There are good tutorials for how to turn a full-size plan into a colored skin for your airplane, but my problem is I live in a place where the available foam is 5mm rather than 4mm. It already doesn't have any paper on it, so I want to print full size plans to use as the skin of the airplane, but the difference in foam thickness causes a huge number of misalignments. So again I'm wondering, to actually modify the dimensions of the plan itself, how would you tackle this problem? Scaling, by the way, is not an option, because I don't want a final plane that's 20% larger than the original.
