The deflected shape is really helpful to understanding your model’s behavior.
You can view the deflected shape of your model in RISAFloor. Just change the view to the Isometric view and click on the Deflected Shape Icon. (Note: If you don’t have Deflected Shape Icon, you can add it to your customized toolbar).
You can also fine-tune the Deflection settings by opening the Plot Options dialog and clicking on the Deflection tab. You can select the magnification factor and Load Combination to show deflected.
