Well, you could draw a scale in SketchUp, send to LayOut and make it Ortho with a scale (I chose 1" = 1', but this can be changed), vector render the model, add text labels in LayOut, and save as a Scrapbook called Scales.layout. That's what I did.
Of course, you can create a prettier scale drawing, pick a better font, etc..
