Reply to "Easement: Curves from tangent?"

So I am going to take a shot at this. MELGAR, correct me if needed please, as I am not 100% on this.  The spiral curve is always changing, growing or shrinking, it never straightens out, even at the very end. It wraps into itself. If you were to splice into the spiral, Or follow a tangent line from the curve....that makes it an easement.  Look at the tangent line graph in MELGAR graph. Hopefully, I put out a good explanation, please tell me if I did not.  Think of the spiral like a ‘French curve” that connects two straights.
