Wasting the contractor three trips, and wrecking my finances in the process.
You'll want to navigate to the other Figure and do the drafting. Once you've created the image, you can do the overlay, and compare.

But they won't claim that adding something to the roof will change the thermal insulation 37%, when really they get that number by doing far more things than just the roof.
Do the overlay? Is there a template(s) for the front now? Because that is where the golf got most of its drag reduction from.
