# Mode Shape

How to view a deflected mode shape after a frequency analysis in ENERCALC 3D.

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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.enercalc.com/e3d-user-manual/interface/toc175916526/toc161393928/toc161393851.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
