Analysis Results > Mode Shape prompts you with the following dialog.
It allows you to view a mode shape after a frequency analysis is performed. You need to adjust the mode shape magnification to view the deflected shape properly. Mode shape diagrams are generated for a single mode; multiple mode shapes can be viewed by using multiple view windows. To open a new window, click Settings & Tools > New Window.
Mode Shape diagrams can be created with the ‘shadow’ of the undeformed shape, allowing for more concise presentation of the deflected shape. Like deformation diagrams from static analyses, the Mode Shape diagrams are ‘locked’ so that the model cannot be edited. To edit the model, either remove the diagram or open another window with the undeformed shape displayed.
