How do I go from sketchup to having a part machined?

I have designed a simple model of a quadcopter frame in the standard sketchup I would like to import into coraldraw so I can have a prototype laser cut out of plywood and then machined out of carbon fiber. How do I go about saving my sketchup model as a dxf file so I can import it into coral draw and then send it out to be machined?

You will need SketchUp Pro for more export formats.

Or if a .STL file format is compatible for you, you can add the stl plugin.
