Using a Datum to Get Print Dimensions

How to Use Datums To Get Print Dimensions

Sample Print

This is a sample print with the design intent of checking the width and the height. You can use the VTube-LASER DATUM feature to get to these dimensions. The diameter of this part is 1.25 inches. You will need to find the X centerline dimension by subtracting 1.25 from 5.5. So - the X dimension should be 5.5 - 1.25 = 4.25.

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.
