UniScan measurements take one group of evening spaced points over the entire straight. The method use to measure with UniScan is like spray painting.

UniScan is the best way to get to a true centerline average - especially for deformed diameters in straights. The reason is because UniScan averages out the entire surface of the straight measured.

MulitScan only measures near the tangents of a straight. (The tangents are the locations on the straights where the straights and bends meet.

MultiScan measurements are usually reserved for straights that are bowed - like in brake lines with long straights.

For those kinds of tubes
  • Then measure that part of the tube to learn the clocking to the previous bend angle.

  • You can use the VIEW TRANSFORM control to reorient the new master tube so that the view is looking down the appropriate straight.
