This may sound involved,but it is not.When you blow up the side view to the scale you want,measure with digital calipers,the part you want .Then,scale the image of the paper cutout sheet to suit the dimension you found on the side view,and print that 1:1 scale.You can pick what dimensional choice you have made on the side view...just be consistent,and follow it through on all your parts(ie,inside the line,middle of the line,outside the line).
