Lesson II - creating objects using parabole

During the class we have created some objects using parabole and different axis of revolution. 

1. Firstly I have drawn parabole in 2D view.

2. Next step - I used REVSURF command to check how creating shape works. And here is the result.

3. But shape didn't have any thickness so I have created red parabole using OFFSET command and I have linked two paraboles with semi-circumferences and made poliline of them using PEDIT command.

4. Last step it was to create another object using different axis of revolution for the same parabole.
