    I just seen your video on you tube on Horizontal Alignment for Arc – Spiral – Arc InRoads V8i (SELECTseries). I’m trying to do a Spiral Curve and I went through all your steps. My question is, when I review my curve data, there is no “P.I.” on my Circular Element. I have both “S.P.I.” on the Spiral Curve Spiral. I hope this gets to you and also make sense.
