Hi Gunter,

> I made sure the last point on the left was not in line just as the tutorial specified but it still doesn't work.

Can you please post the 3DM model file with your specific curve in it so I can take a look at what you've got?

One other note - you will also probably want to uncheck the "Cap ends" revolve option (when you're in Revolve look in the upper-right area of the main window for the options for the current running command), so that it doesn't also add an additional planar end cap to try and seal off the end to make a solid.
