need help creating 3d logo

so I have used bevier curves to make the shape and joined it together makin it one face. Now I know how to extrude it to make it 3d but then how do I select the individual faces to set material textures on(like I can easily do with the default cube). I have the logo in 3d form but can only click and edit the bezier curves. Do I need to convert it to a 3d object somehow?

Using curves you only have one face between 2 curves. You can select all the control points of two curves that make one face and hit P to seperate it, then give it a different material.

Or perhaps use Alt C to convert it to a mesh, then you can assign different materials to different parts… different colored front, sides and back faces. You can’t do that with curves.
