Compare UniScan and MultiScan Measurements

UniScan Measurements

UniScan measurements take one group of evenly 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.

MultiScan Measurements

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 it is often the case that MultiScan is the only way to solve for a centerline. (UniScan would reject those kinds of straights with the normal tolerances.)

MTA Measurements

MTA (Measured Tube Averaging), combined with UniScan measuring, is the the best type of measuring available in VTube-LASER. MTA allows you to measure multiple sides of the same tube, then average the results into a single final tube shape.
