Pick your most + point, and your most - point, plus the start point and end points, and apply that correction to those 4 points only using lincurve & offset. Measure it again. How much error is there now? And where? Pick the next pair of maximum errors, and where you are inserting between previous points, slide the higher points one x#y# pigeon hole up to make room for the in-between point. Pretty soon you'll be trying to compensate for the room temp variations, and I doubt you would need more than 10 of the 16 settings the default build of the module provides. Actually, if I was doing it, I think I'd start at zero, move up the rails until you hit the first thousandth error. Set lincurves x1 and y1. Measure to the next place you find a thou error, set x2y2 to fix that. Repeat till you are at the other end of the rails. and I doubt you would need more than 10 of the correction points you have. And in any stretch of the rails where you seem to be fixing a straight line where the xN and xn+2 passes thru the point between them, the one in the middle can be deleted by putting the x4y4 values into the x3y3 box. > ----------------------------------------------------------------------- > ------- Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT > Server from Actuate!
