Help with revolve command

Good Day, Please asset me with this problem I am having.
I drew the following lines

Then created a shape using the revolve command

When I remove one of the ends the shape is hollow inside and I need it to be solid.

Please help with making parts created like this solid. I tried the “create solid” command but it doesn’t do anything.

Once the ends are joined to the revolve (use the Join command or use Cap to close the ends of the revolve directly) and it is closed, it IS a solid. In Properties it should read as a closed polysurface. This is the same as a “solid”. There is nothing inside, a solid in any system using BRep (Boundary Representation) such as Rhino is just a closed shell with no holes. Here is some more info on the subject.


Thanks for that, it solved my problem.
