Drift - At Control Points

The Process > Results > Drift > At Control Points command is available only to rigid diaphragm models.

The Process > Results > Drift > At Control Points allows you to select and store up to four points at which drift will be automatically calculated. This provides a powerful tool for comparing the effects of differing load cases (Analysis Mode) or load combinations (Post-Processing Mode) and designs.

Issuing the Process > Results > Drift > At Control Points command opens the Drift at Control Points dialog. Control points are set from within this dialog box.
