The contributor list states each contributing feature and its percent contribution on the worst case minimum or maximum condition, based on the difference between the measurement nominal value and worst case result.
For example, if the nominal value is 10 mm and the worst case maximum result is 11, the feature contribution is 10% if it consumes 0.1 of the 1 mm tolerance stack.
Below each feature, the list of dimensions and tolerances that cause the contribution are displayed. When you select an item in the list, the dimension or tolerance appears in the graphics area. See Graphics Area Display of TolAnalyst Results. Double-click an item in the list to open the Dimension Tolerance or Change Geometric Tolerance dialog box where you can modify the tolerance values. With these two dialogs, you are editing the part. These are not temporary overrides to values. After modifying tolerance values, click Recalculate to compute new results.
