The View/Update command lets you pick a particular member and view the different components of its participation factor (such as flexural, shear, joint and axial). For example doing a view/update on a beam will display the beam properties (size, Fy etc) and also its axial, joint, shear and flexural displacement participation factors that contribute to the total drift of the building.

You can also modify the member size and material properties in this dialog box. Once sizes and material properties are changed, the Drift-Control Module automatically recalculates the member PFs based on the new data. However, note that, the elastic stiffness analysis results still remain the same until a re-analysis is invoked from the Analysis mode.
