Steps 1 thru 15.

1. Step 1:

   1. Create the circle on the yz-plane. Exit sketcher. Be sure to name your sketches, otherwise it's difficult to keep track of everything.
   

   

2. Step 2:

   2. Enter sketcher on the yz-plane and create the spline shown. Exit sketcher.
   

   

3. Step 3:

   3. Create the following spline on the yz-plane. Exit sketcher.
   

   

4. Step 4:

   4. Create the following spline on the zx-plane. Exit sketcher.
   

   

5. Step 5:

   5. Create the following spline on the zx-plane. Exit sketcher.
   

   

6. Step 6:

   6. Extrude the first spline.
   

   

7. Step 7:

   7. Extrude the 2nd spline.
   

   

8. Step 8:

   8. and the 3rd...
   

   

9. Step 9:

   9. and the 4th... You should end up with a kind-of box.
   

   

10. Step 10:

    10. Create an intersection curve as shown.
    

    

11. Step 11:

    11. Create another intersection curve.
    

    

12. Step 12:

    12. Create the plane as shown.
    

    

13. Step 13:

    13. Create 2 intersection points. Click the button shown to add the 2 curves.
    

    

14. Step 14:

    14. Enter sketcher on the plane you just made and make the following shape. The two endpoints should be coincident with the two intersection points you just made.
    

    

15. Step 15:

    15. Make another plane as shown.
