Regards
Olga
