Merge two solids

[Jabba]

First time in any cad software so this might be an easy one. I have created a bangle type shape out of two sketches. I used an ellipse and a sketch, then I used 'revolve a wire face. They are treated as separate parts, how do I merge them into one? I am going to send the file to China for rapid prototyping, not sure how it work out not joind together. 

Thx.
