P PittBull New Member Nov 14, 2019 #1 Having trouble figuring out how to draw parallel 13.5 radius curves. I have the outside curve drawn. I have my center lines spaced at 1.5". Can't get the inside curve drawn to match. What am I missing? Thanks so much. Last edited: Nov 17, 2019

If your outer curve is 13.5" radius and the track spacing is 1.5" then the inner curve needs to have a 12" radius. If you want both curves to be 13.5" radius, then you need to move the center and the curves will not be concentric (parallel for curves.)
