Thanks Rich, I checked out LazyTurn, but I think that Dolphin has everything we need and isn't outrageous in price. The finished profile is in fact standard for solid wheels, however it is the uncut profile that changes with each used wheel. This depending on wear time before removal, train speed, type of terrain, is it a freight car, was it on a 2 or three axle truck on a locomotive, was it flat spotted, etc. Now, I just need to decide how I can quickly digitize the uncut profile of the used railway wheel and turn it into a spline in a DXF.
