Dear Mr Gibson,

The Revolved command has a strange behavior. As you can see on the image, I am using a closed profile to obtain it hollow from inside.

Could you please take a look at this save file that I am sending with my question to see why I am experiencing this issue. I'd appreciate it if you could send me the working Revolved command as well.

Before, I never noticed anything wrong, but now something goes wrong and I'm curious to know what's causing it.

THANK YOU IN ADVANCE.
