Newb Question Creating a Solid

I'm basically a newb at this and this is my first time using solidworks. This may be a very simple thing to do.

So basically i build out an object which is composed different features such as Extruded Boss/Base, Extruded Cuts etc. i dont see the part as a single solid body, but made up the seperate extrude boss/base and extruded cuts...

Is there a way to turn the features into a single solid body or is that not needed if i'm going to CAM with this?

Thanks,

Taha
