Hello All,
I was looking at the Excel program for making cat cut tarps and I had an idea and thought I would send it out to see if anyone has done this. The program gives you a list of x and y coordinates used to transfer the shape of the cut. It also gives a sag dimension that shows what I think is the deepest part of the cut at the center of the dimension "a". Instead of marking all these coordinates and connecting them, what if you took a piece of wood, 1/4" x 3/4" maybe pine or cedar, and held them at the corners and then found the center and raised it to the "sag" dimension and traced the line onto the pattern? You would get a fair curve and it would only take seconds to lay it out. You might need a little help holding the ends down but would this give a true cat cut? Would it work and has anyone tried this?
