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.

The Y dimension will be 13, since it is already dimensioned the way VTube-LASER will dimension a part.

Set the Datum

It's necessary to set the datum using the Datum tab in the MASTER DATA menu.

It may also be necessary to rotate the master tube into the an orientation that is similar to the print. In this case, we used the Transform feature to rotate the master tube so that the first leg is vertical.

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.
