Curvature intersection method

A couple of pictures showing one method of to help determine how to cut a panel to match up with the complex curves on the side of a car. This is basically the intersection of a plane and the side of the car so as to minimize the bending of the applied panel. I used a cheap Black and Decker laser gimmick that projects a laser line as shown in the pictures.




I had already done the front by the time I thought about this and it won't work there now so I projected behind the front wheel well (same curvature) to see if it looked like what I already did, looks pretty close to me.
