1. Generate the outside footprint of the Stadium by using the superellipse script.

2. Generate an inner drip line also using the superellipse script.

3. Set an structural grid and join the outside footprint with the inner drip line with bays.

4. Relate the file to an existing Rhino file that contains a control curve and divide the curves in the the same number of bays.

5. Generate profile curves that respond to the control curve and also using the superellipse script changin the plane in which the curve is generated.

6. Offset the profile curves and loft them generating the Aviva type volume.
