How do I send out a Solidworks surface part to a machining center for machining?

Is the surface sent to the machining center sheet metal? If it is sheet metal, you need to unfold the sheet metal, then put the unfolded drawing inside the drawing, save it as a dwg, then scale it up in CAD, it doesn't matter if the dimensions are labeled or not, it needs to be thick, and it's best to have a frame that shows what you're drawing.
