Assembly Runout TSU Exercise

When the part is rotated about datum axis A 180 degrees, the indicator max movement would be twice the eccentricity. The axis of the features could also have been displaced an amount equal to twice the eccentricity. Therefore, for purposes of tolerance analysis, a circular or total runout tolerance may be treated as though a positional tolerance modified RFS had been specified.

-The method for calculating assembly TSU using circular runout, total runout and concentricity tolerance is the same as for the part TSU
